R.s.v.p.

This R-rated gem is about an author who produces a novel with characters inspired by real-live Hollywood stars. When the book is turned into a film, the producers throw a party and invite all the films' real-life "characters" to celebrate its release and learn that they are featured in the film. All's well until a body turns up in the author-party host's swimming pool. However, there are plenty more bodies to be seen in this one--the kind with hearts still beating--because this comedy is loaded with nudity.
