Bob Hoskins

From the Super Mario Wiki

“The worst thing I ever did? Super Mario Brothers. It was a fuckin' nightmare. The whole experience was a nightmare. It had a husband-and-wife team directing, whose arrogance had been mistaken for talent. After so many weeks their own agent told them to get off the set! Fuckin' nightmare. Fuckin' idiots.”
—Bob Hoskins, "The Guardian" interview

Robert William "Bob" Hoskins, Jr. (October 26, 1942) is an Academy Award-nominated English actor. He portrayed the live-action version of Mario seen in the movie Super Mario Bros., which was released in 1993. However, although he played Mario, the actor who played Luigi, John Leguizamo, got a larger role.

Bob Hoskins did not know Super Mario Bros. was based upon a video game; Hoskins only learned the film was based upon a video game when his son informed of this and showed him the actual game.
