Regarding green screen, green screen is really like doing some stage work. You have to make believe that there is a window, make believe that something is there that is really not there and convince the audience. It's part of acting.
My goal as an actor has always been to reach a level where I can find a lot of interesting work, and I think I'm at that point now. The Oscar has given me a lot of recognition.
I'm not Jack Nicholson. I'm not Brando. But I do mumble.
