The movie in question is none other than 1993's infamous "Super Mario Bros." Starring Bob Hoskins, John Leguizamo, Samantha Mathis, and Dennis Hopper, the "Super Mario Bros." movie took a simple side-scroller and turned it into a post-apocalyptic alternate dimension where dinosaurs have evolved into what are essentially humans. Gone are the bright, shiny worlds of the source material, instead replaced by a sprawling and decaying city on a planet where most of the natural resources have been consumed. Hopper played the role of President Koopa, who plans to invade our reality with "de-evolution guns" that have a striking similarity to the Super Nintendo's Super Scope.

Although according to Rotten Tomatoes the movie was savaged at the time of its release, it later went on to gain a cult-like status (per The Strand).

In an interview with Conan O'Brien in 2008 (via YouTube), Hopper recounted his regret with an anecdote involving his child by saying, "I made a picture called 'Super Mario Bros.,' and my six-year-old son at the time — he's now 18 — he said, 'Dad, I think you're probably a pretty good actor, but why did you play that terrible guy King Koopa in 'Super Mario Bros.?' And I said, 'Well Henry, I did that so you could have shoes.' And he said, 'Dad, I don't need shoes that badly.'"

At least even after all of those years, Hopper still had a sense of humor about his time on "Super Mario Bros."
