The Giant Claw is my favorite science fiction movie. In my opinion, it even ranked ahead of Them, which had my heroes Matt Dillon and Davy Crockett in it.
The Giant Claw is about a giant bird from outer space which comes from the North Pole and invades the U.S. and Canada. Our fighter planes attack it, but The Giant Claw gobbles them up. Just like the current invaders from China, it terrorizes everyone in the U.S.
As you can see in this preview, the special effects are first rate.
