Paul Dini quotes

The more I examined my emotions, the more I was able to put that in my writing. I wanted to concentrate more on human emotions and internal feelings in the characters, inasmuch as I could in an animated cartoon show-ostensibly one for a young audience. There were times when I felt I couldn't put the depth of feeling that I wanted to in the cartoons at that time, because it's for kids and you have to keep it kind of upbeat. But I did it where I could. And I put it in my other work as well, when I was writing things like comics and screenplays. (Paul Dini)
We came up with the idea of people who are attracted to criminals, especially those who might write to a criminal in jail saying, "I understand you, I sympathize with what you're going through,” and they just sort of pin all their hopes and dreams on somebody who they think is misunderstood but who is in fact rather dangerous. The fact that Harley might have gone from this intelligent, cool therapist to this crazed clown woman was both very interesting and very tragic to us. We thought that had the makings of a great Batman villain - like Batman himself, his villains start off human but then some tragedy happens and warps them into what they are today. View quote
