Tony Shaloub
I haven't realized how much I've seen of this guy! He's been Alexander Minion in the Spy Kids movie series (my daughter Keisha dreams of being like Carmen at the end of "Spy Kids II: Island of Lost Dreams"). He's also played Jack Jeebs in both "Men In Black" and "Men In Black II". I loved that scene in the first movie when he gets his head shot off and a new one grows back!
But my current favorite role is as Adrian Monk, the brilliant but obsessive-compulsive detective, in "Monk." I just finished watching tonight's episode.
