In October 1991, Allers signed on to co-direct King of the Jungle alongside its initial Director George Scribner. Allers brought on board Brenda Chapman, who would become the head of story. Afterwards, several of the lead crew members, including Allers, Scribner, Don Hahn, Chapman, and production designer Chris Sanders, took a safari trip to Hell's Gate National Park in Kenya, in order to study and gain an appreciation of the environment for the film. After six months of story development work, Scribner decided to leave the project, as he feuded with Allers and the producers on their decision to turn the film into a musical, as Scribner's intention was to make a documentary-like film more focused on natural aspects. Following Scribner's departure and dissatisfied with the original story, Allers along with Hahn, Sanders, Chapman, and Beauty and the Beast Directors Kirk Wise and Gary Trousdale conceived a new story outline for the film over the course of two days in February 1992. In April 1992, Allers was joined with Rob Minkoff who was assigned as co-director, and the title was changed to The Lion King.
