Andy Griffith, best known as either kindly small-town sheriff Andy Taylor or folksy defense attorney Ben Matlock, went years without playing villainous characters after he rose to fame on television, but broke the streak in the early 1980s when he was cast as John Wallace in Murder in Coweta County; the movie was the true story of John Wallace, a wealthy but sadistic landowner who kills one of his sharecroppers for stealing his cattle (by he and his goons beating up the hapless farmer, then pistol whipping him so hard he caused his gun to discharge), and it took a hard-nosed sheriff (Johnny Cash) to bring him to justice. A year before Matlock debuted, Griffith played Judge Julius Sullivan, a callously cruel judge who sentences two teen-aged girls to prison for a minor crime. After Matlock, Griffith returned to roles against type, playing the sociopathic JackMacGruder in the made-for-TV film Gramps; MacGruder turns even more sinister in his attempts to sexually molest his grandson, Matthew, and physically makes his true character known to anyone who stands in his way. In each of his three "bad guy" roles, Griffith retained his "small-town character" traits, making each of these roles even more memorable.
Speaking of Stephen King miniseries', his own take on The Shining contains two examples of Playing Against Type; Steven Weber (famous at the time for playing goofball Brian Hackett from Wings) played the slowly losing his mind Jack Torrence, and Rebecca De Mornay (famous for being typecast as psychotically dangerous women) played the very meek and demure wife Wendy.
Ben Browder of Farscape fame played an Ax Crazy man on CSI: Miami who set a fire that he intended to put out to prove he was good enough to join the fire department after their psychological screenings declared him unfit. The fire gets out of control and people died. His declarations that he's "A hero" are particularly disturbing as he did put out the fire, but seems unaware that people frown on that whole murder thing.
The British show Upstairs, Downstairs was loaded with actors playing against type, including Angela Baddeley, Jean Marsh, Rachel Gurney, Gordon Jackson, and Meg Wynn Owen. Angela Baddeley was so aristocratic in Real Life that her name appeared in Burke's Peerage, yet she played a servant convincingly.
Marc Warren, best known for playing a Loveable RogueWith a Heart of Gold on Hustle, stars in the TV adaptation of Hogfather as nightmarish Willy Wonka-like hitman Jonathan Teatime. And he's also played Count Dracula. Shiver. What's particularly interesting about the Hogfather role was that Warren himself thought up that presentation of Teatime and was actually hired with the expectation that he would play the character as something like a psychopathic Danny Blue.
He also played a lecherous professor on Boy Meets World who harasses Topanga and tries to get Corey kicked out of college for defending her (That of course would be Corey played by Fred's real-life younger brother Ben Savage).
Speaking of the Law and Order franchise, Fred Savage isn't the only one doing that trick. If we go to SVU, Melissa Joan Hart played a teacher raped by her student and Jerry Lewis played Detective John Munch's mentally impaired uncle Andy. And in the original, Chevy Chase played an anti-Semitic Manipulative Bastard who made his son kill a Jewish woman he had a grudge against.
Don't forget Dean Cain. To see Superman playing a serial rapist...Brrrr.
Also Stephen Colbert as the killer in an episode of L&O: Criminal Intent, as well as Whoopi Goldberg as a "Ma Barker" type gangleader, and Michael York as a metrosexual Charles Manson! Even Julia Roberts got to play a killer in Law and Order once (she took the part because she was dating Benjamin Bratt at the time). The Law and Order franchise is arguably the best place for established "good guy" actors to show that they can play villains.
Try and unhear The Fonz sneering "shut up, you stupid bitch" after being revealed to have plotted his wife's assault.
Adorable child actor Elle Fanning also played the part of an abused child who turned out to be a sociopathic liar and wound up setting one of the detectives' apartments on fire so they could stay together forever. It was very creepy.
Dakota Fanning (Elle's older sister) played an abused child with an entirely different twist in CSI: she was the product of incestuous rape, and her mother/"sister" had the rest of the family killed when her father in both senses of the word turned his attention to her.
