Frankenstein Meets the Wolf Man - 1943

Frankenstein Meets the Wolf Man is a 1943 American horror film directed by Roy William Neill and starring Lon Chaney Jr. as Larry Talbot (the Wolf Man) and Bela Lugosi as Frankenstein's monster. The script, written by Curt Siodmak, follows The Ghost of Frankenstein (1942) and The Wolf Man (1941), though with a number of retcons. Most significantly, Talbot only transforms into werewolf form during a full moon (rather than every night while wolfsbane is in bloom, as in The Wolf Man), which became a standard part of werewolf lore. The film involves Larry Talbot, who is resurrected when his tomb is disturbed. His search for a way to end his seeming immortality leads to his befriending Frankenstein's monster.
