Devil's Partner (1961)

An old man sells his soul to the devil, and turns into a young man, then uses witchcraft and black magic to win a woman from his rival.

The Alligator People (1959)

A woman in a hypnotic state recounts to two doctors the details of a horrific experience from her past life that began with the mysterious and sudden disappearance of her husband.

Despite having a silly story this is an imaginative, above-average B-movie with some memorable moments.

Halliwell (no star): "Moderately inventive 'B' chiller."

Maltin**1/2: "Strictly routine."
