Attack of the Giant Leeches (1959), starring Ken Clark, Yvette Vickers, Bruno VeSota, Michael Emmet

Synopsis of Attack of the Giant Leeches

In Attack of the Giant Leeches, radiation has caused ordinary leeches to mutate into giant monsters. They threaten the folks in a small bayou town. Can our local protagonists stop them?


  • Ken Clark (12 to the Moon) … Steve Benton. Local game warden, investigating the spate of disappearances in the swamp. Shockingly, authorities don’t believe that giant leeches are the cause.
  • Yvette Vickers (Attack of the 50 Foot Woman) … Liz Walker. Local … let’s say, woman of easy virtue. She makes a habit of cheating on her overweight, slobbish, husband, Dave. Which is a fatal mistake, when he forces her (and her final boyfriend) into the swamp. Where the giant leeches snack on them.
  • Jan ShepardNan Greyson. Steve’s girlfriend, and Doc’s daughter.
  • Michael Emmet (Night of the Blood Beast) … Cal Moulton. Liz’s latest, and final, “boyfriend”.
  • Tyler McVey (Lt. Robin Crusoe, U.S.N.) … Doc Greyson. Steve’s friend and mentor, who helps him blow up the leeches in their underground cavern.
  • Bruno VeSota (The Undead) … Dave Walker. Overweight, unattractive, but in love with his unfaithful wife Liz. Almost feel sorry for Dave.
  • Gene Roth (The Spider, Dunked in the Deep) … Sheriff Kovis
  • Dan White (Jesse James Meets Frankenstein’s Daughter) … Porky Reed
  • George Cisar (Billy the Kid Versus Dracula) … Lem Sawyer

Editorial review of Attack of the Giant Leeches courtesy of Amazon.com

It”s hard to say whether this is a low-rent Southern Gothic melodrama or a monster movie; it seems that director Bernard Kowalski couldn’t make up his mind which genre to pursue. A local poacher turns up in the swamp half-dead with sucker marks all over his body. Soon after, a fat slob bartender (Corman regular Bruno VeSota) finds his hottie of a wife making out with her boyfriend and forces them into the swamp at gunpoint. From there, the two become a leech snack.

When more people disappear in the bayou, the local game warden and resident scientist (isn’t there always one, regardless of how remote the place is?) take it seriously and discover the monstrous bloodsuckers. Despite the grade-Z trappings of this movie, threadbare plot, and ludicrous monsters, there are still some chilling and effective moments, such as the scene where doomed victims of the leeches are left to watch in horror as their attackers approach in their lair. The mutated leeches are a result of radiation (but of course). At a scant 62-minute running time, this is some prime drive-in trash, and it”s over with before you even have a chance to get sick of it. –Jerry Renshaw
