Question: I know Greg Grunberg will be leaving Alias, but do you know when he stops filming?
Answer: He already stopped. In fact, Grunberg just spent the last week filming a top-secret cameo in Mission: Impossible 3 (directed by his best bud J.J. Abrams). And as I reported in last week's AA, next month he starts shooting the NBC comedy pilot Grand Union. Someone's busy.
