The Ghost of Frankenstein

No masterpiece but better than its reputation, this picks up where Son of Frankenstein left off, with Lugosi's Igor retrieving the monster (now played by Chaney, alas) from the sulphur pit. Relishable performances from Hardwicke and Atwill as scientists at cross-purposes, the former determined to endow the monster with a sane brain, the latter slyly playing along with Lugosi's mad plan to have his transplanted so that he can dominate the world in the monster's body. The pair make it great fun.
