It is one of the two first films based on a video game, along with , released on the same day. It is the earliest isekai anime to involve a virtual video game world.

Plot
Mario is playing a game on his Famicom late at night when he witnesses a woman on the television screen crying for help from enemies attacking her. She escapes by jumping out of the TV and introduces herself as Princess Peach. King Koopa appears and follows her out of the TV. Mario fights him, but is no match for Koopa, who successfully captures Peach and goes back into the TV. Mario discovers a small necklace that Peach left on the floor.

The next day, while he and his brother Luigi are working at their grocery store, Mario cannot stop thinking about Peach and the necklace. Luigi claims the jewel on the necklace is said to lead its owner to the Mushroom Kingdom, a supposed land of treasures. A small dog-like creature wanders into the store and snatches the necklace from Mario, prompting him and Luigi to give chase and fall down a pipe.

When they emerge, a mushroom hermit reveals that he ordered the dog, Kibidango, to bring the brothers to him. He explains that they are now in the Mushroom Kingdom, which is being ravaged by King Koopa and his army. Angry that his marriage proposal was spurned by Peach, Koopa is turning the citizens into inanimate objects, and plans to force Peach into marriage on Friday the 13th. The hermit reveals a legend that claims the Mario Bros. can defeat Koopa, and that they will need to find the three mystical Power-Ups to overcome his magic: the Mushroom, the Flower, and the Star. With the three Power-Ups hidden throughout the Mushroom Kingdom by Koopa's forces, the Mario Bros. set out to find them, guided by Kibidango.

After a long journey with many perilous obstacles, the brothers eventually acquire all three Power-Ups. That night, Mario arrives at King Koopa's castle just as the wedding is starting. With the help of the three Power-Ups, Mario successfully defeats Koopa, breaking his spell and restoring the Mushroom Kingdom to normal. When Mario returns Peach's necklace, Kibidango reverts to his true form, Prince Haru of the Flower Kingdom. Haru explains that he is Peach's fiancé, and was turned into Kibidango by Koopa to marry her in his place. Though heartbroken, Mario wishes the couple well and promises to return if they ever need help, and as they accept it, he and Luigi begin their long journey home.

In a post-credits scene, King Koopa and his minions are now working at the brothers' grocery store as punishment.

Production and release
In 1986, Mario was already popular in Japan, so Grouper Productions collaborated with Nintendo to produce an anime film. To advertise the film, they released Mario phone cards, watches, rice containers, ramen noodles, a manga, an art book, three riddle books, a picture book, and an original soundtrack released on vinyl and cassette.

On July 20, 1986, the film was released in 200 theaters across Japan. VAP Video later released the film on retail VHS and Betamax in Japan, with no releases internationally or on DVD or Blu-ray.

Legacy
The film is one of the two first based on a video game, along with Running Boy: Star Soldier's Secret, released the same day. It predates the live-action Super Mario Bros. film by seven years. It is the earliest isekai anime to involve a virtual video game world, and the earliest isekai anime to involve the protagonist being trapped in the virtual world of a video game. Because it involves Mario playing a video game that comes to life, it is an ancestor of the "trapped in a video game" subgenre of isekai anime.

In 2023, nearly 40 years after The Great Mission to Rescue Princess Peach!, an animated film entitled The Super Mario Bros. Movie was released. It contains references to the 1986 anime film. The 2023 film grossed more than $1 billion, making it the highest-grossing film based on a video game.

Fan restoration
In July 2021, Carnivol released a 16mm film scan on YouTube and announced that fan restoration group Kineko Video would restore it in 4K, which was released on April 16, 2022.
