** The only reason the tenth season happened was because Rod Perth was a huge fan and signed off on it before his departure from the Sci-Fi Channel.

** This is when [[Creator/{{Syfy}} 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, Rod Perth, was a huge fan and signed for a tenth and final season [[DyingMomentOfAwesome as one of his final acts]].

* DescendedCreator: Head writer Michael J. Nelson taking over the role of host from mid-Season 5 on (though he had previously appeared in small bit parts in several episodes by that point).

* NamesTheSame:
** No, the Josh Weinstein from this show is not the former writer for ''WesternAnimation/TheSimpsons''. This is why he goes by J. Elvis Weinstein now.
** It's also not the same Kevin Murphy, who not only wrote and produced ''Series/DesperateHousewives'' but also co-created the [[Film/ReeferMadnessTheMusical musical]] [[Theatre/{{Heathers}} adaptations]] of ''Film/ReeferMadness'' and ''Film/{{Heathers}}''.
** No, the Bridget Jones who served as a series writer and played Mr. B Natural and Flavia is not [[Film/BridgetJonesDiary that one]]. Averted with her most recent projects since she goes by her married name Bridget Nelson now.

** Additionally, Nelson's real-life wife, Bridget Jones ([[NamesTheSame no, not]] ''[[NamesTheSame that]]'' Literature/BridgetJones) appeared several times, including as Film/MrBNatural, 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.

** PinocchioSyndrome

** Due to rights expiring, certain episodes are no longer legally allowed to be released, such as ''Film/TheFinalSacrifice'' and ''Film/{{Soultaker}}'', thus making those sets out of print. So this trope can be cyclical as well.

*** Creator/FeliciaDay was cast because she approached Hodgson at a convention once to get a selfie with him to make her brother (also a lifelong MSTie) jealous that she met Joel and he didn't. She once said that when she was 10, watching ''[=MST3K=]'' was the highlight of her week.

* ChannelHop:
** From one KTMA season to two on the Comedy Channel. The latter channel merged with Ha! to become CTV: The Comedy Network [[note]]No new episodes aired under this channel name because it happened between the seasons (merging in April, renamed on June 1st), season 3 started the first day the Comedy Central name was used, [[https://www.youtube.com/watch?v=I1L8LGq9kAQ&list=PL_GBFWpBThw2xvkxqJxeud_UGeHgKnKwn&index=2 but reruns can be found on Website/YouTube that aired during that time]][[/note]] but due to a naming conflict with the Canadian channel CTV, it was renamed to 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 Creator/RhinoRecords' home video division, then they switched to Rhino's SpiritualSuccessor Creator/ShoutFactory, 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 as Kinga has to be constantly reminded that unlike previous seasons, they're on Netflix, which doesn't use traditional ratings, and thus her plan to make the show a ratings giant and sell to Creator/{{Disney}} cannot work as conceived.
** From Season 13 onwards, the show has moved from Netflix and is now broadcast on its own website entitled The Gizmoplex.

** Creator/ShoutFactory has announced that 12 episodes of the classic series may never be licensed, and unless that changes, Volume [=XXXIX=] is the final release of the classic series (barring re-releases of the out-of-print Rhino [=DVDs=]). Those episodes include ''Film/RocketshipXM'', ''Film/GodzillaVsMegalon''[[note]]This episode was accidentally released on original prints of Volume X, but Toho put a very fast stop on production.

** ''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 [[{{Sequelitis}} don't think it's as good as the first]]. It was finally found unlisted on [=YouTube=] after much searching, but is now privated.

* McLeaned: Dr. Forrester was killed offscreen by his mother in between Seasons 7 and 8, due to Beaulieu leaving the show. A nod to this appears in Season 12 when Dr. Erdhardt passes by Moon 13 as he's fulfilling Frank and Dr. Forrester's final wishes to scatter their ashes to the tune of "Idiot Control Now!"

** Ever wonder why Joel always sounds kind of dazed and lethargic? It's because the first episode was filmed after Hodgson had gone four days without sleep, 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 UpToEleven.

** On the "Movie Sign With the Mads" podcast, Conniff revealed that, sometime between season 2 and 6, the crew had considered doing an episode on the failed 1978 ''ComicBook/DoctorStrange'' PilotMovie, and apparently got well into the writing process for it before they were told that they couldn't use it due to licensing rights issues.

** All three hosts share, at minimum, first names with their actors (Joel Hodgson plays Joel Robinson[[note]]Except in the pilot and KTMA episodes, in which his character was also named Joel Hodgson[[/note]], Michael J. Nelson plays Mike Nelson, and Jonah Ray plays Jonah Heston). The change in Joel's surname was due both to the creative team wanting a more recognizable last name for Joel and an intentional reference to ''Series/LostInSpace''; the same applies to Jonah's surname being changed to reference Creator/CharltonHeston.

** 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 AbsenteeActor (even Joel missed [[Recap/MysteryScienceTheater3000S03E06TimeOfTheApes 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.

** All three bots get new voice actors yet again in the revival (seasons 11–present). Gypsy is handwaved as having been tweaked by Jonah, but the changes to Crow's and Servo's voices are left unexplained.
