The things that make me angry still make me angry. George Carlin is 67, and he's still as funny as he's ever been, and he's still angry. And that makes me feel good, because I feel like if I stick around long enough, I'll still be able to work.
Harrison Ford - one of my favorite actors - has a wonderful sense of character and depth and uniqueness to him, yet he's able to just deliver the lines without putting any English on it.
