Runaway Brain

On a dark and stormy evening, Minnie Mouse arrives at Mickey Mouse's house to find him playing a Snow White and the Seven Dwarfs video game and becomes angry over Mickey having forgotten about the anniversary of their first date. Mickey then comes up with the last-minute idea to take her to a miniature golf course and shows her a newspaper ad for it, but she instead notices another ad for a trip to Hawaii, which costs nine hundred ninety-nine dollars and ninety-nine cents, and misinterprets it for the gift. After Minnie leaves, Mickey panics over how he can make enough money for the trip when Pluto shows him the want ads and Mickey sees an ad from Doctor Frankenollie to earn the amount of money that he needs for "a mindless day's work". Upon arriving at Frankenollie's residence, Mickey is dropped down a trapdoor into the scientist's laboratory, where he reveals his plan to switch his donor's brain with that of his enormous Pete-resembling monster, Julius. The experiment causes an explosion that takes Frankenollie's life, but it is a success, nonetheless, as Mickey and Julius' brains are switched.

In his new body, Julius finds Mickey's wallet and notices a photo of Minnie, whom he instantly becomes smitten with. He escapes from the laboratory and finds Minnie while she is shopping for swimsuits. After Minnie immediately mistakes Julius for Mickey, the latter arrives to save her, but Minnie becomes terrified of him due to the appearance of Julius' body and panics, until Mickey convinces her of who he is and places her on the top of a skyscraper for safety. As Julius continues to pursue Minnie and a battle between him and Mickey occurs, they land on a telephone line and become electrocuted, sending their brains back into their proper bodies. Continuing their fight at the skyscraper where Minnie is, Mickey manages to subdue Julius using a billboard advertising the trip to Hawaii there and save her. Mickey and Minnie eventually travel to Hawaii together on an inflatable boat pulled by Julius, who is goaded by Mickey into chasing after the photo of Minnie in his wallet.

After Disney celebrated Mickey Mouse's 60th anniversary in 1988, Mickey starred in the featurette The Prince and the Pauper, which was directed by George Scribner and released in theaters with The Rescuers Down Under in 1990. The Rescuers Down Under however failed at the box office, so a new project was sought for the character.^[3] The director of Runaway Brain, Chris Bailey recalled: "If you were a director or part of the development, if you were between assignments, you were asked to develop Mickey shorts".^[3] Bailey at first saw approval from studio president Jeffrey Katzenberg and Disney Animation executives Thomas Schumacher and Peter Schneider regarding the rework of an idea he had for a Roger Rabbit short, Tourist Trap, with Mickey and Donald Duck heading on a vacation and Donald attempting to kill Mickey, but after a failed storyboard screening, Bailey received permission from Roy E. Disney to develop another short idea, Runaway Brain.^[3]

Jim Beihold was assigned to layout, Ian Gooding served as art director, and Andreas Deja, who had animated Scar in The Lion King (1994), developed the monstrous version of Mickey possessed by Julius based on Bailey's sketches.^[3] Disney Animation France, who was just finishing A Goofy Movie (1995), was given the animation job. While the crew was in France, Katzenberg left Disney, leaving Bailey without one of the executives who most supported his ideas.^[3] While the first screening of the mostly completed short to the executives was successful, Schumacher and Schneider went on to order many changes that would cut scenes and require others to be newly animated.^[3] These included not having the monstrous Mickey drooling, toning Mickey's electrocution to be more cartoonish, and having the ending with Julius chasing an "effigy Minnie" made of pillows replaced with having him pursue the wallet picture.^[3]

The beginning of the cartoon shows Mickey playing a satirical take of fighting games such as the Mortal Kombat franchise and the Street Fighter series, with Dopey and Queen Grimhilde in her peddler disguise from Snow White and the Seven Dwarfs (1937) fighting each other. Director Chris Bailey said that Jeffrey Katzenberg was the one who suggested a scene with a video game, and Bailey came up with the fighting game after his idea of a first-person shooter based on Bambi (1942) was rejected.^[4] The general plot of the cartoon refers back to Mary Shelley's Frankenstein, with Doctor Frankenollie and Julius being heavily inspired by the titular character and his monster. The composite name "Frankenollie" comes from the names of animators Frank Thomas and Ollie Johnston, who were two of Disney's Nine Old Men.^[5]

Mickey's wallet contains a photo of him from Steamboat Willie (1928). In addition, Mickey whistles the short's primary theme, Steamboat Bill, before he is dropped down into Frankenollie's laboratory and a Polynesian-styled rendition of it is also played in the credits.^[5] The wallet also features a library card from the fictional 'Guillard County Library', a reference to Stuart Gillard.

The Exorcist (1973) is referenced in the shot where Mickey first arrives at Frankenollie's residence, with the imagery mirroring Father Merrin's arrival at Regan MacNeil's house.^[5]

Zazu from The Lion King franchise briefly appears twice, once when Mickey is dropped down into the lab and again when Julius roars at him.^[5]

One of the objects seen during Mickey's descent into the lab is a pink slip with "J.K." on it. This is a reference to Katzenberg, who left Disney in 1994 and went on to form rival studio DreamWorks with Steven Spielberg and David Geffen.^[5]

In terms of general reception, the macabre nature of the animation's plot brought criticism from some Disney fans due to the contrast with the previously light tone of Mickey Mouse cartoons. Andy Mooney, then chairman of Disney's consumer products unit, remarked to the Los Angeles Times in 2003 that "the very fact that Mickey was possessed was very disturbing" to some audiences, though the character "overcomes that".^[1]

The film was screened out of competition at the 1996 Cannes Film Festival.^[6] It was first released in North America on August 11, 1995, alongside theatrical showings of A Kid in King Arthur's Court, then on September 12, 1996, with The Hunchback of Notre Dame in Australia and on October 18, 1996, attached to A Goofy Movie in the UK. The short was to be re-released with 101 Dalmatians, which was sent to theaters with the short attached in 1996, but Disney asked theater owners to cut the short off all film prints and replace it with trailers for then upcoming Disney films.^[7] In addition, the short was released with theatrical screenings of George of the Jungle in 1997.^[8][9]

The cartoon was nominated the Academy Award for Best Animated Short Film at the 68th Academy Awards, ending up losing to A Close Shave starring Wallace and Gromit.^[2]

The short was released on May 18, 2004 on Walt Disney Treasures: Mickey Mouse in Living Color, Volume Two: 1939-Today.^[10]

It is also available as a Movies Anywhere-exclusive digital download with the Walt Disney Animation Studios Short Films Collection (but is not included on the Blu-Ray/DVD disc set).^[11]
