Accidentally Correct Writing: The "Johnny Long-Torso" invention exchange just before Monster a-Go Go, which featured an action figure that was sold in pieces to create more revenue. The episode was released in 1993, but anyone familiar with the modern-day video game industry (or the "Build a Figure" accessories meant to ensure that fans will buy every figure in the current assortment) will find the episode chillingly prophetic.
None of the actors in the 2017 revival were told who Kinga's mother was.
In an interview with Matt McGuinness (the writer/producer who also plays the guy in the purple jumpsuit that randomly appears in Carnival Magic), he sounded just as confused about what will happen with the man in the purple jumpsuit as everyone else.
And because Peter Graves showed up in so many MST'ed movies another gag was referencing his role in the last film they saw him in.
The writers were quite proud of themselves for limiting themselves to only two The Brady Bunch refs in one film co-starring Robert Reed.
They also did this for actors who weren't famous, for example the "Coffee? I like coffee" guy from Coleman Francis films (Eric Tomlin), or Depressing Dad (Malcolm Atterbury) who showed up in several unrelated episodes, and yet somehow always played a really depressing dad.
Possibly reached its zenith when they noticed an actor named Merritt Stone had showed up in several of the films they'd done, but no one was sure who he actually was. So the big running gag of The Rebel Set is Mike and Crow giving the name to the train conductor (actually played by Gene Roth, who was another recurring actor), to which Tom keeps shouting "HE'S NOT MERRITT STONE!"
Averted completely when no one at all noticed that Space Mutiny's spaceship was the Battlestar Galactica flying backwards.
Adored by the Network: Though it would wind up getting Screwed by the Network later, the old Comedy Channel considered Mystery Science Theater 3000 its flagship show - when they merged with Ha! to become Comedy Central, they threatened to cancel the merger if Ha! insisted on getting rid of MST3K in spite of the Comedy Channel's anonymity and Ha!'s comparative success. MST3K also scored an unprecedented three-year contract, which was a big factor in producing the stellar seasons 3, 4 and 5.
The only reason the tenth season happened was because the departing director of programming at Sci-Fi was a huge fan and signed off on it as his final act of business on the network.
Very much the case with Netflix, which even went to the trouble of making several short videos with Crow and Tom for its Youtube channel, including one where they pitch show ideas to the company's real life CCO!
Canon Discontinuity: The show's crew insist on referring to the first Comedy Channel season as Season One, and the first season of the Netflix revival as Season 11. The KTMA season is referred to as "Season 0" or "Season K" (for "KTMA") by fans, or "a 22-episode-long pilot" according to Trace Beaulieu. This is even lampshaded at the end of the end of the Time Travelers episode.
Kinga: Well, Max… that was the 200th episode of Mystery Science Theater 3000! What an achievement!
Max:If you count the old series which we had nothing to do with! Technically, this was our third episode…
Kinga: Ok, come on! Disney celebrates fake anniversaries all the time! “Donald Duck turns 90,” “Mickey and Minnie’s 25th Anniversary,” ”The 40th Anniversary of Pulling Song of the South Off the Shelves,” I DON’T KNOW!
IMDb considers the KTMA episodes as Season One and the Netflix series gets an entirely separate page.
From one KTMA season to two on the Comedy Channel. The latter channel merged with Ha! to become Comedy Central, and MST3K made the transition—staying for Seasons 3-7. Afterwards, Sci-Fi picked the series up for three more seasons.
Also with their DVD releases. At first, they were handled by Rhino, then they switched to Shout! Factory, who eventually bought the show.
They've channel hopped again, with the season 11 revival airing as a Netflix Original. This is even worked into the plot of the show as Kinga has to be constantly reminded that unlike previous seasons of Mystery Science Theater 3000, they're airing on Netflix which doesn't use traditional ratings, and thus her plan to make the show a ratings giant and sell to Disney cannot work as conceived.
Joel Hodgson famously left due to disagreements with Jim Mallon involving the direction the show should take in the future.
Josh Weinstein also left due to creative differences, specifically over whether riffs should be ad-libbed or scripted.
Creator Couple: Mike Nelson is married to Bridget Jones (no, not thatone) who was also a writer on the show and occasional actress, most famously playing Flavia during the Ancient Rome arc in season 8. Bonus points for when Mike had to, and could not, flirt with Flavia.
