Boring doesn't begin to describe this waste of time. Just talk, talk, talk about a scheme to lure tourists to a sculptor's museum. Karloff's minimal role adds nothing, not even curiosity value. Unlike "fun" bad movies (such as Horror of Party Beach, The Creeping Terror, etc.) there's no fun in this empty Cauldron at all; it's just plain bad. Pass this one by - you're not missing anything.
