My favorite Sam role was in The Green Mile. What a great performance. He followed that with Galaxy Quest, which is one of my favorite spoofs. Matchstick Men was an all-round excellent movie. Another great job in Confessions of a Dangerous Mind. Heist and Joshua were okay, not great, but Sam was in them so that was all that mattered. If you haven't seen Snow Angels you need to check it out. Also has Kate Beckinsale in it.
One of today's best actors, IMO.
