The production staff had considered a film adaptation of "The Simpsons" since early in the series. The show's creator, Matt Groening, felt a feature-length film would allow them to increase the show's scale and animate sequences too complex for the TV series. He intended the film to be made after the show ended, "but that [...] was undone by good ratings". There were attempts to adapt the fourth season episode "Kamp Krusty" into a film, but difficulties were encountered in expanding the episode to feature-length. For a long time the project was held up. There was difficulty finding a story that was sufficient for a film, and the crew did not have enough time to complete such a project, as they already worked full-time on the show. Groening also expressed a wish to make "Simpstasia", a parody of "Fantasia"; it was never produced, partly because it would have been too difficult to write a feature-length script. Recurring guest performer Phil Hartman had wished to make a live-action film based on his character Troy McClure; several of the show's staff expressed a desire to help create it, and Josh Weinstein proposed to use the plot of the 1996 episode "A Fish Called Selma" for the film, but the project was cancelled following Hartman's death in 1998.
