Attack of the Giant Leeches isn't exactly the best B monster movie I've ever seen but it isn't that bad for 1959 either. My biggest problem with this movie is that the leeches make only a short appearance in the film and when they do, you can clearly tell how badly made they are. They are pretty funny looking. There are several good scenes in the movie and for most of the characters, the acting isn't bad. I was also surprised to see that Roger Corman was the executive producer. This film is only 62 minutes long and it does keep your attention throughout. Attack of the Giant Leeches is a low budget movie and although I wish they spent more time and money working on those giant leeches, I think this film is worth looking at.
