At the beginning of the episode, Joel says that the movie one week before "Wild Rebels" was "Rocket Attack USA." In reality, the shows aired three weeks apart. At the time, the writers would not have known The Comedy Channel's scheduling, but since "Ring of Terror" was produced to air in between "Rocket Attack USA" and "Wild Rebels," this is clearly a mistake or purposeful omission by the writers.
Joel: (sees title - "Lost Continent") I lost my car keys once, but this is ridiculous!
Frank: You...are all...going...to die!
Dr. Forester twists Frank's arm. Frank: (gasp) Maurice! (gasp) Rock climbing! Rock climbing. Dr. Forester: Oh, yes. Frank: Rock climbing. Dr. Forester: Rock climbing. Frank: Rock climbing, Jerry. Dr. Forrester: Rock climbing. Frank: Rock climbing, Sylvia. Dr. Forrester: In all the excitement I forgot.
This episode is on Disc One of the Mystery Science Theater 3000 XVIII DVD set. Included is an special introduction by Frank Conniff and the film's original theatrical trailer.
This episode will be referred to in Hercules Against the Moon Men due to the rock climbing segment.
During the shot where the comic relief is being pulled up the rocks by his behind, Hugh Beaumont can be seen laughing. He can't stop himself, and hides his face from the camera. (Joel and the 'Bots don't comment on it, and this is noted by Mike Nelson in the official MST3K Amazing Colossal Episode Guide.)
The Mads force Joel into the theater before he can give his Invention Exchange.
TV's Frank refers to the Gizmonic Institute/Deep 13 camerapeople as Jerry and Sylvia. These are the mole people that are seen off and on in the first two or three seasons.
