Did You Know?


In an interview, writer Ron Kivett said the script was inspired by an article he read about a species of 'walking' catfish that could live in water and on land. The article theorized that the fish were possibly a mutation. Doctor Leopold refers to the same species of fish in his voice-over narrative. See more »


In one wide shot, the creature wears tennis shoes while returning to the lab. See more »


Sheriff Krantz: Well, I ain't seen that college education of yours do us much good so far.
Marine Biologist Rex: Walking fish wasn't part of the curriculum. They didn't teach us how to be kind to sheriffs, either - but I'm trying.
Sheriff Krantz: You better be, boy.

Z sub A and A sub T
25 January 2004 | by (United States) – See all my reviews

I actually really liked this film, but I am also a big fan of cheap, trashy, ugly little films from the 60s and 70s. This is one of the cheapest and ugliest, but it has a rough appeal to it nonetheless.

A nerdy, evil little scientist who looks like Elmer Fudd decides to turn himself into a giant fish monster, and succeeds...sort of. Actually, it looks like he slapped some mud on a gas mask and donned a suit made of out dirty Glad garbage bags. But if you like your monsters goofy, you'll like this one. Anyway, our bad tempered fish monster goes on a killing spree in remote Florida. When he's not killing, he's ogling a beautiful blond in a bikini and a conveniently beautiful scientist whose fatal mistake was to disrobe in front of the window and put on a pretty sun dress.

This film is absolutely ludicrous, but it's also a lot of fun. The unhappy ending was not something I saw coming, and was a shock since this film seemed to so very badly want to recapture the glory days of mad-scientist-making-monsters-in-their-basement-labs movies from the 50s. If you want to see a lot of truly stupid yokels getting killed, then this movie is for you. It's just bad enough to be entertaining.
