Psycho Beach Party (2000)

Spoof of 1960s Beach Party/Gidget surfing movies mixed with slasher horror films. Florence Forrest, a not-so-innocent girl in 1960s Malibu, becomes "Chicklet", the first girl surfer at Malibu Beach. Only Florence suffers from dissociative identity disorder and, occasionally, her alter ego "Ann Bowman", a sexually aggressive, foul-speaking girl, comes out, during which time several beach goers are found murdered. The suspects include Chicklet herself, surfer Kanaka, exchange student Lars, and even Chicklet's own mother.

Psycho Beach Party is a comedy movie featuring Lauren Ambrose.
