Mario Movie Sequel: Wario Spoilers Emerge!

The Super Mario Galaxy Movie, set for release on April 1, 2026, has suffered a significant spoiler ahead of its premiere. A UK cinema chain's website synopsis unexpectedly revealed Wario's inclusion in the film's plot. This leak indicates Wario will be part of an evil alliance with Bowser Jr., a character previously confirmed as an antagonist voiced by Benny Safdie.

This revelation is a setback for Nintendo and Universal, who seemingly intended to keep Wario's big-screen debut a secret. As of February 23, 2026, the plot brief containing this spoiler has not been removed, suggesting the film's distributors may be unaware of the leak. Other confirmed characters include Princess Rosalina, voiced by Brie Larson, and Yoshi, who was teased in the previous film's mid-credits scene.
