Once again, atomic bomb testing has awakened an ancient monster.That's an extremely over used plot device but considering that this came out in 1953, there's a good possibility that this was the first movie to do it.Of course Ray Harryhausen's special effects are awesome.The beast is a rather generic looking lizard but the stop motion animation is top notch.My only problem with this movie is that the entire first half is just the first guy who saw the beast trying to convince other people that it really exists.But as soon he convinces the elderly scientist, you know what that old man is going to do.You should watch this and all Ray Harryhausen movies.
