Plot
The plot is currently unknown.

Why It Was Cancelled

 * 1) The poor reception of the first movie killed any chances of a sequel being made.
 * 2) Many stars of the film called the first one "a nightmare."
 * 3) The first film failed at the box office.
 * 4) Bob Hoskins expressed no interest in returning as his role of Mario before he died in 2014.
 * 5) John Leguizamo went on to do other projects instead of coming back as Luigi.
 * 6) Hollywood Pictures, the company that produced the film went out of business in 2007.

Results

 * The film was permanently cancelled, but a fan made comic book titled Super Mario Bros. 2 was written and acts as a sequel to the movie. Despite that, Super Mario Bros. is a stand-alone film.
 * Illumination Entertainment (the studio behind the Despicable Me franchise) is making a Super Mario film that is set to be released at some point in 2022.
