Rosalina voice actress Brie Larson is apparently pretty good at keeping secrets. The Marvel Cinematic Universe star filmed a video in May at the grand opening of Super Nintendo World in Orlando about getting to play the cosmic princess in The Super Mario Galaxy Movie.
On Instagram, Larson shared the video–along with a few pictures–showing her excitement about becoming Rosalina. “I’m hiding inside a warp pipe right now. I’m going to be in the next Super Mario movie,” the actress said with a smile. “It’s called Super Mario Galaxy, and I play Rosalina. It is an absolute dream come true.”
Nintendo and Universal announced Larson’s casting during a Nintendo Direct earlier this week. The presentation featured the first trailer for The Super Mario Galaxy Movie, which also sees the introduction of Uncut Gems co-director Benny Safdie as the voice of Bowser Jr. The trailer offers a ton of Easter eggs for Mario fans.

It’s exciting to see Brie Larson taking on the role of Rosalina in the Super Mario Galaxy movie! Her enthusiasm for the character really shines through, and it’s always great to see talented actors stepping into beloved roles. Looking forward to seeing how she brings Rosalina to life!
performance will definitely bring a unique touch to the character. It’s interesting how Rosalina’s backstory adds depth to the film, which might resonate with fans who appreciate more than just the gameplay. I’m looking forward to seeing how they portray her in the movie!