Rebecca Hanson who plays Gypsy and Synthia in addition to being a show writer, is married to fellow writer Tim Ryder (who plays Bone Head #1, and played Tom Servo on the Watch Out For Snakes tour in place of Barron Vaughan who was on paterninty leave).
Cross-Dressing Voices: Gypsy was voiced by several men during the show's original run. It wasn't until the 2017 relaunch that she started being voiced full-time by a woman.
The Danza: Michael J. Nelson played a character named... Michael Nelson. He's the biggest example but not the only one. Frank Conniff played TV's Frank and Joel also played a character named Joel, though he at least changed his character's last name from Hodgson to Robinson, except in the pilot and KTMA episodes, in which his character was also named Joel Hodgson.
The change in Joel's name was due both to the creative team wanting a more recognizable last name for Joel and an intentional reference to Lost in Space.
Carrying on the tradition, in Season 11 ("The Return"), Jonah Ray plays Jonah Heston.
Defictionalization: An invention exchange (By the Mads no less!) became a reality on Feb 1st 2014 when Crest announced it was going to bring out CHOCOLATE toothpaste! Hope Deep 13 gets a portion of the royalties.
Executive Meddling: Despite signing a show renewal contract saying that they would not re-air Season 1 of the series, Comedy Central did just that. They also reran the "special edition" version of episode 701 (Night of the Blood Beast) that aired as part of the 1995 "Turkey Day" marathon, prior to Season 7's official start.
When the show went on Sci-Fi, the network demanded that there be "story arcs". Kevin tried to explain that "there is no story arc in a puppet show!", but they didn't listen. The result is the stories of Bobo, Brain Guy, the camping planet, and the Rome arc. Unfortunately, since Sci-Fi haphazardly would air 3-4 episodes then rerun them (often out of order none the less), this forced them to have to include recaps at the start of each episode to fill fans in. And then, to add injury to insult, Sci-Fi ordered them to cut the number of host segments in half!
Comedy Central's shoddy treatment of the show was one of the reasons Penn Jillette quit as their spokesman.
Joel, during his 2014 AMA said that black and white movies riffed during the early years were blue tinted as Comedy Central thought that people would not see the difference between the Shadowrama and the film.
Sci-Fi Channel (during Seasons 8-9) demanded that the show could only feature sci-fi, horror, or fantasy related movies, though the staff tended to find rather loose definitions of the concept in order to create variety. It wasn't until Season 10 that they were allowed to do drama films again (Girl in Gold Boots, Final Justice)...though in this case it was because the show was essentially going to get cancelled anyway and nobody at the network cared anymore.
In a more extreme case, Mystery Science Theater 3000: The Movie. It was so botched that the cast ended up having to vent their anger in a Season 7 episode where they had Crow's idea for a film be butchered in similar fashion.
Hide Your Pregnancy: Kinga's wardrobe was supposed to be a lot more varied and extravagant, but Felicia Day's pregnancy meant she was stuck in her shapeless overcoat all season. It is possible that Season 12 might see more variance in Kinga's outfit.
Poopie II is INCREDIBLY hard to find, so much some fans don't even know there was a second tape. Half of it is available on the Volume 10 set, but the rest is unavailable. However, those who have seen it don't think it's as good as the first.
Marathon Running: On Thanksgiving Day, during the Comedy Central era; they called each one the "Turkey Day" marathon. Best Brains would produce special host segments and bumpers to tie the episodes together. One year they had Adam West hosting. The show premiered Thanksgiving 1988.
They were less than thrilled when it came around on them, and previously planned episode air dates were abruptly preempted by marathons of other Comedy Central shows. So much so that they cut a promo for their next episode where they talked openly about the possibility of being preempted yet again. (As an additional Take That!, the promo featured an appearance by CC's then-opaque and very intrusive network bug.)
McLeaned: Doctor Forrester was killed offscreen by his own mother in between Seasons 7 and 8, due to Trace Beaulieu leaving the show.
Milestone Celebration: The Turkey Day marathons held for much of the Comedy Central years were, in essence, this, since the show premiered on Thanksgiving. Shout! Factory, the show's home-video distributor, revived the tradition with the help of Reddit, YouTube, and Joel Hodgson himself to promote the 25th anniversary DVD set. Season 11 episode 3, "The Time Travellers", was the 200th episode.
The first is the kind where they can't clear the film rights for home video release, and are therefore legally missing. At any given time about half the series falls under that header, but YouTube and file-sharing make it a non-issue.
