|“||"What's a giant eye going to do, pick you up and wink you to death?"||”|
At the remote Alpine village of Trollenberg, someone or something is killing off mountain climbers. The culprits turn out to be an army of one-eyed, tentacled beasts from outer space, who hide themselves in a radioactive cloud. Crawling along like snails, these horrific creatures attempt to neutralize their human foes by pumping a freezing fog at their pursuers. It matters not at all that some of the locals have been mentally enslaved by the monsters. It's up to American scientist Alan Brooks to save the day. 
- The Trollenberg Terror was adapted for the screen by Jimmy Sangster from the popular BBC TV serial by Peter Key. The Trollenberg Terror was retitled The Crawling Eye when it was released in the U.S. on a double bill with The Cosmic Terror.
- A year before he did this movie, Forrest Tucker starred in a movie called The Abominable Snowman of the Himalayas where he confronted psychic Yetis.
- The film itself was parodied in the first season of the Warner Bros. cartoon "Freakazoid!" as "The Cloud."
- As Mike Nelson, Crow, and Tom Servo settle in their new apartment on Earth at the very end of the final MST3K episode, 1013 Diabolik, The Crawling Eye comes on the television as Mike and the bots sit down to watch, bringing the show full circle. Crow comments that the movie looks familiar.
Segment One (Invention Exchange): Joel explains the show and demonstrates the Electric Bagpipes. The Mad Scientists are introduced. Dr. Forrester injects Dr. Erhardt with an antiperspirant developed from dogs. It has some unexpected side effects.
Segment Two: Joel explains to the bots why it's a big deal for a human to lose a head.
Segment Three: Gypsy uncoils herself.
Segment Four: The bots are more horrified by Forrest Tucker than the giant eye. Joel explains why giant eyes are scary.
Ending Segment: Joel makes RAM chips, and will give the bots one only if they can tell him a good thing and a bad thing about the movie. Gypsy, of course, didn't see the movie, so Joel asks her what 2+2 equals. Gypsy answers Richard Basehart, but Joel gives her a RAM chip anyway because she answered.
- Although this was the first show produced, it may have been the 2nd show to air on The Comedy Channel 
- First occurrence of the Richard Basehart running gag.
- Joel actually blows a line in the the theater: “Pick up some ice and some cubes.” However they just keep going.
- You can see the shadows of the puppeteers on the wall during the second host segment.
- Tom walks into the theater by himself in the first movie segment, just as he often did during the KTMA episodes. Joel carries him in after the first and second host segments, and Tom seems to like it.
- BBI was using a “thinner” bluescreen level than they would use later; the result is that Crow’s “net” seems to vanish, and you can see some odd gaps between Servo and the theater seats.
- Though the opening credits contain a clip of the titular monster from this movie, they use shadowrama at the bottom from the next episode.
- "Come in Joley Poley Pudding 'n' Pie": Dr. Forester's nickname for Joel this episode is a reference to The Tale of Samuel Whiskers or The Roly-Poly Pudding a children's book that was originally published in 1908.
- The songs that Joel plays on his electric bagpipe are Amazing Grace (one of the most well known English hymns written by poet John Newton, first published in 1779) and Led Zeppelin's Whole Lotta Love, released as a single in May 1969. It was the first track on their second album Led Zeppelin II, released in October '69.
- "Sail on silver bird!": Dr. Forester is quoting the Simon and Garfunkel song Bridge over Troubled Water which was the second song in their 1970 album of the same name.
- "The serum rushes through the bloodstream like a Porsche Targa 911.." The Porsche 911 was first manufactured by the Porsche motor vehicle company in 1963. Variations of the model have been made throughout the years to present.
- "Someday you'll be ready for the Nobel Prize" "Maybe for fiction" the Nobel Prize is an annual international award that gives recognition to various fields in scientific and cultural fields. It was first awarded in 1901 and named after Swedish inventor Alfred Nobel.
- "I had to clean a Flubber spill once there" Flubber is a floating rubber (hence the name "Flubber"). It's a fictional compound that was central to the plot of Disney's 1961 film The Absent-Minded Professor.
- "... And worst of all it stars Forrest Tucker": Forrest Tucker (February 22, 1919 – October 25, 1986) was a film, stage and television actor from the 1940s until his death in 1986.

- "You're Sargent O'Rourke from F-Troop" One of the many references in this episode pertaining to Tucker's role in F-Troop.

Crow says this about actress Jennifer Jayne (1931-2006) who plays the role of psychic Sarah Pilgrim in the film during a scene where she gazes at the mountain.

- "Who's the tomato?" is a slang term referring to a beautiful young woman. It was commonly used in the 1920s.
