I don't care what anyone says,
Super Mario Bros was an awesome movie.
You can bag on it all you want about it "not being faithful" or something, but in 1993? We didn't have a very established "persona" for Mario yet. The only time I ever heard him speak was in the Super Mario Bros Super Show with Captain Lou Albano's voice. Personally I think Lou Albano was a
*fantastic* voice for Mario. Mario's not supposed to be this Italian Mickey Mouse they've turned him into once the Nintendo 64 came out. He's supposed to be a plumber (or carpenter if you wanna get picky, so let's just say handyman) from Brooklyn, New York. I don't know how many New Yorkers you've ever heard, but they definitely don't sound like "It's-a me, Mario!" Bob Hoskins is a British actor, but he got the middle aged New York handyman persona down perfectly in this movie.
Now imagine if you were given the task of making a live action movie about two plumber brothers who get warped to an alternate dimension with a lizard-man overlord, mushrooms everywhere and a kidnapped princess. This concept sounds insane. There's basically no real plot to take from the games, only tons of bizarre imagery.
Given the task the film crew had with this project, it's no surprise it had such trouble with re-writes in production. But somehow... somehow... they came up with a wacky adventure that's a lot of fun to watch. Look at how many subtle references to the video games are jam packed into the background signs. Even the big lady wearing red was named Big Bertha (like the big red predatory fish in SMB3). If you have a mushroom kingdom, you need a king right? Well having the mushroom king be this creature who devolved into a sentient fungus was a perfect way to allow for "mushroom power ups" to happen. Even Mario's trademark high jumping was accounted for with the jump shoes.
I'm astonished how people could possibly think the movie wasn't true to its source material. The whole thing is loaded with clever ways to bring the insanity of the Mario franchise into a "real life" movie. When I saw it in theaters as a 9-year-old, I thought it was great. And to this day I still do.
