[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.

I was working with David Warner and John Rhys-Davies, who is from the Indiana Jones movies.He's a very strong, strong presence, and so I had to assert myself.

I was raised on 'Get Smart' and 'All in the Family' and 'M.A.S.H.,' and certainly when 'Cheers' came along, that was a big one.

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.

I think I was very lucky that I didn't get well-known until my early thirties. If it had happened when I was younger, you might have seen me falling out of nightclubs. I think I conducted myself as a much better human being because I was already married when all that came along (I got married five months after I got the role as Will).

At home in L.A., Sunday is lazy. It's the wife and me lying in bed with coffee, watching 'The Soup' or something funny on TiVo. The kid will occasionally join us. Eventually, breakfast is at a place down the street called Paty's. And we always have some kind of great dinner - my wife makes a great roast beef.

As a television actor, there's a power you're given to use your image to do something valuable. As a parent, these messages are particularly important to me.