The second is the kind that are really, legitimately missing, as in nobody has access to them even through more underhanded means. There are only three of these; the first three KTMA (local broadcast) episodes—understandably so, as the series had yet to find a fanbase (and thus no one recorded the episodes) and aired only in one market (driving down the number of potential tape holders). Jim Mallon, the show's executive producer, recently revealed he had copies of said episodes, which he had converted to digital media and put up clips on the show's official site. However, the movie rights for those three episodes remain uncleared, and (due to the crew's low opinion of their KTMA work) are unlikely to see release any time soon, and are therefore still not accessible and therefore still missing.
As of November 2016, the first two KTMA episodes have been released, as part of a promotional package for the upcoming release of Season 11 (the first revival season).
And then there's the "lost short". There were, at one point, plans for an MST3K CD-ROM. As part of the bonuses on the disc, riffs of two shorts were filmed, Assignment: Venezuela and What's It To You, the latter being a promotional piece for Mylar. When the CD-ROM was canceled, the shorts vanished. A work print of Assignment Venezuela was found and released on DVD alongside The Killer Shrews, but What's It To You has vanished entirely; not even the script is believed to exist.
No, the Bridget Jones who wrote on the show and played Mr. B Natural and Flavia is not that one. Averted with her most recent projects since she goes by her married name Bridget Nelson now.
Network to the Rescue: When the Comedy Channel picked up MST3K, it was a little-known, low-rating cable network which was losing viewers to the more popular HA! Network. HA! offered Comedy Channel a merger to boost profits for all involved, but saw the Channel's lineup as being of little value and wanted to scrap the lot of it. Comedy Channel, however, saw MST3K as their flagship series and refused to go through with the merger if it the show wasn't kept around. HA! relented, and not only picked the show up again but signed it for three, 26-episode seasons on the initial contract, and increased its per-episode budget so it wouldn't have to rely on public-domain films. A few years later, Comedy Central, the network formed out of the merger, suddenly had no love for the show that basically put it on the map and canceled it.
This is when Sci Fi Channel stepped in—fans ran a full-page ad in Variety begging someone to pick up the show, and so they did. Unfortunately, after two years of no ratings increase, the show was put on the chopping block once again. However, Sci-Fi's departing director of programming was a huge fan of the show and signed them for a tenth and final season as one of his final acts.
Season 11 came mostly pre-funded via the Kickstarter campign. With the renewal of the ‘’The Return’’ Netflix has stepped in to pay for season 12 (and presumably any other future seasons).
The Comedy Channel/Central episodes generally featured 5-6 actors (The Mads, Joel/Mike, Tom, Crow, and sometimes Gypsy), three sets (The Mads' lab, the Satellite of Love, and the theater) and a 20+ year old bomb of a movie that they got the license for cheap, assuming it wasn't public domain and acquired for free.
The KTMA episodes were even more apparent with this. The 5-6 actors sometimes had to work around their outside schedules, resulting in some cases of Absentee Actor (even Joel missed one episode), every one of the theatre segments were improvised, the Mads' set was blatantly the studio's editing room, and they only ever used one puppet for every character. This last one may not seem like a big deal, but it resulted in the film being visible through Servo's dome.
No Export for You: Technically this applies to the whole series (aside The Movie in some regions) due its nature, but due the Keep Circulating the Tapes mentality this isn't such big of a problem when it comes to the first 10 seasons of the show. Where it gets very unfortunate is with the season 11, since the series is only released on Netflix in English speaking regions. Due the fact that Netflix has been very aggressive against use of proxies and VPN's since 2016, this is very unfortunate, especially to those Kickstarter backers on lower donation tiers. However, Shout! Factory made sure to secure worldwide distribution rights for all season 11 episodes, so the season may still be made available to other countries.
Older than You Think: In Mike's first episode as host ("The Brain That Wouldn't Die"), the invention he presents is the Gutter-Bumber-Chute; an umbrella with gutters to keep washed off rain from getting you wet. As it turns out, Mike wasn't the first person to come up with this, as there exists a Daffy Duck comic book from 1963 showing Daffy using this very same invention!
Old Shame: They requested that Comedy Central cease airing Season 1 episodes shortly before Season 4's premiere, although they still recycled some of the better material.
To quote the MST3K Colossal Episode Guide: "Q: Why have you requested Comedy Central not air the season 1 episodes? A: Because they weren't very good."
