Did You Know?


According to the Medved brothers' book "The Golden Turkey Awards", director Phil Tucker attempted suicide after the release of this film due to the overwhelmingly negative critical reaction it received. He put a gun next to his head and pulled the trigger. He missed. See more »


As is well known, this film was shot entirely in Bronson Canyon. In at least one shot, both the top of the canyon and a house are visible. What's more, the house's resident (a woman wearing a housedress) can be seen standing in her driveway watching the film crew shooting the strange sci-fi movie below. See more »

Ultra Low Budget Nonsense!
8 September 2004 | by (Ottawa, Ontario, Canada) – See all my reviews

"Robot Monster" has got to be one of the all time turkeys. It was apparently filmed in 3-D and it appears that that was where most of the meager budget went. The "monster" of the title is is the now legendary someone in a gorilla suit wearing what appears to be a diving helmet.

The story involves the monster being sent to earth from God knows where, to eliminate the remaining humans in advance of the ultimate take over of earth by the Robot Monsters. You see, the Robot Monsters have destroyed civilization except for a family of five people (and one boy friend), who are immune to detection by the monsters due some kind of cure all anti-biotic.

The family includes the father (John Mylong), the mother (Selena Royle), a scientist daughter Alice (Claudia Barrett), her boy friend Roy (George Nader) and two younger kids, a boy Johnny (Gregory Moffat) and a girl Carla (Pamela Paulson).

We're supposed to believe that the monster and his chief "The Great One" (no not Jackie Gleason) control the entire world from an isolated cave with incredibly cheap looking "scientific" instruments. And then there's those flashbacks to dinosaurs and lizards made to look like dinosaurs. The same sequences (from stock footage no doubt) are repeated a couple of times. I guess if you saw this film in 3-D it might hold some bit of interest. But in 2-D nothing.

George Nader actually survived this turkey and went on to bigger and better things at Universal as a contract player.

Absolutely awful and well deserving of the dreaded "1".
