I think because the show ["Grant MacLaren"] is essentially a hopeful show. The show says that as bleak as the future is, the one thing that mankind developed was the ability to send their consciousness back and where a lot of the institutions of modern life have fallen apart.

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

[Jack Nash from The Andromeda Strain] was not in the original film, but he was kind of a Geraldo Rivera almost kind of reporter that had a drug addiction. We start the story in rehab, and then he gets the roots of the story. I loved him.

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.

Brad Wright, who created Grant MacLaren, had me in mind. We'd actually worked together 20 years ago. He wrote an episode of The Outer Limits that I was in in '96 or '95? So we'd been aware of each other for years. I'd lived in Vancouver off and on, where he's based. And it just came to me, and I'm always looking for something different. Perception was a different show than Will & Grace.

I have a big, long episode [in Full Circle] with Calista [Flockhart], and then my character actually carries out through a lot of it because he was a cop investigating this crime. But it is almost hard to remember, even though it wasn't that long ago. We shot it so fast. We literally shot that whole episode in one day.

The thing you realize pretty quickly, though, is that being in front of an audience whose job it is to laugh is a big pressure if the writing is not hilarious.
