Marc Blucas

Marc Blucas, who played Buffy’s boyfriend Riley on "Buffy," has been cast in Episode 5 of "Lie to Me’s" new season. Blucas will play "Jack Rader, a slick deception expert who is a smooth combination of looks, brains and charisma. Lightman was once his mentor, until some unexplained issue caused a bitter rift in their relationship. With Lightman on vacation, Rader is called in to assist on a case... he might just have an eye on [Lightman’s colleague] Foster, and he might just try to poach some of Lightman’s staff," according to a Fox rep. I’ve got a few more news tidbits about "Lie to Me’s" new season here. And James Marsters will appear on "Lie to Me" this fall as well.