In the same vein, notoriously sweet, good-girl actress Hilary Duff (best known as Lizzie McGuire, and for being as nice IRL as she is in most of her roles) played a neglectful, hard-partying teen mother in an episode of SVU.
Let us not forget the role he was best known for before he played Stabler: Depraved Bisexual Chris Keller on Oz. Not only does he treat Murder the Hypotenuse as a commandment regarding his lover, Beecher, he broke Beecher's arms and legs because Beecher had rejected him.
Arguably, his dramatic roles are the initial Playing Against Type for him, as through his initial stages of acting, his background was actually in comedy.
Let's not forget the original Playing Against Type actor that Law and Order exhibited: The late, great Jerry Orbach. Originally a Musical Theatre star, he was then-best known for playing sleazy Amoral Attorneys (so like Billy Flynn, a role he originated); In fact, he even played a defense lawyer on L&O before they recast him. Turning him into a jaded, snarkyLawful Neutral detective was an unexpected masterstroke, and he stayed attached to the show until his untimely death.
Orbach had played a very similar character to Briscoe in the 1981 film Prince of the City. Right before L&O, he played a sinister Mob type in Crimes And Misdemeanors.
A currently active one: Anthony Anderson's Kevin Bernard. Last longest role was as Complete Monster Antwon Mitchell on The Shield.
And then, of course, there's Richard Belzer, who before becoming Detective John Munch (on Homicide) was most widely known for his stand-up comedy.
Whoopi Goldberg, mentioned above, also played against her own sassy black woman stereotype when she played the immortal free-spirited bartender Guinan on Star Trek: The Next Generation.
Speaking of TNG, you owe it to yourself to watch the episode of Extras with Patrick Stewart. He's got some wonderful ideas for a screenplay.
And Dwight Schultz as the timid engineer Barclay, a few years after playing the clinically insane "Howling Mad" Murdock on The A-Team.
Andrew Sachs, known to most as the clumsy waiter Manuel of Fawlty Towers, played as a twitchy crafty paedophile in The Bill.
Pauline Quirke, known for her comedic fat lady role in Birds of a Feather, literally turned heads in her role as a serial killer in a crime drama called The Sculptress.
Christopher McDonald who always plays smarmy, Jerkass characters showed up in Stargate Universe, in a row everyone expected to be a smarmy, Jerkass self interested Senator as quite a few politicians have been before him in the franchise. Then he turns out to be smart and noble and ends up performing a Heroic Sacrifice to save the crew.
Bob Saget, best known as playing Danny Tanner on Full House and serving as the original host of Americas Funniest Home Videos, was and still is an incredibly vulgar stand-up comedian. He once stated in an interview he took the "clean" jobs because he needed the money for his family.
He also seemed to enjoy the dissonance and shock value that comes from people who only know his "wholesome" work discovering his stand-up comedy.
Phil Silvers, famous for playing fast-talking swindlers, appears in an episode of Kolchak: The Night Stalkers as a Jewish retiree scraping by on his pension in a decaying neighborhood. He's a thousand miles away from Sergeant Bilko and also completely convincing.
Lost has Dominic Monaghan of The Lord of the Rings fame playing Mancunian failed rock-star heroin addict Charlie Pace. Though as the show progressed and he kicked the junk, he seemed to revert to a lovable (albeit taller) hobbit.
Another example from Lost is Yunjin Kim, who gained fame in Korea playing Action Girls, but her character in Lost, Sun, is pretty much The Woobie.
Prior to The Golden Girls, Betty White had played raunchy Sue Ann on The Mary Tyler Moore Show, while Rue McClanahan had played The Ditz on Maude. Thus Betty was originally considered for Blanche and Rue was considered for Rose. Neither actress wanted to play such a similar role, so they suggested the switch. As a result, younger viewers are astonished to see their prior series.
Betty White probably shocks a lot of people with her dirty mouth when she appears in skits on the The Late Late Show with Craig Ferguson.
...as her former one-time MTM "rival" Cloris Leachman did on Dancing With the Stars and the roast of Bob Saget.
