I actually started in the opposite place. I come from a technical background - I'm a mathematician and a programmer by trade - and I was one of those people who would watch a show and say, "Oh, that could never happen."

You know, it's hard as a writer to lose characters (and actors) you like. You really don't want them to die because you're not going to get to see them anymore.

I actually started in the opposite place. I come from a technical background - I'm a mathematician and a programmer by trade - and I was one of those people who would watch a show and say, "Oh, that could never happen."

To create a situation where each new episode has to start in the exact same place as the previous one, with the actors' hair in the exact same place, seemed crazy.

What happens is that as the scripts are rewritten and re-edited in order to make the story more compelling, you sometimes end up with what you could call a time singularity - where there's no way for everything that happens to happen in real time. It's something that you need to wink at.

The idea that you could stitch together every detail episode to episode and preserve continuity for the length of a season and tell a story while using no time cuts, no flashbacks, nothing but pure real time just seemed too difficult.

The rule, I think, is: Do your homework, learn what there is to learn about the real world, and then when you get in the room, forget it all.
