: Well, I read the script, and I just thought it was such a twisted, interesting thriller/revenge movie. I’d never read anything like it before, and I loved the fact that it was written by a woman, being directed by a woman, and from a woman’s point of view. So, it was all very attractive to me, and then of course, meeting Emerald, she’s such a vivacious character. It was love at first sight.
: There were. We were actually kind of looking at women from the ’60s—a little Brigitte Bardot…You know, it happened so fast, I had some reference, and we kind of steered a little bit away from what we were thinking in the beginning. But not too far away. Like, I did include some vintage stuff in there, and then a lot of new stuff, as well.
DEADLINE: Did you get into a backstory for Cassie with Fennell? In your mind, where does she get all the costumes that she wears to seduce so-called ‘nice guys’?: In my mind, she goes thrift shopping to get these things. She just goes and finds things, and puts them together. I mean, it’s a little creative. She’s basically creating a costume every time she goes out. You know, there’s thought behind it.
DEADLINE: As you’ve mentioned, Cassie is a character that is almost always putting on a facade of one kind or another. That being said, do you think there’s ever a scene where we see the real Cassie come through?: Yeah, I like when [she and Bo Burnham’s Ryan are] in the drugstore, singing the song. She’s wearing a cardigan with a little ’60s blouse. They’re both vintage, and it just feels like there’s more texture to it.
