Lesser Boris Karloff horror picture, notable for being the first time he played an actual member of the Frankenstein family. In his earlier (better) Frankenstein movies, he played either the monster or a non-Frankenstein scientist. This movie and the later Mad Monster Party are, I believe, the only times he played an actual Frankenstein. The story has Karloff playing Baron Victor von Frankenstein, descendant of the Frankenstein that caused all that trouble way back when. The good Baron, disfigured by Nazis during WWII, is in dire financial straits and needs money to continue his own experiments. Ask what kind of experiments and I'll look at you funny. To make some money the Baron allows a horror movie to be shot at Castle Frankenstein. Soon things are getting a little crazy and members of the film crew are being killed off by the Baron for reasons that should be pretty to predict.
Karloff always stood out in his horror films but here he plays to the rafters, no doubt overcompensating for the talky and dull script. Rudolph Anders is good as his friend and Don "Red" Barry does a decent job as the Carl Denham-esque movie director. There are a couple of pretty ladies around as well. Two of the better scenes are fake-outs that turn out to be scenes for the movie-within-a-movie. Perhaps if this movie had been more like that one it would have been more fun. As it is, it's a pretty dreary affair that drags on and on. The effects are poor and the monster, when it actually does something, is laughable. Basically this movie is a slow death by words. Only recommendable to Karloff completists.
