1. Their names aren’t Mario and Luigi Mario
According to the authoritative guide to all things Mario – MushroomKingdom.net – the script called for the Mario Bros. to have a last name. The characters were never given names in the game series and the producers decided that because they were the Mario Bros., their last name must be Mario. According to the site, creator Shigeru Miyamoto was quoted in Game Informer as having “laughed rather loudly” when he heard this info.
2. Princess Daisy is not the ruler of the Mushroom Kingdom
Princess Daisy, first introduced in the Game Boy’s Mario Land, does not rule the Mushroom Kingdom; she’s the leader of Sarasaland. Luigi isn’t even present in the game, though he later develops a relationship with her as Mario and Peach’s counterparts.
3. The Mario Bros. naturally jumped high, without the need for special boots
The weird jump boots in the movie really had nothing to do with Mario games. Also, Big Bertha is a fish in the game, not an actual woman.
4. Goombas are not reptiles of any kind
We’re not sure why the goombas were made to be tall reptilian-like creatures when they’re literally living mushrooms gone bad.
5. Bowser isn’t a lizard creature; he’s a turtle
While Dennis Hopper made a believable Bowser, King of the Koopas, sadly, he isn’t a lizard. Bowser has been confirmed to be an evil turtle with a spiked shell.
