The female lead of Audrey was cast after the director's wife ran into Carolyn Farina while shopping at the Macy's store where Farina was working at the perfume section. She had no previous acting experience.
According to Clements, Whit Stillman wanted him to play the character of a seminary-type student who discusses the Bible with the group. Stillman later axed the character and had Clements play Tom Townsend.
Linda Gillies who played Audrey's mother is in real life the mother of Isabel Gillies who played Cynthia McLean. Linda got the role as Mrs. Rouget after Whit Stillman saw her during her visit on the set with her daughter and thought she looked motherly.
