After escaping Retik’s clutches, Cody and his colleagues devise a plan to enter the villain’s headquarters. Once there, they inject nitrous oxide into the ventilating system, knock out the bad guys, and steal the atomic ray gun. The plan works fine, but as they make their getaway with the gun, Cody and his sidekick Ted are pursued by Moon Men in a souped-up moon tank and trapped in a cave. Aiming a steady atomic ray at the cave entrance, the Moon Men melt the rock walls and cause molten lava to rush towards Cody and Ted.
Former child actor Johnny Downs earns top billing in this low-budget horror film, but the real star is the mad doctor George Zucco. The British-born character actor plays Dr. Lorenzo Cameron, a discredited — and quite mad — medico who has discovered a way to turn his helper, Pietro (Strange), into a wolf man.
The lycanthropic experiments succeed, and although Dr. Cameron spouts plans of turning his discovery into a weapon in defense of the civilized world, he instead unleashes his creation on those fellow scientists who had engineered his ouster from academia.
Before long, the good doctor is unable to control the wolf man, who threatens to kill everything in his path. Only newspaper reporter Tom Gregory (Downs) and Lenora (Nagel), Cameron's innocent daughter, may be able to stop the monster. A perennial cult favorite. 
- The Mad Monster was released on the heels of The Wolf Man (1941) but cost a fraction of Universal's elaborate lycanthropic exercise.
- Glenn Strange, who plays the unfortunate dimwit that gets turned into a werewolf, would later take up the role of Frankenstein's Monster in several of Unversal's features.
- Originally released on May 8th, 1942, The Mad Monster is tied with The Corpse Vanishes (which was released on the same day) as the oldest film used on MST3k.
Segment Two: Tom flirts with Joel's blender.
Segment Three: Joel answers the Bots' questions about the wolf man.
Segment Four: Joel switches Crow's and Servo's heads to near-disasterous consequences.
Ending Segment: The Bots say a good thing and bad thing about the movie for RAM chips.
- Host Segment Two is the source of a notorious outtake in which Tom flubs a line and then announces that he is "gonna go f*ck myself..." It is notoble since Josh Weinstein continues to operate Tom's mouth even after the take has been blown.
- Commercially released on DVD by Shout Factory in February 2009 as part of Volume XIV, a 4-disc set along with Manhunt in Space, Soultaker, and Final Justice.
- The DVD features a limited-edition poster for this episode and the original theatrical trailer for the movie.
