Jack Black Showed Up to a Tokyo Press Event in a Full Bowser Onesie — and Honestly, We’d Expect Nothing Less
Jack Black has never been one to half-commit to a bit. But showing up to a photo call in Tokyo wearing a full Bowser onesie? That’s a level of dedication that even the Koopa King himself would respect.
The actor, who voices the villain Bowser in the animated Super Mario franchise, turned heads at an event for The Super Mario Galaxy Movie on March 26, 2026. While most Hollywood stars arrive at international press events in tailored suits and careful composure, Black rolled in dressed head-to-toe as his fire-breathing character — and looked like he was having the time of his life doing it.
Black wasn’t alone in the costume department. Keegan-Michael Key, who voices Toad, also showed up fully in character. Key paired his iconic mushroom hat with a decked-out suit featuring all the Super Mario characters, delivering a look that was equal parts dapper and delightfully absurd.
The rest of the Mario Bros. cast was also on hand for the Tokyo event, including Chris Pratt (Mario), Charlie Day (Luigi), Donald Glover (Yoshi), Anya Taylor-Joy (Princess Peach) and Benny Safdie (Bowser Jr.). The Super Mario Galaxy Movie is the sequel to the 2023 hit The Super Mario Bros. Movie.
This isn’t the first time Black has gone all-in for his Bowser role. In the 2023 film, he delivered what became one of the movie’s most unexpectedly viral moments: a love ballad called “Peaches,” performed by Bowser in a desperate serenade to Princess Peach, voiced by Taylor-Joy.
The song — in which Black sings little more than “Peaches” over and over again for the hook — became a genuine cultural moment. And the music video? It’s racked up over 72 million views on YouTube. The video features Black in a Bowser-inspired costume tinkling the ivories on a peach-colored piano in a peach-colored room, while occasionally gazing at a framed photo of Princess Peach. It’s absurd, earnest and completely irresistible.
Black even performed the single live at The Game Awards 10-Year Concert at the Hollywood Bowl shortly after the first Super Mario movie premiered, cementing “Peaches” as more than just a movie gag — it became a legitimate concert moment.
Here’s the part most people don’t know: Black didn’t just sing the song as written. He transformed it.
“Jack Black is an incredible singer and musician, so we spent a night writing the song and sent the demo to Jack,” The Super Mario Bros. Movie co-director Aaron Horvath said, according to Insider. “A couple [of] days later, Jack sent us back a finished track. He had added his own twist on it and his pianist played an original music track for it. We were blown away.”
That detail reveals something about why Black’s Bowser works so well. He doesn’t just lend his voice to the character — he inhabits it, reshapes it and clearly has a blast doing so. Whether that means rewriting a love ballad in a couple of days or suiting up in a onesie for a press event on the other side of the world, the commitment never wavers.
With The Super Mario Galaxy Movie heading toward release, Black’s Tokyo appearance signals that the sequel’s promotional tour is shaping up to be every bit as entertaining as the first. If the 2023 film proved anything, it’s that audiences don’t just show up for the animation — they show up for moments exactly like this.
And if Black has another musical number tucked inside the sequel? The internet might not survive it.
