How does the super mario galaxy movie expand on the first film s story?

The only verified information available concerns the 2007 video game Super Mario Galaxy, which was developed and published by Nintendo for the Wii. The game follows Mario on an interstellar mission to rescue Princess Peach and defeat Bowser, featuring gravity‑based gameplay across multiple galaxies. No source indicates that a film adaptation has been released, announced, or discussed by Nintendo or any other studio. Consequently, there is no documented storyline or plot changes that a hypothetical movie could expand upon. Without any evidence of a film, it is impossible to describe how it might build on a first film’s narrative.
