The idea of future or past, either way, is a core part of entertainment. It's something we've always loved as humans. Its part of our psyche, I think.

It's a fascinating job, to come in and be the most interesting person in an episode. Whoever the guest star is, that's the job - to maintain the interest and the focus for that 42 minutes or whatever, and it should be a huge relief to those people that are the leads in the shows.

I think people do sci-fi a huge disservice by lumping it as some sort of bizarre subculture genre when I think everybody's lives are impacted by sci-fi at some point.

It's the imagination that is involved in sci-fi, and fantasy is what draws me to it. Stories, everything.

I've been lucky enough to work with some of the best TV directors there are, and I've learned from how they had to handle when things don't go quite according to plan.
