The Super Mario Galaxy Movie Release Date, Cast and Games

The Super Mario Galaxy Movie: Release Date, Cast, and Connection to the Games

The Super Mario Galaxy Movie is the animated follow-up to 2023’s The Super Mario Bros. Movie, made by Nintendo and Illumination. Nintendo’s announced theatrical release date is April 1, 2026, in the United States, with Japan scheduled for April 24, 2026. Release dates vary by country, so the U.S. date shouldn’t be treated as a worldwide launch date.

The sequel brings back Mario, Luigi, Peach, and Bowser while expanding the cast with Rosalina, voiced by Brie Larson; Bowser Jr., voiced by Benny Safdie; and Yoshi, voiced by Donald Glover. Those additions make the Galaxy connection especially interesting, although the official announcements don’t establish that the film follows the games’ story beat for beat.

Here’s what the official information establishes, how the movie connects to Nintendo’s games, and what to check before planning a viewing.

The Super Mario Galaxy Movie Release Date

Nintendo’s March 10, 2026 announcement gives the following theatrical schedule:

Universal Pictures is handling worldwide distribution. That doesn’t mean every market receives the film on the same day: the announcement specifically distinguishes the U.S., Japan, and other territories.

There’s also a reason you may encounter a different U.S. date. Nintendo’s September 2025 title announcement originally listed April 3, 2026. The later March announcement specifies April 1, so that is the date to use when referring to the announced U.S. schedule.

These are announced release dates, not confirmation of current screenings at a particular cinema. For a booking decision, check the film’s listing with your local theater, especially outside the United States.

Is It a Sequel to The Super Mario Bros. Movie?

Yes. Nintendo describes The Super Mario Galaxy Movie as following the 2023 film, rather than as an unrelated reboot or a separate live-action adaptation.

The returning creative team also connects the two productions:

• Aaron Horvath and Michael Jelenic return as directors.
• Matthew Fogel returns as screenwriter.
• Brian Tyler returns as composer.

Those credits are listed in Nintendo’s official production announcement.

For viewers, the useful distinction is that this is a continuation of Nintendo and Illumination’s animated Mario film series. The word Galaxy signals an expansion into another part of Mario’s world, not a replacement of the first film’s central cast.

Should you watch the first movie beforehand?

Watching The Super Mario Bros. Movie first is the clearest preparation. It introduces this version of Mario and Luigi, the Mushroom Kingdom, and the principal characters returning for the follow-up.

That’s a viewing recommendation, not a claim that the sequel is impossible to understand on its own. The supplied official announcements don’t establish how much background knowledge its story requires.

If you’re choosing between replaying a game and watching the first movie, the first movie is the more directly relevant starting point for the film series. The games provide additional character and setting context.

The Super Mario Galaxy Movie Voice Cast

The announced English-language voice cast combines the first film’s principal actors with several additions:

Nintendo announced the returning principal cast in its September 2025 release. Its November 2025 announcement identified Larson as Rosalina and Safdie as Bowser Jr., while the March 2026 update added Glover, Rae, and Guzmán.

This table refers to the announced English-language performances. Localized versions may have different voice casts.

Rosalina and Yoshi are confirmed—not just fan theories

Two particularly useful answers for anyone following early speculation are straightforward:

• Rosalina is in the movie, voiced by Brie Larson.
• Yoshi is in the movie, voiced by Donald Glover.

What the casting announcements don’t establish is how much screen time either character receives or precisely how they fit into the story. A confirmed character appearance isn’t confirmation of every theory about that character’s role.

How Does the Movie Connect to Super Mario Galaxy?

The title and Rosalina’s inclusion provide a clear connection to the Super Mario Galaxy games. However, Nintendo’s official wording describes the film broadly as being based on the world of Super Mario Bros. It does not establish a scene-by-scene adaptation of the original game.

That distinction matters because a Mario movie can borrow characters, locations, and ideas from several games while telling its own story.

