The latest cast member of The Super Mario Bros. Galaxy Movie has been devoted to the game for years. In the MCU, Brie Larson is best known for playing Carol Danvers/Captain Marvel. But next year, she's joining the Nintendo universe in The Super Mario Bros. Galaxy Movie. Larson is set to provide the voice of Mario's new friend, Princess Rosalina. Years ago, Larson was an avid Super Mario Galaxy player, and she had an appropriate response to ex-boyfriend when he said she was too devoted to the game. Larson shared the story in 2020 (via Nintendo Life) when she launched her YouTube channel. In her initial video, Larson noted that she became a gamer because of her love for Super Mario Bros. and The Little Mermaid on the NES. She went on to say that she threw her first boyfriend out of the house because she was trying to beat the final level of Super Mario Galaxy. "He said that I was 'taking it too seriously,' so I threw him out of my house," recalled Larson. Nintendo and Universal have released a new trailer for The Super Mario Bros. Galaxy Movie, which features a glimpse of Rosalina. In the games, Rosalina watches over the universe from the Comet Observatory and she was one of Mario's primary allies and friends. Several of the cast members from the first film are reprising their roles, including Chris Pratt as Mario, Anya Taylor-Joy as Princess Peach, Jack Black as Bowser, Charlie Day as Luigi, Keegan-Michael Key as Toad, and Kevin Michael Richardson as Kamek. Benny Safdie is also joining the cast as Bowser Jr., and he appears to be the film's main villain. The Super Mario Galaxy Movie will be released in theaters on April 3, 2026. To celebrate the film, Nintendo recently released Super Mario Galaxy and Super Mario Galaxy 2 on Switch.
