The highly anticipated first trailer for The Super Mario Galaxy Movie has finally debuted, bringing with it the exciting confirmation of voice actors for Rosalina and Bowser Jr. Throughout its history, the Super Mario gaming franchise has established itself as one of the most recognizable names in the industry, and now The Super Mario Galaxy Movie is poised to bring one of its most cherished spin-off adventures to the big screen.

Earlier this week, Nintendo surprised fans by announcing a special Direct Event, specifically noting that the presentation would not feature any game announcements and would instead focus entirely on The Super Mario Galaxy Movie. The timing aligns perfectly with renewed interest in the Super Mario Galaxy series, as both the original and sequel games have recently become available on the Switch 2. With Nintendo placing additional emphasis on the franchise to build anticipation for the upcoming cinematic release, the revelation of Rosalina and Bowser Jr.'s voice actors adds another layer of excitement for fans worldwide.

The Super Mario Galaxy Movie Welcomes Brie Larson and Benny Safdie

• The Super Mario Galaxy Movie makes its theatrical debut on April 3, 2026.
• Academy Award winner Brie Larson will provide the voice for Rosalina.
• Benny Safdie has been cast as the voice of Bowser Jr.

Brie Larson, best known for her role as Captain Marvel in the Marvel Cinematic Universe, will be transitioning from superhero adventures to the cosmic realms of Nintendo. Meanwhile, Benny Safdie will take on the role of Bowser Jr., who embarks on a mission to rescue his father. Larson has been openly enthusiastic about her appreciation for Nintendo games, making her casting as the cosmic princess particularly fitting. Film enthusiasts will recognize Benny Safdie from his multifaceted career as a director, screenwriter, and actor, with notable recent projects including The Smashing Machine, Uncut Gems, and Christopher Nolan's award-winning Oppenheimer.

The star-studded cast doesn't end with these new additions, as the original ensemble from the first film—including Chris Pratt, Anya Taylor-Joy, Jack Black, Charlie Day, and Keegan-Michael Key—are all confirmed to reprise their roles. Adapting a series as beloved as Super Mario Galaxy presents significant creative challenges, but judging from the initial trailer, Illumination Entertainment appears to be crafting a visually spectacular cinematic experience.

With the sequel scheduled for release in April, dedicated Nintendo enthusiasts have only a few months remaining before they can immerse themselves in another Super Mario cinematic adventure. The enduring legacy of Super Mario has played a fundamental role in shaping the video game industry, and witnessing these beloved characters animated on the big screen promises to evoke powerful nostalgia. Moreover, the film serves as a testament to how deeply video games have become woven into the fabric of contemporary pop culture.