Also the KTMA episodes. As Joel explained in the "So Happy Together" retrospective (from Shout Factory's MST3K: Gamera DVD release):
Joel Hodgson: We don't count any of the KTMA's as "real" shows. I mean, granted, if people really love Mystery Science Theater and they feel they must go back and watch them, I think it's fine just to kind of learn about like, what it was like when we were starting out. But none of us feel really great about them, because we just weren't writing them. It was just the beginning of it. But along the way, we figured it out.
The Other Darrin: Tom Servo's, Crow's, and Gypsy's voice actors were all eventually replaced.
Lampshaded when Mike turns briefly into a "werecrow" and Crow tells him, "Your voice will change about every seven years."
Beginning in the season where his voice changes, Crow's line in the opening song changes to "I'm different!" in his new voice (the only thing different about him).
Also lampshaded in the first episode of the Sci-Fi era (and presumably when the voice-change happened) where Mike actually realizes that Crow's voice has changed and keeps on calling him up on that fact.
And again in the Soultaker episode, when Joel comes back and immediately notices that Crow sounds different: "Oh, you changed your bowling pin!"
When Murphy replaced Weinstein as Servo's voice actor, it was explicitly explained as Joel tweaking Servo's voice box and personality.
Apparently an irate fan sent them a large banner that read "I HATE TOM SERVO'S NEW VOICE!", which Kevin Murphy proudly hung in the Best Brains offices. Years later, Bill Corbett received a nearly identical note, which he interpreted as good-natured hazing from the fans.
Weinstein, at Cinematic Titanic live shows, will frequently introduce himself as "the Tom Servo you don't like as much."
Weinstein voiced Crow in the very first KTMA episode, Invaders from the Deep, one of the episodes released in late 2016 as a bonus episode for Kickstarter supporters. Tom Servo doesn't appear at all, other than an off-hand reference to "Beeper".
Magic Voice has changed performers more often than any of the others; in the first four seasons she was voiced by various female performers, most often Jahn Johnson and Alexandra Carr, before being played by Mary Jo Pehl in seasons 5 through 7, and then Beth "Beez" McKeever in the Sci-Fi seasons.
All three bots get new voice actors yet again in the season 11 revival. Gypsy is handwaved as having been tweaked by Jonah, but the changes to Crow's and Servo's voices are left unexplained.
Out of Order: A common practice in the Sci-Fi era was to air a season's episodes seemingly at random, which wouldn't have made much impact in the old days — if not for the fact that they also kept demanding the show contain story arcs. The crew at Best Brains was eventually left so frustrated that they had to tag "Previously On..." bumpers on the broadcast versions just to keep things coherent.
"I was really naive and as far outside of show business as you could get. I grew up in the Midwest. The first time I ever knew of a guy making movies anywhere near me was Bill Rebane. He did ‘Giant Spider Invasion’ not too far from where I lived. I remember him being on TV in Green Bay doing P.R. They were in the process of shooting, and he was trying to recruit people to be in this movie. That was my first experience, and it made me feel glamorous that it was even happening in my state.”
The Pete Best: Josh Weinstein. Josh was only 17 years old when the Comedy Channel picked up the show. The age gap between him and the other performers, as well as his objection to the less improvisational and more scripted new nature of the show after its transfer to cable, caused friction which led to his leaving the cast just as the show was beginning to take off nationally. Weinstein described his time on the show as being barely a step above being an unpaid intern as he felt his ideas for the show's direction were not being respected and dismissed out-of-hand because of his age. Even Hodgson, when asked why Weinstein left, dryly stated "He's 18 years old.".
Popularity Redo: When the show made the jump from local low-budget KTMA to the cable station Comedy Channel, they reused some host sketches in their first season and revisited movies from the KTMA era in their third.
Post-Script Season: The show ended its seventh season by resolving its entire premise, so the eighth season (on a new network) had to begin with a Reset Button, the shifting of the setting five hundred years into the future, and the introduction of a new antagonist. It survived for three more seasons, mostly because the plot of the series was never much more than a Framing Device for the slapstick and snark.
Essentially everyone for season 11, especially Jonah Ray (as the new host) and Patton Oswalt (as TV's Son of TV's Frank).
Jonah Ray was a life long fan and has previously cosplayed Torgo, complete with pizza box. He often cites Mystery Science Theater 3000 as his inspiration for wanting to get into comedy in the first place, and has repeatedly said it's his dream job, and that they're taking the host role from his cold, dead hands.
