Curse of the Faceless Man is a 1958 horror film directed by Edward Cahn and starring Richard Anderson (Forbidden Planet). Jerome Bixby (who wrote several Star Trek: TOS episodes) did the screenplay, and Gerald Fried (who wrote music for Star Trek: TOS, including the fight music for Amok Time) did the music. I enjoyed this one. It's available on DVD.

DVD Talk calls it "an eerie and atmospheric tale that's more enjoyable than it has any right to be" and closes by saying, "Technically it is a solid film with good composition and careful lighting and that goes a long way towards making it a fun movie." AMCtv has an overview and other information, as does TCM.
