Oscar winner Brie Larson reveals playing Princess Rosalina in The Super Mario Galaxy Movie is a deeply personal, full-circle moment. The actress, known for her portrayal of Captain Marvel and her Best ActressOscar-winning performance in Room, shared her childhood connection to the Super Mario franchise in a candid interview with Cosmopolitan UK.

Childhood dreams realized

Larson reminisced about playing Super Mario Galaxy with her younger sister, Milaine, during their childhood in Sacramento, California. “I’ve always loved video games. Some people assume they’re only for a certain type of person but I denounce that idea… It’s art, it’s for everybody,” she stated. She added that her 10-year-old self would be overwhelmed with emotion at the news of her casting.

“If I think back to [that time], I desperately wanted to be an actor, and everybody was telling me no… If I knew there was relief in the future and that I would get to live the life that I always dreamed of, I don’t think there would be any words, just tears,” Larson shared. The film marks a significant shift for the actor, who has previously worked in voice acting, but the role presented unique challenges.

A cosmic force takes shape

Larson describes Princess Rosalina as “not fully definable, because she’s everything. She’s all of the things that I think are good and true in the world.” The character is billed as “an otherworldly, strong, motherly cosmic force.” The film’s narrative, she believes, delivers a powerful message regardless of the audience’s familiarity with the Super Mario universe.

The Super Mario Galaxy Movie is now playing in cinemas across the UK and Ireland. The film’s release comes amidst ongoing discussions about the evolving landscape of animation and the enduring appeal of beloved gaming franchises.

Larson’s journey from a Sacramento childhood filled with Super Mario to voicing a central character in a major motion picture is a testament to persistence and the power of embracing unexpected paths.
