I first caught most of this film on T.V. I love Matthew Broderick, so I stopped to watch it. I was totally engrossed in this story, and couldn't pry myself away. It is a complicated movie, but I think Broderick did a wonderful job acting and directing. I think the thing that most captured me is not the story, but of how Broderick portrayed, Feyneman. His expressions represent his character better than any words spoken in the film. Broderick portrayed his character extremly well. He showed a man who was complicated and had many tough decisions to make, and did it to the best of his ability. On this alone, I give Infinity a 10 out of 10.
