Teorema

Terence Stamp stars in Pier Paolo Pasolini’s award-winning and controversial film as a strange visitor who suddenly drops into the lives of an extremely bourgeois family. He plays both God and the Devil as he proceeds to seduce each member of the house including the maid. His divine and diabolical interaction with each character causes them to re-evaluate their belief systems and just as suddenly as he appears, he’s gone. (official distributor synopsis)
