When I've had hard times in my life, the one thing about being in TV is that it's positive. I withdrew to 'Cheers,' it was familiar in that it was family. It had a kind of realistic positiveness to it.

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.

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.

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.

One of the challenges with series TV is not to give everyone all the punchlines, all the gags and all the fun stuff at the top. Everyone is so anxious, for very good reasons, to hit the ground running, but I've been on the other end of that.

The great thing about Gotham is it encompasses so many different worlds.

I think when people talk about lighter drama, they tend to use that term, not derogatorily, but 'lighter' means sort of less to a degree, but if you're an actor, light drama is often mistaken for easier drama.
