Cinépolis may have leaked new characters for The Super Mario Galaxy Movie, including Wario and Bowser Jr., suggesting potential team-ups and threats, but this information is unconfirmed and considered a rumor.
Fans are speculating that Charles Martinet, the voice actor for Mario, Luigi, Wario, and Waluigi, may not be returning for the newly announced Super Mario Bros. Wonder and WarioWare: Move It! games. However, despite the lack of official confirmation, it is likely that Martinet will return as the voice of these beloved characters. The speculation has caused some exhaustion among fans, who are more excited about the promising lineup of games announced in the recent Nintendo Direct.
Jack Black, who played Bowser in The Super Mario Bros. Movie, suggested that Pedro Pascal should join the cast in a potential sequel as Wario. Black also stated that it's not a given that Bowser will return for the sequel and that he may need to be turned to help Mario and the rest to defend against some other unseen force of evil. The Super Mario Bros. Movie has received positive reviews, and early box office predictions and a post-credits scene hint that this won't be the last we see of this bunch.
