Editing Runaway Brain (section)

==Production==
After Disney celebrated [[Mickey Mouse]]'s 60th anniversary in 1988, Mickey starred in the featurette ''[[The Prince and the Pauper (1990 film)|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.<ref name=":0">{{Cite web |last=Taylor |first=Drew |date=October 21, 2021 |title=What happened to Runaway Brain, Disney's lost Mickey short |url=https://www.polygon.com/features/22738384/runaway-brain-evil-mickey-short-streaming |access-date=January 1, 2024 |website=[[Polygon (website)|Polygon]] |language=en-US}}</ref> The director of ''Runaway Brain'', [[Chris Bailey (animator)|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".<ref name=":0" /> Bailey at first saw approval from studio president [[Jeffrey Katzenberg]] and Disney Animation executives [[Thomas Schumacher]] and [[Peter Schneider (film executive)|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''.<ref name=":0" />

Jim Beihold was assigned to layout, Ian Gooding served as art director, and [[Andreas Deja]], who had animated [[Scar (The Lion King)|Scar]] in ''[[The Lion King]]'' (1994), developed the monstrous version of Mickey possessed by Julius based on Bailey's sketches.<ref name=":0" /> [[List of animation studios owned by The Walt Disney Company#Disney Animation France|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.<ref name=":0" /> 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.<ref name=":0" /> 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.<ref name=":0" />
