Work continued on the screenplay from late 2003 onwards, taking place in the small bungalow where Groening first pitched "The Simpsons" in 1987. The writers spent six months discussing a plot, and each of them offered sketchy ideas. Jean suggested the family rescue manatees, which became the 2005 episode "The Bonfire of the Manatees", and there was also a notion similar to that of "The Truman Show" where the characters discovered their lives were a TV show. Groening rejected this, as he felt that the Simpsons should "never become aware of themselves as celebrities", but the idea was later used in the video game "The Simpsons Game". Groening read about a town that had to get rid of pig feces in their water supply, which inspired the plot of the film. The decision for Flanders to have an important role also came early on, as Jean wished to see Bart wonder what his life would be like if Flanders were his father. Hank Scorpio, a character from the 1996 episode "You Only Move Twice", was originally meant to return as the main antagonist, but the staff dropped the idea and created Russ Cargill instead. Having eventually decided on the basic outline of the plot for the film, the writers then separated it into seven sections. Jean, Scully, Reiss, Swartzwelder, Vitti, Mirkin, and Meyer wrote 25 pages each, and the group met one month later to merge the seven sections into one "very rough draft". The film's script was written in the same way as the television series: the writers sitting around a table, pitching ideas, and trying to make each other laugh. The script went through over 100 revisions, and at one point the film was a musical. However, the songs were continually being shortened and the idea was dropped. Groening described his desire to also make the film dramatically stronger than a TV episode, saying that he wanted to "give you something that you haven't seen before".
