Stillman was asked about the actors dancing and how he got around the actors' being insecure about it.
"Some people were really comfortable with it. I think all the women were really comfortable with it and Matt Ross, who has become a director, he really made it a great comic thing. And then, Robert Sean Leonard was just sensational. And that’s my favorite scene in the movie: Kate Beckinsale and Chloë Sevigny are dancing and having a really good time, and then the camera pushes in on them through a whole crowded dance floor. It’s a Chic song, I think “Everybody Dance.” Robert Sean Leonard arrives playing the Tom character and he and Chloë start dancing."
