Low budget, but a good storyline with Boris Karloff lending his expertise as a Frankenstein alumni. In this one, he has a film crew come in, pay him for the privilege of filming the monster-maker in action, and he uses the money to buy a mini-reactor to power his current project. Of course, when he starts needing spare parts, that film crew comes awfully in handy.
