The Wizard is a movie that was released in 1989 as an advertisement for Super Mario Bros. 3, and the Power Glove. It was reviewed by The Angry Video Game Nerd along with SMB3. Overall it wasn't really anything more than a 90 minute commercial, so an opinion wasn't really given. But according to the Nerd, all the kids in the theater didn't particularly care about the plot, they just cared about the games.
A boy and his brother run away from home and hitch cross country with the help of a girl they meet to compete in the ultimate video game championship.
