This film, directed by Brian De Palma, is terrific in every way. It combines elements of horror, comedy, and musical. It is a sort of remake of "The Phantom of the Opera" (one of my favorite films). It also has elements of "The Picture of Dorian Gray".
The film is shot wonderfully with crazy angles and insane wide lenses. The acting is very good with performances by William Finley, Jessica Harper, and Paul Williams. Paul Williams also wrote the music for the film. The music is fantastic.
Look for an opening narration by Rod Serling. He mentions Disneyland!
B+ I recommend it.
