For all three the stellar performances and the subtlety in story telling.
1. Six Degrees of Separation. Stockard Channing's character evolution vs Donald Sutherland's constant. "I am a collage of un-accounted for brushstrokes"
2. Junebug. Amy Adams Amy Adams Amy Adams.
2. Smoke. Not to be confused with Holy Smoke, also starring Harvey Keitel. This scene made me cry. If you watch the film, this scene is at the end, I challenge you not to be affected by it as well.
