Super Mario Galaxy Movie: Peach and Rosalina as sisters

The Super Mario Galaxy Movie, released on April 22, 2026, reveals some major details about Princess Peach’s backstory. The film has received mixed reviews, but Shigeru Miyamoto, Nintendo’s creative director, confirms that the new story elements are considered canon in the Mario universe.

Discovery of Peach and Rosalina’s relationship

In the film, it is revealed that Princess Peach and Princess Rosalina are sisters. Many had speculated for years about a possible family connection, especially after the release of the first Super Mario Galaxy nearly twenty years ago. The movie’s story confirms that the two were born from stardust and separated as children, with Peach sent to the Mushroom Kingdom for her safety. There, she was raised by the Toads and later made queen.

Miyamoto stated that these revelations will now be treated as canon in future Mario games. He emphasized that he would like to integrate this aspect of the story into the game experience, as long as it does not limit creativity.

With Miyamoto’s statement that the film’s elements are now official background information for the characters, the narrative structure of the Mario franchise changes significantly. This opens up new possibilities for future stories and development directions within the series.

Critical reception of the film

Despite the revelations and Miyamoto’s promise that the film will influence canon, the Super Mario Galaxy Movie received mostly negative reviews. Critics found that the film falls short in its storytelling and character development. In several reviews, the movie was criticized for being shallow and lacking depth, making it difficult for viewers to form a strong connection with the characters.

Why the film received such a negative response remains a topic of debate. While some reviewers see the new canon information as interesting, others feel it is not enough to save the film from its shortcomings.

The impact on the future of Mario games

Miyamoto has repeatedly said in interviews that he is cautious about establishing strict character details so as not to hinder future creativity. He stresses the importance of finding a balance between gameplay and storylines in new Mario games. With the canon of the Super Mario Galaxy Movie, the franchise could move toward a new narrative level, where the relationships between characters are explored in greater depth.

These changes could potentially lead to deeper storylines and improved character development in future Mario games, something fans have been hoping for for years. The promise of richer storytelling leaves plenty of room for speculation about how these elements will be implemented in future releases in the franchise.

Conclusion

The Super Mario Galaxy Movie not only brings its own story and character changes, but also offers a new perspective on the backstories of beloved characters like Princess Peach and Princess Rosalina. While audiences judge the film’s quality, it is clear that its impact on the Mario universe could be significant, with new story possibilities for years to come. It will be interesting to see how Nintendo uses this canon to further develop its iconic characters.
