Probably the biggest challenge is actors, no matter how talented the actor is they don't have the capability of being in more than one place than one particular time, which is very vexing.

I'm a very big believer that the reason you've seen this huge surge in superheroes both on television and in film is...part of it of course is zeitgeist. There's no denying that there's a huge appetite on the part of the audience in both TV and film for these kind of adventures.

When I write a film, the film gets handed off to a producer and a director and I go my merry way. With television, I am expected and contracted to stick around and actually produce what I've written.

In part, it's so difficult to come up with something original, to come up with a character nowadays. If you created a globetrotting adventurer, he'd be compared to Indiana Jones. If you created a super spy, he'd be compared to James Bond.

Time has a certain current to it, and it wants to flow in a certain direction.

The guy who sits at the keyboard and types is so much smarter than I am. I think I got into writing so that I could spend as much time with that guy as possible.