White's career has cycled through types a few times. The role of Sue Ann itself was playing against the type she'd established in various programs in the 1950s and 1960s. Then, having reestablished herself as the super-nice one on Golden Girls, she's spent the 1990s and 00s playing against it: for example, in her guest appearance in Everwood, where her character was slightly racist; or on Boston Legal, where she killed a man; or on Ugly Betty, where she played herself as a manipulative gambling addict ("All that Golden Girls money went right down the nickel slots!"), or Kitty's Jerkass mother in That 70s Show.
One of the drawing points of the film Lake Placid was the chance to see Betty White play a foul-mouthed role.
Criminal Minds enjoys casting former child and teen stars as crazed killers. James Van Der Beek (as a multiple personality stricken home invasion murderer) and Frankie Muniz (as an insane comic book artist turned gang member butcher) appeared in the second and third seasons, respectively. In the fourth season, Luke Perry and Wil Wheaton appeared as unsubs. As one cast member joked:
Matthew Gray Gubler(Spencer Reid): I'm always getting held hostage by teen idols - first James Van Der Beek was a guest star and held Reid hostage, and this time it's Luke Perry. I actually saw Scott Baio out front, and I swear he looked at me.
Comedic actors are not immune, either: Jamie Kennedy played a cannibalistic serial killer in the third season episode "Lucky", and George Costanza (Jason Alexander) played a mastermind manipulator in the fourth season episode, "Masterpiece".
Alexander also played against type with a surprisingly low-key turn as an ice-cold, utterly amoral supergenius on Star Trek: Voyager.
At the height of Seinfeld, Alexander went way against type as a charming, charismatic mentalist on Remember WENN, written by his longtime friend Rupert Holmes.
The pilot episode features DJ Qualls as one half of a serial killing partnership. Qualls had, to that point, mostly been known for playing awkward comic relief characters.
Jackson Rathbone played a janitor suspected of murdering a number of young men and the janitor's female split personality who was the actual killer. He was absolutely brilliant. It almost makes you cry when you see what he was reduced to in Twilight.
Try picturing Gideon delivering that immortal line: "Hello. My name is Inigo Montoya. You killed my father. Prepare to die." This troper never even realised it was the same actor.
Except for the occasional transsexual ex-NFL player in the The World According to Garp) or excitable airplane passenger (as originally played by William Shatner) in Twilight Zone the Movie, and a comedic role in Harry and the Hendersons.
After playing a sugary-sweet, innocent maternal character in La Ninera, Florencia Pena played the greedy, dysfunctional, politically incorrect mother in Casados Con Hijos. Guillermo Francella, whose roles as fathers are always of the Greg Brady type, was cast as the drunken, idiotic and also greedy and dysfunctional father.
The same happened in the Chilean version of Casado con Hijos. Javiera Contador plays the mother, and she actually was known as The Ingenue heroine in several telenovelas...
Another Chilean case in the 80's. Deceased lead actor Tennyson Ferrada was typecast as sweet and gentle grandpa-type mentors, but then La Ãšltima Cruz (The Last Cross) came... and he played the Magnificent BastardBig Bad patriarch.
Dianne Wiest, more usually known as the sweet, motherly type (for just a few among many examples, consider: the preacher John Lithgow's wife in Footloose, the mother in The Lost Boys, and conservative senator Gene Hackman's wife in The Birdcage), instead gets to appear as the wonderfully menacing, insane, and monstrous Evil Queen in The Tenth Kingdom. As she put it herself in the behind-the-scenes featurette, "It's quite delicious really. I get to kill anybody who gets in my way, so you'd better stay away from me. Otherwise you might end up dead."
She also then appeared as the hard-bitten D.A. in charge of Sam Waterson's prosecutor's office on Law and Order.
Michael Kostroff built his career with film after film where he played a heroic crusading lawyer. Then comes The Wire where he played Maurice Levy, Baltimore's go-to attorney for drug dealers and one of the most vile and unlikable characters in a show that deals almost exclusively with Black and Grey Morality.
Michael Shanks' main role for the past decade or so has been the nerdy, courageous archeologist Daniel Jackson, in Stargate SG-1. Then you've got Burn Notice, where he's cast as Victor, a psychotic, amoral super-scary spy, who has it in for the protagonist. It's great to watch.
