Mark Shepard: Sci Fi superstar

He is in everything. Everything. [Link]

With his recent appearance on Doctor Who, Mark Sheppard cemented his place as science fiction's greatest character actor. But we've been loving Sheppard for years...and we assembled this video of every last one of his scifi roles to prove his awesomeness.

This covers the greatest Sheppard moments, from his recent appearances on Warehouse 13and Supernatural to his early work on The X-Files and Star Trek: Voyager. It's eighteen years worth of larger-than-life performances, snarky banter, and moral ambiguity, complete with at least a half-dozen different accents, multiple threats of bodily harm, and a couple of the most ridiculous face prosthetics we've ever seen.
