Nintendo and Illumination Studios have officially released the first trailer for the highly anticipated Super Mario Galaxy Movie, confirming major casting news and showcasing fresh scenes that expand on the beloved Mario universe.

Debuted during a recent Nintendo Direct presentation, the trailer reveals Oscar-winning actress Brie Larson as the voice of Rosalina and acclaimed filmmaker Benny Safdie as Bowser Jr., infusing new star power into this animated adaptation. The Super Mario Galaxy Movie, set for theatrical release in April 2026, builds on the successful partnership established between Nintendo and Illumination, known for their work on the blockbuster Super Mario Bros.
