"There were obvious themes, like “Don’t judge a book by its cover.” Themes of overcoming prejudice, bias, etc. There were themes about immortality, themes about integrity. These are all things that mean something to me personally. But I also don’t like to get bogged down with questions of theme too often. I like the characters to live and breathe and tell the stories they want to tell. We can figure out the theme later. This is even truer for me now than it was then. Back then, I’d use those one-word episodic titles to help me keep focused on an episodic theme, because I was told over and over how important that was. Now, when a network executive asks me about theme, I have to be careful not to roll my eyes."
