At the beginning of the film, Griffin O'Neal's Skip character is blamed for an prank-turned-accident which leaves a ferryman disfigured. In a bizarre case of life imitating art, O'Neal was indicted on manslaughter charges the following year for a drug-induced boating mishap that resulted in the death of Francis Ford Coppola's son Gian-Carlo Coppola.
While the crew was lighting a scene, Deborah Goodrich began reading a Cosmo questionnaire to her costars, which elicited a huge conversation that caught the attention of director Fred Walton. A few days later, Walton handed Goodrich the magazine and a new set of questions, and asked the actresses to improvise a scene which wound up in the final cut of the movie.
The cast assembled at a hotel in Vancouver just prior to filming and began hanging out to build a rapport and hone their characters to make it more believable that they were all actually friends.
Deborah Foreman came in early to audition for Muffy, but the director and producers didn't feel she was right for the part. They were close to signing several other actresses who backed out for various reasons. Foreman really wanted the part and petitioned for another audition - she blew everyone away the second time around and landed the role.
The film had an additional alternate ending scripted at one point. In that ending Muffy is left to believe she is alone on the island. Skip bursts out of a closet and 'cuts' Muffy's throat. She screams only to have the rest of the characters, thought to be gone, enter the room laughing - they pranked her back
