Martinet's Second Role
Not content with one cameo, Charles Martinet also voices Mario and Luigi's dad in the film. It's a much more disguised performance than his Giuseppe cameo, so most people miss it completely on their first watch.
The Super Mario Bros. Movie
A Brooklyn plumber named Mario travels through the Mushroom Kingdom with a princess named Peach and an anthropomorphic mushroom named Toad to find Mario's brother, Luigi, and to save the world from a ruthless fire-breathing Koopa named Bowser.