What the original game contributes

Released for the Wii in 2007, Super Mario Galaxy takes Mario beyond the Mushroom Kingdom into a space-based adventure. Its defining ideas include small planets, shifting gravity, star-filled environments, and Rosalina’s connection to the Lumas and the Comet Observatory.

For readers unfamiliar with the game, that’s the essential context: “Galaxy” points toward Mario’s cosmic adventures, rather than simply another journey through familiar Mushroom Kingdom locations.

Rosalina is especially significant because she is closely associated with that part of the series. Her confirmed presence gives the movie’s title a concrete character connection. It doesn’t, by itself, confirm that her game storyline will be reproduced in the film.

The cast reaches beyond one game

The announced characters also suggest a broader selection of Mario material:

• Rosalina is closely tied to Super Mario Galaxy.
• Honey Queen appears in Super Mario Galaxy.
• Yoshi has a prominent playable role in Super Mario Galaxy 2, as well as a long history elsewhere in the franchise.
• Bowser Jr. appears across multiple Mario games, including the Galaxy titles.
• Wart is associated with Super Mario Bros. 2, rather than originating in Galaxy.

That mix is a good reason not to assume the title identifies the film’s only source. It supports a more cautious reading: the sequel draws on the wider Mario universe while giving Galaxy-associated characters a place in its cast.

It does not prove that specific game levels, boss fights, power-ups, or story sequences appear. Those details need their own evidence.

What Is the Movie About?

The official announcements establish the sequel’s identity, cast, and production team, but the material cited here doesn’t provide enough detail for a reliable full plot summary.

The safest spoiler-free description is that The Super Mario Galaxy Movie continues Nintendo and Illumination’s animated Mario series and introduces characters associated with Mario’s cosmic adventures, alongside figures from other parts of the franchise.

Beyond that, it’s important to separate three kinds of information:

1. Officially announced facts: the title, cast, filmmakers, and theatrical schedule.
2. Promotional material: characters and events presented in trailers.
3. Interpretation: predictions about the larger story, character motivations, or how closely it follows a game.

A trailer can establish that a character appears in the marketing. It doesn’t necessarily explain that character’s complete role or reveal the order in which events happen.

For that reason, detailed fan summaries shouldn’t be treated as an official synopsis unless they point to a source that actually supports them.

Where to Watch The Super Mario Galaxy Movie

The release described in Nintendo’s announcement is theatrical, with Universal Pictures distributing the film worldwide.

For practical viewing information:

• In the U.S., use the announced April 1, 2026 date as the release reference, then check local cinema listings for screenings.
• In Japan, the announced date is April 24, 2026.
• Elsewhere, check the local distributor or cinema listing rather than assuming either date applies.

The announcements cited here do not establish a streaming premiere date, a digital rental or purchase date, or subscription availability. Those are separate release stages and shouldn’t be inferred from the cinema schedule.

If you’re looking specifically to watch at home, look for a listing that names the film, your country, and the access type. Included with a subscription, available to rent, and available to buy are different offers. A service carrying the first Mario movie also doesn’t automatically establish that it carries this sequel.

Where to Find the Official Trailers

Nintendo has published an official trailer and a final trailer. Its official movie page brings together promotional material and cast information.

These are useful starting points if you want to distinguish genuine footage from fan-made trailers or speculative edits.

If you prefer to know as little as possible, skip the final trailer and stick to the cast and release information. Even official marketing can reveal characters, locations, and set pieces you might rather discover in the film.

The Bottom Line

The Super Mario Galaxy Movie is the official animated follow-up to The Super Mario Bros. Movie, with an announced U.S. theatrical date of April 1, 2026, and a Japanese date of April 24, 2026. Rosalina, Bowser Jr., and Yoshi join the returning principal characters, giving the sequel connections to both the Galaxy games and the wider Mario series.

The key expectation to keep in check is the adaptation itself: the title confirms a Galaxy connection, not a promise to retell the 2007 game exactly. Watch the first movie for film-series context, use Nintendo’s trailers for official previews, and check local listings for where and when you can see the sequel.
