Cinema Snob: You're out of order. They're out of order. This whole system is out of order!
Can't believe it took this long for someone to mention how the Critic's announcement to Kevin Baugh of his intentions to invade and how he should just give up is so reminiscent of Wile E. Coyote's similar announcement to Bugs Bunny.
Very likely; Doug Walker is a huge Looney Tunes fan!
In Spoony's commentary, he reveals that Doug describes the Critic as, essentially, a human version of Daffy Duck.
The Critic himself has stated this repeatedly long before that.
Likewise, Film Brain's character seems to be a reference to Chester of the Chester and Spike Looney Tunes.
The Nostalgia Critic phoning everyone to inform them that IT'S TIME seems to reference Palpatine's spiel in Revenge of the Sith. Of course, it then backfires hysterically when everyone calls him back to ask him what he meant... Or to tell him the time.
Linkara also references one of Spoony's Strike Commando reviews when he sees an explosion hit Marzgurl. Turns out she was fine, but it doesn't stop him from telling her about Disneyland and cotton candy.
Dr. Insano: Whatever happened to the purity of unarmed combat?!
Nostalgia Critic: Well this is just superconductor electromagnetism. Certainly you've heard of it. It levitates bullet trains from Tokyo to Osaka. It will levitate my rocket chair, once it finally arrives. And it also levitates... ME.
Jesus Christ rose from the dead after three days. As did Santa Christ.
The credits are based off of the Bayeux Tapestry, and one of the pictures appears to be based off a famous picture of the Gunpowder plot.
The narrator's final summation is a nonstop Ice Cream Koan of shout out after shout out, until the Critic shoots him.
The way The Cinema Snob is ambushed in the secret meeting place by the Film Brain shouting with his thick British accent is probably a reference to the movie adaptation of 1984.
And nobody has remembered the scene reminiscent of the first brawl?
Ma-Ti: "Remember your roots, Critic. Remember your roots!"
During Rob's commentary, he notes that Jew Wario deflecting the cannonball back at Baugh was their little ode to Mary Poppins.
In Part 4, when The Cinema Snob asks about who's been listening to Baugh and everyone gets all shifty-eyed, if you listen closely, Linkara is whistling a snippet of his own theme music, as he is known to do. It helps that the theme is catchy, of course.
