A scientist sounds like a scientist because the things that come out of their mouth don't stumble, that's all. If they [said], "And the, um, a microwave, uh," you know, then you don't sound right, but if you can just get it out without stumbling then you're going to sound fine.

One day very soon, we'll be asked: what did we do. And we will say: we did everything we could... we have to... because if we don't there won't be anyone left to ask.

I never think about awards or anything like that when I do a job. I was first named a best actor when I was 12 years old and it doesn't really mean anything when you get down to it, because there is no best. I don't get all that involved. My chest puffs up as much as I can puff it up but I am not trying to be better than the person I am acting with. I am trying to be at least as good. That's how it works.
