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.

I had a couple of decent laughs on Townies, but for the most part, delivering a joke that you just know is not funny is hard.

When we started the show [Lonesome Dove], Suzanne De Passe - who had done the original miniseries and still owned the property and was turning it into this series - she brought in a lot of old friends - Diahann Carroll and Billy Dee Williams and Dennis Weaver. And we had an interesting collection off the top of these old seasoned actors. Billy Dee was lovely and iconic.

There was not an episode [on Perception] that didn't deal with some form of mental illness, either my own, or I would be the first to notice if a defendant did a certain thing that perhaps he was suffering from this. And so we got to do some really outspoken stuff for what was otherwise a crime-solving show. And it was just a really good team.

I'd done a pilot [of Townies] with Caroline Rhea [Pride & Joy] that didn't go anywhere.

When I read the script for Will & Grace in 1998, I knew I was the only guy for the part.

That was my big break [Lonesome Dove]. My first real kind of adult role on something really well-written. It was a spin-off of the miniseries, and I played Col. Mosby, a very dangerous, Southern colonel in post-Civil War, wandering the West.
