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.

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.

[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.

[Townies] was a great springboard, obviously, because Jenna [Elfman] went from that to Dharma & Greg, and a few years later, Lauren [Graham] went to Gilmore Girls.

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 jump out of the boat [in The Lost World], and I'm trying to swim to the kid, and my boots fill with water, and I start to drown, and the director has no idea why I'm flailing around. He's, "Come on, come on!" And I managed to rescue myself. I'm wet and sitting on the banks of the river, and John walks over to me and says, "Are you all right, dear boy?" "Yeah, I'm all right."

They [the Travelers] know everything about the year that they're coming into. But you can know everything and still be tripped up by the little stuff that you didn't notice. And one character's Facebook page is made up of lies. It's an interesting comment on what's been going on the last few months. We cannot rely anymore on Facebook or Twitter or Instagram. People are making up their own truths.
