"Badger sighting!"
The Internet on Mark Sheppard

A London-born actor and noted Hey, It's That Guy!, Mark Sheppard is mostly known for his television work. He's usually a single-episode guest star or a recurring bit player rather than a regular castmember, but his appearances are always memorable.

Sheppard's roles tend towards the villainous, or at least the mysterious and morally ambiguous. (When asked, he'll mention with some pride that he's never played a "bad guy".) If your favorite show featured a sinister and slightly creepy-looking Englishman for a couple episodes, it was probably him.

He also does the voice-over work for BBC America's promos, so it's also possible you'd recognize him from his voice alone. Funnily enough, at one point, he was doing a voiceover (in his British accent) introducing a show he was starring (in an American accent.)

He is the son of legendary sci-fi genre actor W. Morgan Sheppard.

Not to be confused with Brigadier General Mark Jamison Sheppard, the GDI supreme commander from Command and Conquer.
