The confirmed cast for this movie includes returning voice actors and new additions. Chris Pratt returns as Mario, Anya Taylor‑Joy as Princess Peach, Charlie Day as Luigi, Jack Black as Bowser, and Keegan‑Michael Key as Toad. New cast members include Brie Larson as Rosalina, Benny Safdie as Bowser Jr., Donald Glover as Yoshi, Issa Rae as Honey Queen, and Luis Guzmán as Wart.
Rosalina’s Character Across Media
Rosalina is a recurring character in Nintendo’s Super Mario franchise, first appearing in the 2007 game Super Mario Galaxy as a cosmic guardian and caretaker of the star-like Lumas. She resides on the Comet Observatory and guides Mario through missions to collect Power Stars and restore balance to the galaxy. Rosalina has since appeared in multiple Mario spin-offs, often reflecting her cosmic abilities and connection to Luma.
Rosalina’s inclusion in both Super Mario Bros. Wonder and The Super Mario Galaxy Movie places the character in major Nintendo franchise outputs in quick succession.

The Wonder announcement builds hype for not only the game but also the upcoming movie.
Are you excited to see Rosalina on the big screen and in Super Mario Bros Wonder? Let us know your thoughts in the comments below.
Adding a new character to Wonder is fine, but Brie Larson playing her is yet another reason to skip the movie.
Sad to see that Issa Reggin is in this. I hate that monster.
Can’t stand Brie Larson. Not paying for anything she is cast in.
