Roman Polanski adapts Ira Levin's 1967 novel into this 1968 film, though adapts may not be the right word. Transcribes, maybe? The original cut was a very faithful transference of the source material into the film medium, perhaps more faithful than any novel to film adaptation has ever been. Then he let someone else edit it down to a reasonable movie.

Mia Farrow is great in it, perhaps because her personal life married to Frank Sinatra was pretty close to Rosemary's story. John Cassavetes is great in it despite Polanski's best efforts to reign him in. And I know have a least favorite cinematic satan to add to the list.
