The Giant Claw (1957) The producers of this schlocky curio from the height of the '50s sci-fi boom got one thing right: They picked the single scary element of their film for the title. That claw is pretty scary. Unfortunately, it's attached to one of the dopiest-looking bird puppets this side of Sid and Marty Krofft. The plot, about a giant bird from an antimatter galaxy, which starts off by attacking airplanes and finishes off with a double assault on the Empire State Building and the United Nations, is strictly Grade-Z. At least it didn't poo on screen. That would have been frightening.
