I remember I had scenes with Melinda McGraw in "Ides Of March" that I didn't have in "Video Vigilante," but I can't quite picture that other character. But it was Vancouver, and that year was crazy

Seinfeld [show] had been so huge for me. It was one of those things where I discovered Seinfeld really early and was making sure everyone I knew was watching it. I would tape it on VHS and show it to people that hadn't seen the show yet.

I think there's a certain objectivity that comes from being Canadian. You're partly British and partly American; you have a good bird's-eye view of both countries. So much of the comedy that comes out of Canada is impersonation - it's less 'look at me' than it is 'look at me playing other people.

[The Lost world] was a learning experience. I remember we were shooting a scene in which I dive out of a boat into a river to save the kid that's in the movie. And there's no mention of a stuntman, and I was like, "No, I'll go in." Nobody questioned. I never asked if maybe there was malaria in the water. And I was wearing these tall boots.

So this ["Grant MacLaren"] was a chance to sort of go back and do a more leading man. But instead of just solving crimes like a CSI show, this leading man is, like the other travelers, not who he appears.

I have accomplished a lot, but it didn't happen overnight for me. I was 35 when I got the show, and had been working professionally for 15 years. It would be a lot weirder if I were in my early 20s and stumbled into it.

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.
