One of the tricks that you have to learn, with episodic TV, is you don't know how many years you're going to be blessed with.

he beauty of this world [of comics] is there are so many stories to tell, and there's so many wonderful characters. Wonderful characters we haven't even begun to introduce - it's a world that is infinitely expandable.

One of the things about working for an old school studio like Warner Bros. is that there is an institutional culture and institutional memory, in terms of production design, camera work, and directors who understand how to do this kind of thing.

When you get to the fourth, fifth and sixth years of a show, it's really good to have held back, so that you have somewhere to go. That also applies to levels of violence, levels of humor, levels of production value.

It gives me vertigo to watch TV dramas.

A lot of the challenge with TV, as opposed to making movies, is that you have to leave room for the characters in the story to tell themselves. Sometimes you don't know where a character is going to go and what's going to happen to them until you've seen the actor take that part and make it their own.

One of the advantages of series TV is that you can change your mind and plan things as you go.
