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

Before ''Series/TheSuperMarioBrosSuperShow'', but after his run on ''WesternAnimation/SaturdaySupercade'', [[Franchise/SuperMarioBros Mario]] starred in this obscure 1986 Japanese film, titled ''Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen!'' (translated: ''The Great Mission to Save Princess Peach!''), a loose AnimatedAdaptation of ''Franchise/SuperMarioBros''. While this film is ''very'' obscure, it's notable for being the very first full-length film adaptation of a video game, preceding the American ''Film/SuperMarioBros'' by approximately seven years.

One night, while playing his [[UsefulNotes/NintendoEntertainmentSystem Famicom]], Mario gets an unexpected visit from the lovely Princess Peach, who is on the run from evil tyrant King Koopa. King Koopa 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 Mystic tells them that they've been brought to the Mushroom Kingdom to rescue Princess Peach, whom King Koopa intends to marry on Friday the 13th, and save the people whom King Koopa 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 Flower, and the Star, which help them in their quest. They make it to King Koopa's castle just in time to [[WeddingSmashers crash the wedding]], Mario defeats King Koopa, and it turns out that Kibidango is actually Prince Haru, Peach's previously unmentioned fiancé, much to the disappointment of Mario, who had fallen in love with the Princess himself.

Oddly enough, the movie credited Creator/ShigeruMiyamoto as the creator of ''Franchise/SuperMarioBros'' Until the '90s, Miyamoto's identity was a very well kept secret for Nintendo, which wasn't unusual for many Japanese video game 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 until ''VideoGame/SuperMarioWorld'', he was credited under a pseudonym and not under his real name.[[/note]]
!!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 (blue over red on the VHS cover) instead of blue over green. He also wears a blue hat instead of green. It's made even more confusing as the poster shows him wearing blue over red.
* AffablyEvil: King Koopa 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.]]]]
** The Goombas come across this as well, with all their laid back dialogue with the Mario brothers.
* AllLoveIsUnrequited: King Koopa 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.
* 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.
* BittersweetEnding: The fact that [[spoiler:Kibidango/Prince Haru owns the other Brooch which signifies his destiny with Peach [[DidNotGetTheGirl upsets Mario]] greatly, but he accepts it as he wants her to be happy.]]
* 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 Haru]].
* CanonImmigrant: Several ideas would make it back into the series proper, including [[VideoGame/SuperMarioBros2 Luigi being taller than Mario]], [[VideoGame/SuperMarioBros3 an airship]], [[VideoGame/SuperMarioRPG Peach's Brooch]], [[VideoGame/SuperMario64 Mario grabbing Bowser by the tail]], etc.
* CharacterizationMarchesOn: Mario is deeply adamant about [[ForGreatJustice honor]] in his quest to save Peach, in contrast to his whimsical attitude seen from ''VideoGame/SuperMario64'' onward. Luigi isn't cowardly like he is in more modern portrayals, instead being defined by his {{greed}}, a trait better associated with Wario. One characterization that ''is'' consistent with the later franchise is Bowser's AffablyEvil personality, particularly his attitudes towards Peach and his [[spoiler:[[GoKartingWithBowser happily working alongside Mario and Luigi as a grocer in the end]]]].
* CoversAlwaysLie: Luigi has a red shirt on the VHS cover, as opposed to the yellow shirt he wears in the movie. Also, [[spoiler:Prince Haru in the actual film doesn't look anything like he does on the cover.]]
* DefeatMeansFriendship: [[spoiler:King Koopa works at the grocery store at the end.]]
* DidNotGetTheGirl: [[spoiler:One of the few times where Mario does not end up with Peach.]]
* {{Foreshadowing}}: A blink-and-you'll miss example in the beginning where Luigi states the Brooch that Peach dropped [[spoiler:has a twin.]]
* GettingCrapPastTheRadar: There are a few moments you wouldn't expect to see in this.
** At least one fansub translates certain lines as swearing despite the fact that the ''Mario'' series is family friendly.
** The scene where Peach makes King Koopa transform into multiple objects. One includes him turning into a "Buchimonta" and you can clearly see up his "dress".
** The whole premise revolves around a spike-shelled turtle (practically) forcing a human to marry him. Throughout her scenes, Peach voices her contempt to the whole situation.
** The mushrooms that alter people's moods
* {{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.
* GuessWhoImMarrying: Peach [[spoiler:ends up marrying Prince Haru, her fiancé]].
* IWantMyBelovedToBeHappy: While shocked to learn that [[spoiler: Peach is already engaged to Prince Haru, Mario wishes her happiness for their future.]]
* InterspeciesRomance: Completely one-sided King Koopa and Princess Peach.
* MurderTheHypotenuse: King Koopa 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 [[TheMerch Mario ramen cups]] out of them.
* StalkerWithACrush: King Koopa claims that he loves Peach more than anyone else and spends the entire movie planning their wedding.
* TheStinger: [[spoiler:One of Mario and Luigi's regular customers walks up to the counter and is shocked to find King Koopa working there.]]
* TermsOfEndangerment: King Koopa refers to Peach as "Peachy-chan" (Peach Sweetie in Japanese), much to her disgust.
* ThoseTwoBadGuys: A pair of Goombas continually try to impede on Mario and Luigi's progress.
* TrickingTheShapeshifter: Peach attempts this by asking King Koopa to transform into things to entertain her. When he turns into a teddy bear, she grabs him and locks him in a chest. A few seconds later, he returns to his regular form and bursts out of the chest, telling her "nice try".
