The Secret of The Purple Reef is a 1960 20th Century Fox CinemaScope DeLuxe Color film based on a short story by Dorothy Cottrell entitled "The Silent Reefs". It starred soon-to-be-famous actors Richard Chamberlain and Peter Falk. It is a Caribbean-based mystery involving the disappearance of a ship called the Cloud.
Although considered a "B" film, The Secret of The Purple Reef is notable in that it introduces Richard Chamberlain and Peter Falk to moviegoers as part of their early film career.
It was Richard Chamberlain's film debut, made before finding fame as Dr Kildare. In 1986 Chamberlain called it "easily the worst movie ever made, or at least the most boring".
Brothers Mark (Jeff Richards) and Dean Christopher (Richard Chamberlain) and show up in a mid-'50s four door Citroën Traction Avant in early era San Juan, Puerto Rico. They arrive to solve the mystery of the circumstances of their father's drowning death in the Caribbean. They run up against a gang of unruly pirates who seem to know more than they reveal. One of the film's highlights is several scenes of an E.G. Van de Stadt designed 35 foot sailing yacht, the Starwright. The vessel adds to the Caribbean charm and plays an integral part of moving the pirates to other parts of the island.
The story was published in 1953.
Robert L. Lippert brought Peter Falk to Hollywood to appear in Murder Inc. Lippert liked him so much he used him on this film, which was shot in Puerto Rico. Filming took place in July 1960.
Margia Dean enjoyed working with director Witney and later hired him when she produced The Long Rope (1961).
