What has it been like working closely with Margot Robbie on the “Birds of Prey” project?
This, I can say: [Robbie] is an amazing producer. She’s so dedicated, cares so much, she is in it and works so hard — looks through every choice, reads through every draft, and has super-smart notes. I am all about finding good people you believe in as human beings as well as being good creative partners and producers, because it’s an investment — writing these movies takes it out of you. I’m also just excited that [director Cathy Yan] is a woman and she’s Asian. That’s a big deal.
Diving into comics lore, what was it about Harley Quinn that spoke to you?
I just fell in love with Harley. She makes me laugh, but she also makes me cry.... She’s got such emotional depth that is completely contrasted by this light, superficial, fun exterior. Even in the comics when she is at her best, she’s doing something bad — and when she’s at her worst she’s doing something good. And that makes her so interesting and so much more real, because that’s what people are like in real life. Very few people are just purely heroic or purely villainous, and she is this wonderful balance of everything.
How much can you share about working on “Batgirl”?
Basically nothing, other than I’m really excited — because she’s Batgirl! She’s all the things I love about Batman. I’ve always been more interested in humans than supernatural things and monsters. People are capable of profound good, but also profound evil. The things that people will do when you back them into a corner are amazing, terrifying, and wonderful at the same time, and it draws out these primal things in us — good and bad. And that, to me, is so fascinating.
