Definitely the best gorilla-related movie on that disc that includes only this movie and Kong Island, Bride of the Gorilla is really a morality tale, which teaches us we shouldn't commit crimes or we may turn into gorillas.
Let's talk about this movie. A guy commits crimes and turns into a gorilla. I won't ruin the amazing twist ending that will tear your little world into shreds, but let's just say that when you stare into the abyss, the abyss turns you into a "gorilla" and then the "woman you love" gets "killed" "protecting" "you."
Like a lot of cheapo 1950s genre movies, you've got a LOT of scenes of people talking about the story, with very little happening until the struggle at the very end. There are a lot of retroactively hilarious things about this one though. Like the islander police chief who was formally educated, played by Lon Chaney Jr. in the most American of American accents, who goes around staring off into nowhere and just going on and on about how his "savage mind" conflicts with his rational policeman brain. Or how you can't tell where the hell the island is, since every single character sports a completely different "ethnic" accent.
Having said that, it's not a bad movie. If you, say, are standing on a subway train in oppressive heat, surrounded by dozens if not millions of sweaty people, the number increasing stop-by-stop so that you feel like you are being slowly crushed to death by sweaty rocks wearing suits and reading newspapers, and all you've got is your cellphone with this movie on it, you really have no reason not to watch it.
