I'm doing a very funny show in which we talk about issues. I speak at Aids charities and things. It's great to do something fun with our days and yet we're told we're doing something important.

I love playing anyone that does stuff that I don't do. The fun of playing an assassin is that I've never killed anybody. The fun of playing a brilliant musician is that I don't actually play any instruments.

I think we all realize that anyone can - and has - gotten AIDS. So there's obviously still a lot to be done.

I had run into Kari Lizer at an airport, I think, and she said, "Would you come on the show [ The New Adventures Of Old Christine]?" And I said, "God. Absolutely."

Every actor has periods of their life that are a little less busy than others, and that was just a time when I needed that. And to be back on a sitcom stage, with Julia [ Louis-Dreyfus], was really, really fun.

My wife is a real camper; it's a nice way to bond.

It was a film [The Lost World], and it's a sequel at the same time. The first shot on the first day was from the sequel to the movie they hadn't made yet. But yeah, it was a pretty amazing experience running around the jungle for that.
