Suffers massively from an extremely long and boring set-up and not enough giant leeches! B-movie with a huge emphasis on the 'B'. Ace costume work on the actual leeches though once they finally make it on screen. 1.5/5

Giant leeches infiltrate a Florida swamp and people begin disappearing. Typical Roger Corman 50's monster movie with no real story to speak of beyond find and kill the creatures. Has the usual corny characters and the monsters were the obligatory bizarre and cheesy creatures we've all come to know and love. Add a sexy female and there you have it. You may want to watch the MST3K version instead. -- DrNostromo.com
