Charlie Day, the voice of Luigi in The Super Mario Bros. Movie, says he would be more than happy to return if Luigi’s Mansion ever gets its own animated spin-off. The actor recently shared his enthusiasm for Nintendo’s spooky side-series, which puts Luigi, not Mario, at the center of ghost-hunting adventures. While Day said he has no confirmation that such a movie is in development, he made it clear he loves the idea. A Luigi’s Mansion film could offer a darker, funnier, and more atmospheric take on the Mushroom Kingdom universe. For fans, that makes this possibility especially exciting.
