When Massive Dynamics founder William Bell makes his debut in the season finale of Fringe, Walter Bishop won't be the only one seeing a familiar face. Fansite Fringe Television has confirmed that Bell, who'll make his first television appearance in the first season finale of the Fox show (He's already appeared in the comic book tie-in's flashback scenes), will be played by Leonard Nimoy, continuing his association with JJ Abrams, Roberto Orci and Alex Kurtzman beyond next month's Star Trek movie revival. The episode will air May 12th. [Fringe Television]
