A young woman who has raised a giant gorilla from an infant brings him to Hollywood years later seeking her fortune in order to save her family's ranch.
Charming rip-off of King Kong clearly aimed at a younger audience (despite a lot of violent mayhem there seem to be no fatalities) with the same great special effects and a fast-paced, lively plot with a happy ending.
Halliwell*: "Rather tired comic-sentimental follow-up to King Kong, with a tedious plot and variable animation but a few endearing highlights."
Maltin***: "Updating of KING KONG theme has comparable (and Oscar-winning) stop-motion special effects by Willis O'Brien and Ray Harryhausen, but no matching storyline, and Moore is no Fay Wray. Mr. Young is good, though."
