List of Super Mario Bros. (film) deleted scenes

These are original designs of characters, and early scripts from the Super Mario Bros. film. The original running time of the film was of 2 hours and 10 minutes; to reduce the estimated PG-13 rating, it was cut by 30 minutes, losing many subplots, action scenes, and instances of character development in the process.

Deleted scenes
Only referenced on the earlier screenplays, the climax of the film was supposed to be longer and much more complex. It was supposed to include dimensions merging, Goombas getting caught between walls and making them explode, buildings fusing with one another, and facing off with King Koopa on the Brooklyn Bridge in the middle of this chaos. He sets up the Bob-Omb, while Koopa would fully de-evolve into a Tyrannosaurus Rex/Human hybrid, grabbing him by the neck, raising his head and roaring in victory, only to have the Bob-Omb fall in his mouth, blocking his throat, and making him fall off the Bridge, exploding in little bits once as he hit the water. It was, allegedly never shot due to budgetary issues.
 * The original Dinosaur prologue, which was cut and replaced by an animated intro, narrated by Dan Castellaneta.
 * Extra shots of Koopa chasing Daisy's mother on the intro.
 * The Mario Brothers at the Riverfront Café, where they find Scapelli plumbers, losing their job in the process.
 * An alternate scene of Luigi meeting Daisy in the Riverfront Café. Daisy accidentally breaks all the dishes that were being carried by a waiter, but Luigi steps in and pays for the damages while assuming fault.
 * Mario and Luigi preparing for their date. In this scene, it is mentioned that Daniella's full name is Daniella Pauline Verducci. There is also the Family Pride subplot.
 * An alternate introduction for King Koopa. Not much is known about this scene.
 * Many scenes involving the Missing Brooklyn Babes, one of them featured in the Making of the Super Mario Bros., where one of the girls offers a cigarette to a Goomba.
 * Mario and Luigi discussing Family Pride, again, in the Prison Cell.
 * One of the most notable scenes to be deleted from the film was the scene of who was transformed into slime in the De-vo Chamber. Many were chosen to be de-evolved, such as Toad, a Goomba, Simon, and one of the Technicians, but no one is certain about who exactly was de-evolved.
 * A whole subplot involving Koopa's slow de-evolution throughout the film. This scene was better explored in earlier drafts of the film.
 * A longer Car Chase scene. Not much is known about these scenes other than a few shots present on the trailer, ranging from reaction shots to cars crashing into one another.
 * Iggy and Spike's rap on the Boom Boom Bar.
 * Mario bouncing in the Fungus Trampoline while Luigi hangs by his belt on the hook in the Elevator Shaft. This scene was supposed to give closure to the Family Pride subplot.
 * Alternate scenes of Lena handing Koopa the rock, only to have him later ditch her for Daisy because she is a Princess.
 * An entire sequence featuring Mario getting chased by Goombas on Koopa's Tower, after Daisy tells him where Daniella is.
 * After the Goombas break in the room where the Missing Brooklyn Babes were, a Goomba walks up to the pipe entrance, and from there it cuts to the Slide scene.

Concept art
An early clay sculpture showcased what the film would have been like, with realistic Warp Pipes and a checkerboard-pattened path for Mario and Luigi to follow. Some concept art initially showcased that King Koopa was originally going to be played by Arnold Schwarzenegger, who would wear armor based on Bowser's artwork. There were also some more humanoid concepts for the Koopa King, including a version wearing samurai-like armor. Goombas were apparently going to be more like humanoid mushrooms rather than de-evolved foot soldiers. Toad was also going to be a humanoid similar to his game counterpart. Koopa Troopas would have appeared as humanoid turtles, but were cut. Piranha Plants, Thwomps, and Hammer Bros. would have also appeared, but were also cut. An early design for the Bob-omb resembled its counterpart from Super Mario Bros. 2, while Yoshi would have resembled a juvenile T-Rex.

Original story
In an interview with Mark McCoy, designer of the movie, McCoy released an early script of the movie-the original script was much different from the one that remained. The unused script has a character known as Doug that does not make the final cut and the scene where Mario and Luigi meet Daisy was changed. There is also another unused script from 1991 written by Tom S. Parker and Jim Jennewein. This 1991 script is more fantasy based and is closer to the video game, having more elements from the game than the actual version: King Koopa kidnaps a princess named "Hildy", and makes her his bride so he can get the Crown of Invincibility, so now Mario and Luigi, along with their friend Toad go on an adventure to save Hildy. Then a few hours later, Toad betrays the Mario Bros. and goes to work for Koopa, but then he started having regrets about the mistake he did, and redeems himself near the end. The copy of this script can be bought from Scriptfly.com.

Fire Snakes were originally written into the desert sequence of the Super Mario Bros. film, but were cut for unknown reasons. Scripts state that they "[...] resemble moray eels, their mouths filled with pointed piranha-like teeth," and that "[t]hey gnaw through the skin, burrow into the body cavities, and lay their larvae. It can take weeks for the host to die."
