Blood Suckers in the Swamp
27 May 2006 | by See all my reviews

In a community nearby a swamp, a local dweller sees a couple of giant monsters but nobody believes on his words. Later, the cuckold Dave Walker (Bruno Ve Sota) finds his slut wife Liz Walker (Yvette Vickers) cheating him with his friend Cal Moulton (Michael Emmett). He chases the couple through the swamp, and forces them to jump into the water. The leeches attack them, and the shocked Dave is arrested, accused of murder. Two other locals decide to look for the bodies of Liz and Cal to get the prize of US$ 50.00 per body, and also vanish in the swamp. Finally, Sheriff Steve Benton (Ken Clark) organizes a patrol to investigate the caves under the swamp, finding the lethal giant leeches.

When I saw this B-movie the main attraction of a double-feature DVD with "The Wasp Woman", I did not resist and I bought it. This trash low-budget camp movie was a typical sci-fi / horror that I enjoyed on TV along my childhood. The story is silly and there is no explanation for the giant leeches other than a possible atomic testing in times of Cold War. The acting is very reasonable, with rednecks in the swamp area. The effects are ridiculously cheap and fumy, with a plastic fantasy of monster covering a stunt. Anyway, I found it a charming and entertaining flick visibly inspired in "Creature from the Black Lagoon". My vote is six.

Title (Brazil): "O Ataque das Sanguessugas Gigantes" ("The Attack of the Giant Leeches")
