The Opposite of Sex is a 1998 film written and directed by Don Roos. It stars Christina Ricci, Martin Donovan and Lisa Kudrow. The film marked departures for both Ricci and Kudrow, cast against type for the roles they were known for at the time (Ricci for adolescents in The Addams Family and Casper, Kudrow for being the resident airhead on Friends). Ricci went on to star in such films as Sleepy Hollow, Monster, Black Snake Moan, and Speed Racer.
