I've done other things, but it always seems like my sci-fi projects have been what people respond to the most, because those fans are extraordinary, so passionate.

You're not just writing in a vacuum, and then handing it over to someone else to shoot. You're writing, and then getting feedback from the actor and hearing their voice and how they play things.

Every day on the set, things change. You move things around. The actors are creating the roles and bringing them to life, and bringing the moments to life, as they happen. That's the best thing about television. I think it gets misunderstood, when there's one credit that says, "Written by," because that's certainly not the way it happens, in real life.