Felicia Day got cast because she approached Joel at a convention once to get a selfie with him to make her brother (also a life long MS Tie) jealous that she met Joel and he didn't. She once said that when she was 10 watching Mystery Science Theater 3000 was the highlight of her week.
Patton Oswald had been hosting promotional spots for MST during its original run, opened for Cinematic Titanic and hosted a few reunion show panels prior to being cast in the revival.
Rebecca Hanson, who plays Gypsy and Pearl's clone Synthia, used watch mass amounts of MST3K on recorded tapes, and her comedy was influenced by the show's. She first got on Joel's radar when she approached him, Trace, and Frank at an autograph booth, and Joel told her he recognized her and the other performers with her from their Second City work.
Additionally, Mike Nelson's real-life wife, Bridget Jones (no, notthatBridget Jones) appeared several times, including as Mr. B Natural, Lisa Loeb, Nuveena, Flavia, and Slicer the Nanite. She was also one of the actresses who portrayed Magic Voice before Mary Jo Pehl took over permanently. Bridget was also one of the show's writers, including a stint as a full-time member of the writing staff from season 4 onward.
Kevin Murphy's late cocker spaniel, Humphrey, played the "wolf" Pearl attempts to use in her experiment to create a werewolf. Humphrey also appeared as the dog everyone holds in their "About the Author" pictures in the Amazing Colossal Episode Guide.
Felica Day's brother is an extra in The Return. Fittingly, she got cast in the first place because she went out of her way to get a selfie with Joel at a con to make her brother jealous.
Rebecca Hanson, the voice of Gypsy, is married to Tim Ryder, who plays one of the boneheads.
Retroactive Recognition: Michael J. Nelson really stands out now during his bit parts during the Joel years, even more so than other writers like Paul Chaplin or Bridget Jones. The same can be said about Mary Jo Pehl to a lesser extent after joining Deep 13 in Season 7.
Role Reprisal: During the revival's Kickstarter fundraising phase, Joel made it clear that, despite his wanting to recast the protagonists, any surviving members of the original series who wished to play their mads for the new season would be welcomed with open arms. Mary Jo Pehl, Kevin Murphy and Bill Corbett took up his offer, reprising Pearl Forrester, Professor Bobo and The Observer respectively in several episodes.
In the case of Sci-Fi, Mike Nelson maintains that Bonnie Hammer, after taking charge at the network, said one of her priorities was, "I'm going to kill that #$%&@*! puppet show."
With Comedy Central it was a new president (Doug Herzog) cutting the show loose as part of Younger and Hipper makeover for the network, but Herzog's tone-deaf handling of the situation made things worse.
Talking to Himself: There was always at least one actor overlapping between the mad scientists and the 'bots. It got even worse in the Sci-Fi Channel era, when both Tom and Crow's actors were also playing Pearl's assistants.
The tradition is alive and well in Season 11, though this time it's Gypsy and Synthia.
Throw It In!: The crew frequently left in the less serious bloopers — robots falling apart, the actors cracking up at each other's lines, et cetera — because they felt it added a certain something to the show.
One particular example would be a skit they did when Crow got fried by Servo's Death Ray. Crow's little fire on his head after being shot wasn't supposed to spread to his eyeballs, so his head burst into flame and he started screaming, giving a literal spin of the appropriate trope.
Crow: ... Oh, my God. Well, I'll be in my trailer.
Ever wonder why Joel always sounds kind of dazed and lethargic? It's because the first episode was filmed after Joel Hodgson had gone four days without sleeping, having been running about making sure that filming would go off without a hitch. The result was basically his spaced-out persona from his stage act turned Up to 11.
Any time a bot gets damaged - even in takes that aren't used, Trace and Kevin always remained in character. For example, when Crow and Servo are dressed as ninjas and horse playing with "Snacktion" action snacks, at the end of the skit, Crow knocks Servo's head off accidentally, to which Servo freezes and Crow sheepishly states, "Uh... I broke him."
In the first segment from "Zombie Nightmare", Servo and Crow are tackling Mike as Secret Service Agents "for his protection", constantly thinking there's a gun somewhere ready to shoot Mike. When his foot is exposed, they yell, "Foot!" and pound it back down. Servo's head inevitably pops off - to which Crow screams, "HEAD!" and both bots scream panicked, before a cut to the bumper.
