Sarah Jessica Parker and Robert Downey, Jr. were initially cast to star as Nina Borowski and George Hanson.
During the scene at the auditorium, Allison Janney was disguised in man as an extra to prank Nicholas Hytner. But he didn't recognize her and filmed the scene anyway. The movie was released with Janney, appearing in several shots, as a man with a beard.
A longer kiss between two men was edited out of the movie before it was released in theaters.
