Poor Donald Pleasence! He's been in a lot of really awful films, and this is one of the worst. He was known for putting in good performances even when handed a bad script, but in this disaster, he doesn't even try. In addition to the apathy of the cast, the scriptwriter obviously didn't care too much since this film makes absolutely no sense whatsoever. There are fissures bursting open at random, men running around in Creature from the Black Lagoon costumes, a gratuitous song, a mysterious dagger, lots of tunnels, but no logic.
