An interview between The Guardian and Bob Hoskins, the actor who portrayed Mario, says that the movie was a nightmare for him. Here is what he had to say about it:
"The worst thing I ever did? Super Mario Brothers. It was a f***in' 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! F***in' nightmare. F***in' idiots."
