Here's a cool clip from the movie Bronson. I love how you can feel all the anger & emotion that Bronson is holding in after he hears his girlfriend is marrying someone else. The little mouth movement he makes and eye darts all help sell this. The multiple little blinks he has when he says "congratulations" help convey all he's trying to hold back, really cool stuff. This is a really great independent movie that came out in 2008 which features an amazing performance by Tom Hardy who plays the main character I definitely recommend checking it out.
