In what marks his first major TV gig since Lost, Dominic Monaghan has signed on to guest-star on NBC's Chuck as -- stop me if this sounds familiar -- a free-spirited British rock star targeted for death by a shadowy group of evildoers. And the similarities to his Lost alter ego Charlie don't end there. Well, actually, yes, they do. "This is a very, very different kind of character," insists executive producer Josh Schwartz of Monaghan's metalhead, who makes an in-store appearance at Buy More and ends up getting entangled in one of Chuck's spy games. "He's a lunatic in the best sense of the word. And there's no heroin [addiction]." Monaghan's participation is only half the Feb. 2 episode's sell: It also will air partly in 3-D, piggybacking on NBC's 3-D Super Bowl stunt. (The network will broadcast the big game the night before.)
