5. Richard Jenkins in Step Brothers - Jenkins offers a great bit of catharsis and entertainment through his hilarious turn that embodies every bit of exasperation possible in his observations of the titular's pair's nonsense.
Best Scene: His dream.
4. Mathieu Amalric in A Christmas Tale - Amalric gives a terrific turn in creating the complexity of his character's unique dynamics within his family that form through his own distinct way of interacting with the world.
Best Scene: The one time he loved his mother.
3. Tom Noonan in Synecdoche, New York - Noonan as per usual gives a fascinating idiosyncratic turn that both acts as a proper representation of emotion, but also the representation of the act of the observation of such emotions.
Best Scene: His own choice.
2. Jason Butler Harner in Changeling - Although he isn't given a great deal of screentime Harner leaves an undeniable impression through his both chilling and honestly heartbreaking portrayal of a stunted and bent serial killer.
Best Scene: The execution.
1. Lee Byung-hun in The Good the Bad The Weird - Good Predictions Bryan L., Calvin, and RatedRStar. Lee delivers a great villainous turn here that successfully matches and amplifies the film's heightened tone while also delivering a palatable menace, along with even some real nuance in his exploration of what really makes his villain tick.
