Nude Celebs: Psycho Beach Unknown - Catch a wave and a psychotic seaside killer in this comedy-horror spoof on the popular beach party movies of the 1960s. Lauren Ambrose stars as Florence, a schizophrenic surfer chick, and her alter ego, Ann, a promiscuous partier with a violent streak and a mouth like a truck driver. When a rash of sun-drenched murders occurs, "both" women become prime suspects, along with a surfing guru, a B-movie actress and a Swedish exchange student. Also starring Amy Adams, Beth Broderick.
