• If there was ever an episode where the short outshines the feature, this is it. But, that being said, this was one of those times where I was expecting to struggle through the movie but was pleasantly surprised. Instead of the dull slog I remembered from previous viewings, I found it pretty entertaining and the riffing was pretty consistently good. The host segments are more good than bad as well. This really is a fun episode all around.
• Ah, Mister B. Calling it a classic short isn’t enough. It is probably the most famous of all the shorts the show presented and maybe the most watched 20 or so minutes of the entire series. I practically have the thing memorized. (Note: I admit to stealing the phrase “shrill succubus” from the ACEG. It’s just too perfect a description.)
• Can I just mention, however, that the short is in horrible shape? Mr. B’s arrival in the kid’s home has been spliced out, for example. It was probably hilarious, and therefore somebody cut it out of the print and kept it for his or her own collection of goofy footage. A lot of classic moments in movies have been lost to anonymous “collectors” savaging the only remaining copy of a particular movie.
• That being said, thanks to RiffTrax, we now know that a pristine, un-chopped-up copy of the short exists—it’s the one they used when RiffTrax re-riffed it.
• The short was filmed at the Waukegan (Illinois) Elementary School and Miami (Ohio) Sr. High School.
• Betty Luster, who played Mr. B, had a brief TV career in the early 1950s. Her first TV job was on the CBS show “Sing It Again” (1950-51), which was a game show similar to “Name That Tune.” Her second TV gig was on the NBC show “Seven at Eleven,” which was only on the air for one month in 1951.
• For a long time I wondered what the target audience of this short was. It couldn’t be the kids. It couldn’t be the school music teacher. Recently, it hit me: It’s for the PARENTS! The music teacher probably was paid to show this during parent-teacher night.
• In the segment 1, Joel says “bogart” instead of “robot.” They just keep going.
• The military guy says the river below Boulder Dam is “a mile deep in some places.” WHAT??
• The Big Head makes another appearance in segment 2.
• The gibberish Joel shouts at the end of segment 3 comes from the chaotic labels of a product known as Dr. Bronner’s Magic Soap–still available at your local health food store. There’s an explanation of this stuff here.
• Movie comment: Why didn’t they keep Glenn sedated once they got him into the hangar? (I know, they wanted to have the exciting escape scene).
• Callback: McCloud! (Pod People)
• Of course, this movie is known for the 30 seconds of color at the end, triggered by Glenn grabbing the power lines. Did Bert I. really think this was going to help the movie somehow?
• This is one of two MSTed movies (522- TEENAGE CRIME WAVE is the other) that ends at L.A.’s Griffith Observatory.
• Cast and crew roundup: Set designer Maury Hoffman also worked on “I Was a Teenage Werewolf. Assistant director/production manager Herbert E. Mendelson also worked on “The Magic Sword.” Sound mixer Ben Winkler also worked on “The She-Creature.” The voice of monster Glenn’s was provided by the great Paul Frees. We’ll hear his voice again in “The Sword and the Dragon” and “The Deadly Mantis.” By the way, he was the director and script writer for “The Beatniks.” George Becwar also appears in “Bride of the Monster.” George Milan also appears in “Merlin’s Shop of Mystical Wonders.” Roy Gordon also appears in “The Unearthly.” Dean Duncan Parkin, who played Glen the monster, also was help behind the scenes of “The Beginning of the End”… he was a grasshopper wrangler!
• CreditsWatch: This was intern Cindy Hansen’s last episode. Trace and Frank are still “villians” and Dr. F’s name is still “Forrestor.”
• Fave riff from the short: “Mom, Dad? Tell me you heard that!” Honorable mention: “Forget music! I wanna dance!”
• Fave riff from the movie: “My nurse fell down his throat!” Also: “Hee Haw, it’s Sam Wainwright!” “Sir, you just described ME!”
