Now this one is a gorgeous beast. It could be considered a subtle parody of the genre films of its era, but in 1958 Attack of the 50-Foot Woman was just downright scary on a number of levels.
More impressive than the monster itself herself is the production budget of $88,000. Any monster movie that can accomplish its goal on such a microscopic budget deserves recognition. Either way, some would find a 50-Foot Woman to be the perfect monster, but it all depends on your perspective. If she stepped over you, your view might be better than if she stepped on you.
The best part about the film is that it focuses on a specific problem. Instead of wreaking havoc on the world, the giant woman uses her new "power" to exact revenge on her cheating husband and his mistress.
