When you're managing an emergency department, you're trying to keep everybody calm, so when an emergency comes in the door, everyone can do their best work.

There are very few horror shows, where you have a long running arc. Most horror shows play as a sort of an anthology. Buffy - a terrific show - had the-demon-of-the-week. Twilight Zone - X Files - these things had an anthology approach. Our show is a long running drama with the same creatures every week.

My time as showrunner on The Walking Dead has been an amazing experience, but after I finish season three, it’s time to move on. I have told the stories I wanted to tell and connected with our fans on a level that I never imagined. It doesn’t get much better than that. Thank you to everyone who has been a part of this journey.

One of the things I've learned by working on the 'Walking Dead' and other TV shows is to be more tolerant of other people's process.

I went to NYU undergraduate, then for a Master's in English, and got a summer job at St. Vincent's. I was a ward clerk handling everything in an intensive care unit.

I created a show called 'Crash' for Starz, which was their first original drama, and that was not a good experience. I had a great time working with the cast and crew, but it was a young network and an intrusive studio, and to be honest I didn't really enjoy the movie 'Crash.
