I've been racking my brain for a while now, I'm having great difficulty trying to identify this movie. There's a specific scene in the movie which I do remember.

It's a action/drama movie which is most likely a hollywood hit, it stars Leo Dicaprio or Brad Pitt or someone of that nature. The movie is set in a cafe/diner and he is sat opposite a lady who plays a supporting role. I specifically remember the lead role (again I don't remember who this is) holding his hand out and saying something along the lines of "Look how steady my hand is" as though he is trying to explain how he has no nerves.

This is really annoying me now I need to know what movie this was in.

Anyone know?
