"I regard romantic comedies as a subgenre of sci-fi, in which the world operates according to different rules than my regular human world. For me, there is no difference between Ripley from “Alien” and any Katherine Heigl character. They are equally implausible. They’re all participating in a similar level of fakey razzle-dazzle, and I enjoy every second of it."

I don't think I love them quite as much as she does, but I enjoy them sometimes and feel the same way in terms of them being sci-fi. When I was a kid, I loved reading fantasy novels. I'm not as into them anymore, but I've always had an strong fascination with world-building, which has stayed with me. I'm always intrigued by how more "reality-based" genres, such as romantic comedies, world-build in a fantasy-like way.
