**1/2. The problem with this film is John Phillip Law who doesn't have any charisma. Special effects are interesting and the bad guy, played by Tom Baker, saves the movie from complete oblivion. Caroline Munro plays a very healthy sexy slave/servant with no respiratory problem. A curiosity.
Though it follows a pretty straightforward plot and saves the best creatures for the end, this boy's adventure is so fun that it's forgiven. While Rosa' score helps, the highlight moment was (and still is) the Kali sword fight which contains so much adventure and excitement due to Harryhausen's creative genius.
