You'll go ape over this Saturday matinee favorite from the 1960s featuring Michael Gough as British scientist Dr. Charles Decker, who discovers a serum that transforms a lab chimp into a gorilla. By hypnotizing the creature, Decker gets it to kill his enemies, and then it terrorizes London when it grows to king-size (or is that "Kong-size"?) proportions. With Margo Johns, Jess Conrad. Standard; Soundtrack: English Dolby Digital mono.