Before that, he played the part of a psychopathic date rapist stalker in Judicial Indiscretions, in which he is definitely not redeemed at the end, though he is (sort of) in Burn Notice.
He was also a spy in 24, and a criminal in Eureka who nearly destroyed the entire town through his arrogance. And let's not forget his role as the sociopathic Balance of Judgement and his insane avatars in Andromeda.
While still a heroic character, his role as Carter Hall/Hawkman on Smallville is nearly the complete opposite of Daniel Jackson in terms of personality.
Done to a large extent in Roots, which largely cast actors known for positive, wholesome roles as its nastier characters, including Robert Reed, Ralph Waite, Lorne Greene, Burl Ives, Sandy Duncan, and Chuck Conners. It also went the other way by casting Ed Asner, best known as the gruff, surly Lou Grant on The Mary Tyler Moore Show, as a slave ship captain who is conflicted and tortured about his trade.
Wil Wheaton did this on not one but two CBS shows in the 2007/08 season, guest starring as a selfish comic book creator (who shoulders a cosplaying Klingon out of his way) in an episode of Numb3rs and as the aforementioned baddie of the week in Criminal Minds. A few years earlier, he played a crazy homeless guy on CSI.
Not to mention a (more comedic) douchebag version of himself on The Big Bang Theory to the point where he is now Sheldon's arch nemesis.
Eric Peterson, famous for the series Street Legal, spent most of his career playing wise, smarter characters. Contrast his role as the cranky, short tempered, yelling at butterflies Oscar Leroy on Corner Gas
Similar to the Fred Savage example above, Alan Tudyk (who is probably best remembered as the adorable pilot Wash, from Firefly), played a child molester on CSI.
Contrast his role as Doc in 3:10 to Yuma with his appearance on Dollhouse. Dude's got range.
As mentioned above, Dollhouse averted this trope with Alan Tudyk. Tudyk's first appearance on Dollhouse was as a stoner architect not unlike Wash. It turned out to be Playing Against Type after all, though, because he was actually the Joker-esque psycho Alpha.
Hugh Laurie was known in England for his comedy, particularly his cheerfully stupid roles in Blackadder and Jeeves and Wooster. Then he adopted an American accent to play a cynical, near-Heroic Sociopath genius in the American drama House. Thanks to the different accents, some people still can't quite accept Bertie Wooster and House as the same actor. It was also lampshaded in some of the FOX promos for the series, when the announcer announces Hugh Laurie's name, he then says derisively "You idiot!" before announcing that he's the star lead of House.
He played a cynic in Sense and Sensibility. The character is very similar to his House character, but is actually a decent person. And he doesn't have an American accent, obviously.
Don't forget that he also played an extremely loud-mouthed and scary IAD officer in dirty cop drama Street Kings.
The Shield is famous for its resurrection of Michael Chiklis's career, let alone allowing him to pretty much escape being typecast as the "stern, but lovable father figure" after his previous long-running series The Commish. It also re-energized the career of comedic actor Anthony Anderson, whose tenure on the show as ruthless Machiavellian drug kingpin helped open up new acting opportunities for him, ultimately culminating in him landing a main character role on Law and Order.
Michael Chiklis now stars in No Ordinary Family where he plays a nice guy once again. However, instead of a tough cop he now plays an insecure part time police sketch artist and it is the wife who is the successful scientist and breadwinner.
The Commish also to a point, as before that he was best known for his portrayal of John Belushi in Wired, the ill-conceived bio of his life. In fact, many industry insiders considered his career over before it really started because of that movie.
An in-show example of this occurs in the Christmas Special of The Worst Witch where nasty, scary and mean Miss Hardbroom is cast as the kind and benevolent Fairy Godmother in the pantomime of "Cinderella".
An example could be made of William Hartnell when he took on the role of Doctor Who in 1963, after decades of playing "Hard Men" and Barking Sergeant Majors.
Jon Pertwee was mostly known for Goons-esque comedy roles before being cast as the suave Gentleman Adventurer-style Third Doctor.
