Storyline

Ramon the alligator is flushed down the toilet as a baby and grows into a gargantuan monster by eating the corpses of laboratory animals who have undergone dubious hormone experiments, thus providing all the ecological and social subtext that one could possibly wish for, even if one doesn't normally go for films about giant alligators eating people left, right, and center--which is the inevitable and tragic result of Ramon's decision that the outside world looks rather more interesting than the sewers....

Trivia

John Sayles read Frank Ray Perilli's script for the film once and then totally scrapped it. Sayles said it was set in Milwaukee and explained that the alligator grew gigantic because of beer from a beer factory going into the sewers. See more »

Goofs

When Henry Silva and the gang member head into the alley, they see the shadow of the alligator against a wall, as it backs down into another alley. A moment later, when Silva investigates, the alligator bursts forth from under a mountain of trash bags. No explanation is given for how the alligator backed down the alley and covered itself with a mountain of garbage bags. See more »

A fun, entertaining film!

When this film turned up on T.V. I was prepared for the worst. Much to my surprise this was a good thrilling monster movie with just the right amount of tongue and cheek to make the far fetched premise acceptable; ie the idea that an alligator this big could slip in and out of the sewers with out being detected. Robert Forster as the detective out to track down the killer gator gives a good performance. ,real stand out is Henry Silva as the military man sent to destroy the monster gator. He plays him like a broad stereotype of a general from some Latin American dictatorship.

FYI: If you think the idea of a 36 foot plus alligator is impossible, there is a fossil skull on display in the American Museum of Natural History in New York of an extinct crocodile. The skull is over five feet long. Image that such monsters once did roam the earth!
