Bob Hoskins and John Leguizamo were so drunk on the set of Super Mario Bros. that Hoskins broke his finger.
The big-screen adaptation of the classic video game ended up a critically panned box office disaster, and it seems everyone knew that would be its fate very early in production. So according to Leguizamo’s autobiography, the onscreen Mario and Luigi spent a lot of their days dipping into Hoskins’ scotch to make the experience less interminable.
Unfortunately, during one take, an inebriated Leguizamo was behind the wheel of their characters’ van (not a good idea!) when he hit the gas too fast and the door closed on Hoskins’ hand, breaking his finger. If you look closely, you can see that Hoskins wears a cast on his finger at times in the movie.
