Robot Monster

Robot Monster - full movie - arguably the *worst* movie ever made! So bad, it's enjoyable - see for yourself!

"Speaking of cheesy monster movies — here’s Robot Monster. Ro-Man, an alien that looks like a gorilla in a diving helmet, has destroyed all but six people on the planet Earth. He spends the film trying to finish them off. Until he falls for the young woman in the group. Love that bubble machine!"
