[[caption-width-right:350:Because of how obscure this movie is, this video cover is a definite {{Spoiler}}.]]

Before ''Series/TheSuperMarioBrosSuperShow'', but after his run on ''The SaturdaySupercade'', {{Mario}} starred in this obscure Japanese film, titled ''Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen!'' (translated: ''The Great Mission to Save Princess Peach!''), a loose AnimatedAdaptation of ''VideoGame/SuperMarioBros.''

One night, while playing his [[NintendoEntertainmentSystem Famicom]], Mario gets an unexpected visit from the lovely Princess Peach, who is on the run from evil tyrant Bowser Koopa. Bowser then shows up and kidnaps her, leaving behind the pendant that she always wears. The next day, a little dog called Kibidango shows up at the grocery store owned by Mario and his brother Luigi (yes, they're grocers in this movie) and takes the jewel. The Mario Bros. give chase after him and wind up in the Mushroom Kingdom, where they meet the wise old Mushroom Hermit. The Hermit tells them that they've been brought to the Mushroom Kingdom to rescue Princess Peach, whom Bowser intends to marry on Friday the 13th, and save the people whom Bowser has turned into useless objects. The Mario Bros. embark on this journey, along the way gathering the [[RuleOfThree three powerful items]] of the Super Mushroom, the Fire Flower, and the Starman, which help them in their quest. They make it to Bowser's castle just in time to [[WeddingSmashers crash Bowser's wedding to Peach]], Mario defeats Bowser, and [[spoiler:it turns out that Kibidango is actually Prince Hal, Peach's previously unmentioned fiancÚ, much to the disappointment of Mario, who had fallen in love with the Princess himself]].
!!!Tropes used in the movie:
* AdaptationDyeJob: Very small change, but still noticeable. Unlike the rest of the games, Mario and Luigi have black hair instead of brown.
** Most notably, Luigi's outfit is blue over yellow instead of blue over green. He also wears a blue hat instead of green.
* AffablyEvil: Bowser seemed a pretty nice guy, [[CrazyJealousGuy albeit a bit too jealous when it came to Peach]]. [[spoiler:Heck, at the end, he is seen working with Mario [[GoKartingWithBowser and liking it.]]]]
* AllLoveIsUnrequited: Bowser is a {{Yandere}} and Mario is a DoggedNiceGuy... [[spoiler:but neither of them end up with Peach. Instead, she ends up with Haru, who was really the dog traveling with Mario and Luigi.]]
* AndNowYouMustMarryMe: The entire plot revolves around this.
* AnimatedAdaptation: Notable for being the first animated adaptation based in a Nintendo game, until the animated adaptations of ''FireEmblem'' and ''{{Anime/Pokemon}}'' came out in the 90s.
** Oddly enough, the movie credited ShigeruMiyamoto as the creator of SuperMarioBros Until the 90s, Miyamoto's identity was a very well kept secret for Nintendo, who wasn't unusual for many Japanese VG companies in the 80s and 90s, mostly for preventing industrial espionage and also for keeping their privacy.[[note]]At least for Western players. In Japan, Miyamoto's identity was already public much earlier, but only until ''SuperMarioWorld'' he was credited under his real name and not under pseudonym.[[/note]]
* ArtEvolution: Luigi is designed with the taller and slimmer look he sported in the games since the U.S. version of ''VideoGame/SuperMarioBros2'', but his color scheme is a bit different from his later look (In the film, he wears a yellow shirt with a blue hat and overalls).
* AwardBaitSong: The ending theme, "Adieu, My Love", which also plays during a dream sequence where Mario dances with Peach. It's sung by then-popular J-Pop singer Mami Yamase, who also voiced Peach.
* BittersweetEnding: The fact that [[spoiler:Kibidango/Prince Hal is actually Peach's fiancÚ [[DidNotGetTheGirl upsets not only Mario]], but [[ShipSinking also the Mario/Peach fans]].]] Needless to say, the fact that [[spoiler:Prince Hal]] was never incorporated into the games should speak volumes about how many fans were upset by that revelation even back then, it could also explain why the movie has become so obscure, that it never had an overseas release.
* CanonDiscontinuity: What gave it away? A money-hungry Luigi in yellow? Buzzy Beetles being defeated by fire? The Mario Bros. being grocers rather than plumbers? Or perhaps [[spoiler:the mere ''existence'' of Prince Hal]].
* DefeatMeansFriendship: [[spoiler:Bowser at the end]]
* DidNotGetTheGirl
* {{Foreshadowing}}: A blink-and-you'll miss it in the beginning where Luigi states the gem Peach dropped [[spoiler: has a twin.]]
* GuessWhoImMarrying See Bittersweet Ending above.
* {{Greed}}: Luigi, in contrast with his portrayal almost anywhere else. This is justified, though, as his personality wasn't established when this movie came out.
* InterspeciesRomance: Completely one-sided Bowser and Peach.
* MurderTheHypotenuse: Bowser tries to kill Mario towards the end, despite Peach's pleas for him to spare him.
* ProductPlacement: Besides Mario playing with his Famicom, we see the brothers smash some blocks later in the movie, and obtaining some [[MerchandiseDriven Mario ramen cups]] out of them.
* StalkerWithACrush: Bowser claims that he loves Peach more than anyone else and spends the entire movie planning their wedding. This does make one wonder if this is the premise for the other games as well.
* TheStinger: [[spoiler:One of Mario and Luigi's regular customers walks up to the counter and is shocked to find Bowser working there.]]
* TermsOfEndangerment: Bowser refers to Peach as "Peachy-chan" (Peach Sweetie in Japanese), much to her disgust.
* ThoseTwoBadGuys: A pair of Goombas who continually try to impede on Mario and Luigi's progress.
* WhyDoYouKeepChangingJobs: Despite being dressed like plumbers, Mario and Luigi run a grocery store.
* YouDontLookLikeYou: [[spoiler:Prince Hal in the actual film doesn't look anything like he does on the poster.]]
