This 1957 film is about a gigantic bird that can fly at supersonic speed, and the devastation it leaves in its path. The actual “Giant Claw” is not shown until later in the film, as scientists and military people are trying to figure out what the hell it is. So when the creature is finally shown, the effect is stunningly hilarious. Even an 8 year kid can marvel at the special effects which supposedly were done on the cheap in Mexico. The preview trailer is gutsy, in that they actually show all the big goofy effects, daring you to pay money and watch the film.
