Ethan Shanfeld Not much is known about Nintendo’s upcoming “Super Mario Bros.” movie, but Keegan-Michael Key revealed to Variety that his character Toad has a musical moment in the film. When asked if Toad shows off his singing chops in the animated movie, Key said, “He does. I got to improvise a song in ‘Super Mario Bros.,’ which was an absolute blast. That was just a stick of fun, that whole thing.” Regarding Toad’s voice, Key said, “I was working on the voice with my partner and trying to find the voice through the internal journey of the character. And then with the directors [Aaron Horvath and Michael Jelenic], we sprinkled some things in, we moved it around.”
