Nintendo and Illumination have just released the first full-length trailer for The Super Mario Galaxy Movie, the sequel to the 2023 smash-hit video game adaptation, which grossed $1.3 billion at the box office.
The trailer for the new movie, slated for release on April 1, sees brothers Mario (Chris Pratt) and Luigi (Charlie Day) in a new, intergalactic adventure — but not without some friends in tow.
The new footage features the Mario Bros meeting Yoshi for the first time—a first for the film adaptations, but a face familiar to any Mario fan, as a beloved character and constant presence in the game franchise.
Other fan favorites appearing in the trailer include Birdo, Big Bertha, T-Rex, Tostarenan, as well as Rosalina, voiced by Brie Larson. There is one new addition, however, that may have slipped by unnoticed, with a blink-and-you’ll-miss-it cameo from an old-school character.
‘The Super Mario Galaxy Movie’ Marks Mouser’s First Major Return in Decades
Mouser can be spotted next to Princess Peach (Anya Taylor-Joy) towards the end of the new trailer. The anthropomorphic mouse sports a pair of sunglasses as the two face off with Birdo.
For those unfamiliar with the vintage character, Mouser was a boss who first appeared in the 1987 Japanese Mario game, Yume Kōjō: Doki Doki Panic, rebranded in the West as Super Mario Bros. 2 in 1988.
Canonically, however, Mouser has been dead in the franchise since then — kind of. Since his defeat at the hands of Mario in Super Mario Bros. 2, he has made mostly appearances via an archival image only. For example, Super Mario Bros. & Friends: When I Grow Up (1992), gamers merely receive career info about him, or in Super Smash Bros. Brawl (2008), he’s seen as only a sticker.
Mouser’s made a few throwback appearances as a boss in the 90s games Super Mario Bros. All-Stars (1993), Super Mario All-Stars + Super Mario World (1994), and BS Super Mario USA (1996). If you wanted to get nitpick-y about it, Mouser does appear in the 2001 Game Boy Advance game Super Mario Advance. However, the old-school boss has not made a major, original appearance since the ’90s, and even then, the gameplay was rooted in his original ’80s appearance.
Whether Mouser will have a voice actor or just be a mere visual cameo is still unknown, as is his future in the Mario franchise. Fans will have to wait until April to see this new generation of the character.
