Back in the 60s, Hammer films almost always were only shown at the drive-in where I lived. I usually had no way to go. This film actually was shown at one of the walk-in theaters so I was overjoyed when I saw the ads in the newspaper. Yeah, it`s not a great movie and the mechanical monsters are pretty lame. Especially the diving bell monster that attacks the ship. And I always got the impression that the high priest role was written for Christopher Lee to add some star power.
