I have sporadic OCD cleaning moments around the house. But then I get lazy and I'm cured. It's a very inconsistent personality trait.
It is often difficult to watch yourself onscreen, especially 60-feet high. As an actor, it is an uncomfortable experience.
I actually find it harder to act in the scenes where there's not much happening, say having a milkshake in the diner. That is far harder to do than straight scenes where there's a drama going on and you have something to do.
I have seen 'Thor', yeah. It's fantastic. Being that close to something, it's often pretty hard to watch yourself, but the film in so many ways is so impressive that I was swept along with it like an audience member, and that's a pretty good sign.
