Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen (Super Mario Bros.: The Great Mission to Rescue Princess Peach) is a 1986 ultra rare anime film that was only released in Japan. It was produced by Nippon Television and Grouper Productions in order to promote the Famicom Disk System version of Super Mario Bros. 2.
It has gotten a reputation due to its strange plot and for being the first film based on Nintendo's Super Mario Bros. license, predating 1993's live-action Super Mario Bros. starring the late Bob Hoskins.
Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen was released in theaters on July 20, 1986 in Japan. It was later released on VHS and became one of the rarest VHS tapes of Japan. It was never released in stores, as it was only a rental tape.
The plot of the film is about Mario and Luigi getting sucked into their Famicom game (the Japanese equivalent to the NES) and find out that Princess Peach has been kidnapped by King Koopa. She must be saved by the two plumbers. In order to rescue her, the two must find the three powerups as follow: The Super Mushroom, The Fire Flower, and The Invincibility Star. Along the way, the brothers run into several enemies such as Goombas, Bloopers, Pirahna Plants, Lakitu, and many more. The duo arrives just in time to save Peach from a forced marriage to King Koopa, and defeat him by twirling King Koopa by the tail and throwing him. (This idea would be later recycled into Super Mario 64's Bowser battles) Peach thanks Mario for saving her (As well as for saving a prince, who, it turns out, had been put under a spell by King Koopa to be transformed into a blue dog) and the two return home, promising to visit again soon.
