Lost's Fallen Star Will Shine On ChuckSIsland castaway show Lost disappointed many of its die-hard fans when its super-cute rock-star character Charlie bit the dust. Actor Dominic Monaghan still doesn't know when, or if, you'll glimpse Charlie on Lost again. But he will be back playing another charismatic rock star character... on Chuck, NBC's show about a nerd with the entire CIA/NSA databases plugged into his brain. Spoilers follow. Monaghan plays Tyler Martin, a rock star whom Chuck has to help protect from some very bad guys. Monaghan describes the character as a lunatic who's not much like his Lost character, Charlie. Tyler is a superficial guy, a definitive rock star who got into music because it was the easiest way to get free flights around the world. (As opposed to Charlie, who got into music to soothe his troubled soul.) "He’s like Charlie in a hallucinogenic dream. He’s like what Charlie would be in his most brilliant moment, but Tyler is like that all the time. So I thought it might be something that would tickle people to see." (We read a ton of pages from the script to this episode a while back, and you can read a detailed summary here.) [Doc Arzt]
