The Super Mario Galaxy Movie (2026)

The Super Mario Galaxy Movie (2026) is the animated sequel everyone wanted after the record-breaking 2023 original — and it sends Mario, Luigi and friends rocketing far beyond the Mushroom Kingdom. Below you will find the cast, release date, a spoiler-free story summary, audience reception and clear, up-to-date information on where to watch The Super Mario Galaxy Movie online in HD and 4K.

Movie Overview

The Super Mario Galaxy Movie is an animated space adventure from Illumination and Nintendo, distributed by Universal Pictures. It is the fourth film based on the Mario franchise and the direct sequel to The Super Mario Bros. Movie. Directed by Aaron Horvath and Michael Jelenic from a screenplay by Matthew Fogel, the film takes clear inspiration from the beloved Super Mario Galaxy video games while weaving in surprises for fans of every Mario era. Brian Tyler returns to compose the score, performed by a 70-piece orchestra with re-recorded themes from the Galaxy games.

Chris Pratt returns as Mario, with Anya Taylor-Joy as Princess Peach, Charlie Day as Luigi, Jack Black as Bowser, Keegan-Michael Key as Toad and Kevin Michael Richardson as Kamek. Joining the cast are Benny Safdie as Bowser Jr. and Brie Larson as the cosmic Princess Rosalina, the adoptive mother of the Lumas.

Release Information

The Super Mario Galaxy Movie was released in theaters in the United States on April 1, 2026, in standard, RealD 3D and IMAX formats, with a Japanese release following on April 24, 2026. It was originally announced for an April 3 date before being moved earlier. The film arrived almost exactly three years after the 2023 original, which gave Illumination time to design entirely new galactic environments.

Genre

This is family-friendly animation at its broadest: an adventure-comedy built for kids and longtime gamers alike. Expect bright, fast-paced platform-inspired set pieces, slapstick humor and the kind of four-quadrant appeal that made the first film a global phenomenon. If you enjoy big-screen animated spectacle, this sits comfortably alongside the year's other crowd-pleasers.

Story Summary (Spoiler-Free)

Mario and Luigi meet and quickly befriend Yoshi as they join Princess Peach and Toad on an adventure that launches them off the planet and across the galaxy. Out among the stars they cross paths with Princess Rosalina and her Lumas — and face off against Bowser's mischievous son, Bowser Jr. The premise lets the filmmakers reimagine the Mario universe on a cosmic scale, with new worlds, new allies and a story that is bigger in scope than the original without losing its sense of fun. We have kept this summary spoiler-free so you can enjoy the surprises yourself.

Why the Movie Is Popular

Few brands carry the built-in goodwill of Mario, and the first film proved the appetite was enormous. The sequel capitalizes on that with a beloved source game (Super Mario Galaxy is regularly ranked among the greatest video games ever made), a returning all-star voice cast and a marketing blitz that included Nintendo Direct trailer events and tie-ins with General Mills, Old Spice and more. The result was one of the most talked-about family releases of 2026.

Audience Reception

Audiences embraced the film enthusiastically even as critics were more divided — a familiar pattern for the franchise. General moviegoers rewarded it with a strong audience score of roughly 89% on Rotten Tomatoes, while the critical Tomatometer landed considerably lower at around 43%. Commercially there was no debate: The Super Mario Galaxy Movie became one of 2026's biggest box-office successes, posting a massive opening and racing toward the billion-dollar mark worldwide. For most families, the verdict was simple — it delivered exactly the colorful, joyful ride they came for.