In the KTMA days, Gypsy was portrayed as a Cloudcuckoolander prone to bizarre non-sequitors rather than the wise Team Mom she became soon afterward. But one aspect of this portrayal ended up sticking: Upon her being asked "What's two plus two?" she responded "Richard Basehart," which evolved into her being a huge fan of the obscure actor.
Jonah's Kaiju Rap (Every Country Has a Monster) was all one take. Jonah didn't plan on having the wood figures haphazardly fall everywhere, but when it happened Joel told the team to leave it in as it added a bit of the home made charm from the original series (seeing as how that number was the Win the Crowd moment of season 11 for many it seems to have worked). You can actually see him give a brief Oh, Crap! expression directly to the camera before deciding to just keep going. And it almost never happened. The take before this they got through the song perfectly, but on the zoom in for Movie Sign the camera became misaligned and it couldn't be fixed in post.
When Joel Hodgson was replaced by Mike Nelson as the show's main character, online communities were abound with flame wars between two halves of the fandom arguing over which of them was better. Joel confessed in an interview he once intentionally added fuel to the fire by anonymously commenting in these forums that he thought Mike was better than his own character just to see people bitch about it.
It's widely suspected that the decision to renew the show after the initial revival season was made quite a while before the official announcement during the Turkey Day marathon, given the time involved in not only writing and filming the show but the intensive process of selecting what movies to feature, and they held off on announcing it just to do it during the annual tradition.
Unintentional Period Piece: Many of the episodes' riffs and host segments deal with pop culture around the time they originally aired (Mike Nelson is Lord of the Dance, Mystos, etc.) According to Kevin Murphy in some behind-the-scenes material, they tried their best to avoid this trope. The official YouTube channel now releases official annotated episodes of the show to help explain some of the more dated pop culture references. It helps that many references were obscure even at the time the show was airing, so now the "period" riffs just fall into the same category as, say, the Electra Woman And Dyna Girl reference in the Operation Double 007 episode.
Once in a while, you can catch a glimpse of someone's mouth moving in the theater (this is most prominent with Crow) but no one says anything.note This is occasionally because the audio has been shifted in order to have better syncing; see the credits to Werewolf. It's likely that they're saying jokes that were cut, flubbed or perhaps censored. One such example can be found in their riff of Manos: The Hands of Fate:
Bride: The woman is all we want!
Crow:[Mouth moves, but nothing comes out]
A confirmed example of this can be found by watching the rough cut of It Lives by Night, where about 3/4 of the way through the movie, just before an ad break, Bill Corbett (as Crow) says "Fucking squeak." After they stop recording, it's remarked that they'll have to mute that one, but he still got a laugh out of the others.
During the 20th anniversary Comic-Con reunion panel, the cast was asked if they ever found a movie that was too bad to use for the show. They mentioned that a few movies they reviewed for use were great for their concept until certain scenes popped up - like, for instance, a rape scene - but out of all these they said that Child Bride was the worst, with Kevin Murphy calling it "Appalachian kiddie porn".
After Joel announced he was leaving, they actually auditioned outside talent to replace him, but, after he did well in a screen test, they decided that having Mike take over would make for a smoother transition.
Apparently they considered doing the legendary Plan 9 from Outer Space, but decided not to because A) Criswell's narration would interrupt the riffing, and B) making fun of it was considered too easy and cliche, even back then. It later got the live Rifftrax treatment.
Night of the Lepus was considered for a while (seeing as the jokes pretty much write themselves when giant killer bunny rabbits are involved) but its being from a major studio made the rights too troublesome to get. Though they still made a few references to it over the show's run, and it wound up on Rifftrax.
On the "Movie Sign With the Mads" Podcast, Frank Conniff revealed that, sometime between season 2 and 6, the crew had considered doing an episode on the failed ''Doctor Strange' Pilot Movie, and apparently got well into the writing process for it before they were told that they couldn't use it due to rights issues.
They tried to get the rights to A Case of Spring Fever for years before finally getting to riff it in the second-to-last episode. They even went so far as to make a host segment in Bride of the Monster directly based on it, knowing full well the audience would have no idea what they were referencing.
Other movies that they screened but never ended up using on the show, according to the ACEG: The Curse of the Doll People, Wild Guitar, Trog, The Terror of Tiny Town, Mesa of Lost Women, and From Hell it Came.
