Super Mario Galaxy Movie: Rosalina, Bowser Jr., and More Characters Teased for Nintendo & Illumination's Expanding Universe

Nintendo and Illumination are poised to elevate their cinematic collaboration yet again with the upcoming Super Mario Galaxy Movie, continuing the expansion of the beloved Super Mario universe on the big screen.

Following the global success of the first Super Mario Bros.

Movie, released in April 2023, fans have been eagerly anticipating which new and familiar faces will join Mario and his companions as the franchise branches out into new adventures.

This new installment in the Mario movie series takes inspiration from the popular Nintendo Switch and legacy games, promising an even broader cast of characters.

The first movie’s post-credits scene teased Yoshi’s arrival, foreshadowing further growth in the franchise’s ensemble.

Now, official trailers for the Super Mario Galaxy Movie have confirmed the cinematic debut of two fan favorites from Nintendo’s iconic catalogue: Rosalina and Bowser Jr. In a recent interview with GamesRadar+, Chris Pratt—who voices Mario in the films—shed light on the potential for additional surprises.

When asked if there were new characters he’s particularly excited to see on screen, Pratt responded, "There definitely are some amazing ones coming, but I'm not able to reveal their identities just yet.

Some have already been introduced in the trailer, like Rosalina and Bowser Jr., but there are others who haven’t been shown and will certainly excite fans." Nintendo and Illumination have officially confirmed well-known actors bringing these characters to life.

Academy Award winner Brie Larson steps into the role of Rosalina, while acclaimed actor Benny Safdie will lend his voice to Bowser Jr.

Their inclusion signals a fresh direction and a commitment to both quality and fan appeal as the studio continues to deepen the connection to Nintendo's vast character library. With each new reveal, Nintendo and Illumination demonstrate their intent to build a larger Mario cinematic universe, much like what has been seen with the Sonic the Hedgehog movie adaptations.

Although speculations about additional characters—such as the persistent rumors of Wario’s debut—have circulated among fans, only official trailer content and cast confirmations should be regarded as factual until more is unveiled. For those eager to follow every update, current cast details and all confirmed character appearances in the Super Mario Galaxy Movie are available through official Nintendo Direct announcements and coverage on the Nintendo eShop News section.

Both Nintendo and Illumination’s partnership continues to set new records in video game adaptations, building on impressive sales and viewership milestones established since the Mario franchise’s cinematic debut. As excitement mounts ahead of the film's premiere, the promise of more unannounced characters, coupled with the return of series icons and new voices, positions the Super Mario Galaxy Movie as one of the most anticipated Nintendo adaptations for both long-time fans and newcomers alike.
