Phantom of the Paradise is a 1974 American rock musical comedy horror film written and directed by Brian De Palma and scored by and starring Paul Williams.

A naïve young singer-songwriter, Winslow Leach (William Finley) is tricked by legendary but unscrupulous music producer Swan (Williams) into sacrificing his life's work.
