The best character actors are all wonderful role-players—it's the same down-for-the-cause approach to professionalism that exemplifies a basketball team's sixth man, or a football squad's defensive lineman who keeps the quarterback safe without ever receiving any of the QB's fame. Take one look at Stanley Tucci's filmography and it's immediately clear that he's one of Hollywood's finest walking, talking examples of such a team player.

Tucci, a 27-year acting veteran, has run the gamut from major blockbusters (Captain America: The First Avenger, The Hunger Games) to small independent drams (The Daytrippers, Margin Call) and mainstream comedies (The Devil Wears Prada, Easy A). If there's one word to describe Tucci, it's, simply, "versatile," and in 2009, his ability to completely switch gears and become absolutely terrifying in Peter Jackson's The Lovely Bones (in which he played a neighborhood child murderer) earned him that ever-elusive first Oscar nomination.
