How much blow can Charlie Sheen do? Enough to kill two and a half men.

Why do all these people want [comedians] to be serious? The reason they want that is these are people who aren't funny. Anybody funny can be serious, but people who have no sense of humor, they can never be funny - and frankly, they're jealous. There's very few comic actors. Think about it. There aren't that many. It's hard because you have to be able to do both.

It's rare when you're actually making a movie and it feels like you're watching a movie in the theater. You feel like a surfer in a wave, catching the wave, going for it every time, there's electricity in the room, it doesn't feel like acting, you ride the wave.

I feel lucky that I'm working at all. I don't take any job for granted. I enjoy this. It's all enjoyable for me. It's all part of it.

At a certain point, if you work really hard and you get good and people like your work, you do deserve the fame - but you shouldn't take it for granted.

You, the actor, must be aware of when you're being funny, but the character you're playing should always be oblivious to the fact.

Movie acting is harder than doing a play. You have to be entertaining but completely natural, like Jimmy Stewart and Cary Grant. They weren't doing anything. Do you have any idea how hard that is? That's how good they were. It's crazy hard to be convincing and real. It's the most subtle, hardest thing there is.
