Monster a Go-Go! is a 1965 American science-fiction horror film directed by Bill Rebane and Herschell Gordon Lewis (who remained uncredited in association with this film). The film is considered to be one of the worst films ever made. Plot The plot concerns an American astronaut, Frank Douglas, who mysteriously disappears from his spacecraft as it parachutes to Earth. The policemen in one scene inspect the landing site of Douglas's capsule and notice a burned patch, only to dismiss it as a prank. The vanished astronaut is apparently replaced by or turned into a large, radioactive, humanoid monster. This is revealed when it comes into the scene and kills off Dr. Logan. A team of scientists and military men also attempts to capture the monster – and at one point succeed and imprison it in the lab, only to have it escape. Neither the capture nor the escape is ever shown, and both are simply mentioned by the narrator. At the end of the film, the scientists corner the monster in a sewer under Chicago, but the monster suddenly disappears. The scientists receive a telegram stating that Douglas is in fact alive and well, having been rescued in the North Atlantic, perhaps implying the monster was an alien impersonating Douglas. The narrator provides the film's closing dialogue: Cast Henry Hite as Frank Douglas/the Monster June Travis as Ruth Phil Morton as Col. Steve Connors Peter M. Thompson as Dr. Chris Manning Herschell Gordon Lewis as Radio announcer (uncredited) Bill Rebane as Narrator Production The film had an unusual production history. Director Rebane ran out of money while making the film. Herschell Gordon Lewis, who needed a second film to show with his own feature, Moonshine Mountain, bought the film, added a few extra scenes, included some new dialogue, and then released it, creating an odd, disjointed film with little continuity. Rebane had abandoned the film in 1961; Lewis did not finish the film until 1965, so he was unable to gather all of the original cast, resulting in almost half the characters disappearing midway through the film to be replaced by other characters who fill most of the same roles. One of the actors Lewis was able to rehire had dramatically changed his look in the intervening years, necessitating his playing the brother of the original character.
