Tom Wilson has appeared in many movies and TV shows, but his mug is still most recognizable as Biff (and Griff and Buford) Tannen from the Back To The Future film franchise.
After the release of the beloved BTTF trilogy Tom couldn't escape the ghost of Biff, but rather than trying to separate himself from his Biffiness Tom embraced his status and accepted that he has "become pop art."
Tom's outlook on fame is refreshing, his passion for Pop Art is infectious, and it appears he has exorcised the ghosts of the Tannen clan with brush strokes and marvelous perspective.