Catherine Tate was well known for being a catchphrase driven comic (which is played pretty straight in her previous appearance in the Christmas special)- she surprised everyone by pulling off a serious role in the fourth series
Rik Mayall, known in the UK for his insane and violent roles in The Young Ones and Bottom, as well as The Comic Strip Presents and other similar shows, did a non-comedic and largely straight performance as a police detective in an episode of Jonathan Creek, the first acting role he took after a serious head injury. He is also the narrator of a children's show called Jellikins / Jellabies, which is a show aimed at 2-6 year olds.
A memorable episode of ER had comedian Bob Newhart in a very unfunny role as an architect who is losing his sight and contemplating suicide.
He didn't just contemplate it.
Atsuko Tanaka is mostly a seiyuu known for her deep voice, which goes along great with professional Badass ladies with no-nonsense personality (eg: Major Motoko Kusanagi). Her deep alluring voice is also sometimes used for villainess roles. But, in Juken Sentai Gekiranger, she voiced the penguin-sensei Michelle Peng, who, while a professional in her own way, is very peppy and has a very high-pitched voice, you REALLY won't recognize her right off bat.
For five years, Michael C. Hall played the timid but well-meaning and likable David Fisher on Six Feet Under. After it ended in 2005, he returned a year later as the cunning, monstrous, and sociopathic title character on Dexter.
Do you mean well-meaning and likable cunning monstrous sociopath?
Further examples include Comic actor John Lithgow best known for 3rd Rock From The Sun as the ultra Disturbing Trinity Killer in Season Four and Jimmy Smits, known for playing noble Heroes on NYPD Blue and The West Wing as the increasingly unstable Partner in crime Miguel Prado in Season Three.
The short lived 1991 series, Good and Evil, had this trope as its selling point. Created by Susan Harris, the woman behind Soap, Benson, The Golden Girls and others, it was a soap opera spoof telling the story of two sisters, one good and one evil, and their families. The sisters were played by Teri Garr, known for her ditzy girl-next door roles, and Margaret Whitten, best known for her bitchy roles. Naturally, Garr played the bad girl, and Whitten the good girl.
Sharon Small in the TV movie No Child of Mine. She is most famous for sympathetic, genuinely good-hearted characters like Barbara Havers on The Inspector Lynley Mysteries and Trudi Malloy on Mistresses, and is absolutely adorable. In No Child Of Mine, however, she plays a pathologically, violently abusive mother, and does it so convincingly that the result can be quite literally nauseating.
Before playing Supernatural's Castiel, Misha Collins mostly played creepy guys (the serial rapist/murderer in Karla) or Russians ("Vlad" in CSI) or creepy Russians (Alexis Drazen in 24). He probably only auditioned for Castiel because the part was advertised as a demon, rather than an angel.
The humorless, uptight, conservative, virginal Cas is basically the opposite of Misha himself in every way. He has confirmed that the wildly altered future version of Castiel seen in the fifth-season episode "The End" is disturbingly similar to his real-life personality, noting that he enjoyed preparing for the orgy scenes.
Bill Engvall is mostly known for comedy (he's the "Here's Your Sign" guy). He plays Det. Jimmy Dupree in Hawtho R Nepretty damn vicious, using tactics that would probably get an actual detective reprimanded at least.
See also her playing something of an Alpha Bitch of a country singer on Nashville.
In Shining Time Station, the second Mr. Conductor is played by George Carlin. Mr. Conductor is a genuinely kind, supportive, and upbeat character, very different from Carlin's famous stage personality. In this case, George wanted to play against type very much, and this show gave him the opportunity.
Rene Auberjonois got a rep for playing an effeminate wimp during his stint on Benson, but ended up played tough guy Odo on Star Trek: Deep Space Nine, even making his voice more gravelly.
And then there was his playing a child-molesting priest on Saving Grace.
TV writing: Craig Mazin is mostly known for serving as co-writer on raunchy comedies such as the Scary Movie and The Hangover sequels, but in 2019 he created and received critical acclaim for HBO's historical drama miniseries Chernobyl.
