'Super Mario Galaxy Movie' Teaser Reveals Secret Nintendo Crossover

The Super Mario Galaxy Movie, the follow-up to the 2023 box office smash-hit The Super Mario Bros. Movie, has been teasing several franchise characters in the lead-up to its April 1 release.

Previously, we've seen the introduction of Yoshi, voiced by Donald Glover, one of the long-running game series' most beloved characters. Other, often old-school game characters, such as Bowser Jr., Big Bertha, R.O.B., and Mouser, have made blink-and-you'll-miss-it cameos in promotional material for the movie.
