Woody Allen impression. The staff felt the voice was too distracting, so Castellaneta re-recorded Norton's dialogue with a different voice. Isla Fisher and Erin Brockovich also recorded cameos, but their scenes were cut. Kelsey Grammer recorded lines for Sideshow Bob, who was to appear at several different points, but these scenes were also cut. Johnny Knoxville was also touted as a possible guest star. Although he does not provide the voice, Arnold Schwarzenegger is president of the United States rather than then-President George W. Bush because, according to Groening, "in two years ... the film [would be] out of date". Brooks was nervous about the idea, noting that "[Schwarzenegger's] opinion polls were way down", and has said that they "were [hoping] he'd make a political comeback". The animators began by drawing an accurate caricature of Schwarzenegger, but one of the staff instead suggested an altered version of recurring character Rainier Wolfcastle as President. This idea was developed, with the design of Wolfcastle, himself also a caricature of Schwarzenegger, being given more wrinkles under his eyes and a different hairstyle. Editing Every aspect of the film was constantly analyzed, with storylines, jokes and characters regularly being rewritten. Although most animated films do not make extensive changes to the film during active production due to budget restrictions, The Simpsons Movie crew continued to edit their film into 2007, with some edits taking place as late as May, two months before the film was released. James L. Brooks noted, "70 percent of the things in [one of the trailers]—based on where we were eight weeks ago—are no longer in the movie." Matt Groening said that enough material for two more films was cut. Various new characters were created, and then cut because they did not contribute enough. Originally Marge was the character who had the prophetic vision in church. The writers however considered this to be too dark and it was changed to Grampa. The role of Lisa's love interest Colin was frequently revised. He was previously named Dexter and Adrien, and his appearance was completely altered. One idea was to have Milhouse act as Lisa's love interest, but the writers realized "the audience was not as familiar with [his] long-standing crush on [Lisa] as [they had] thought". A car chase in which Homer throws flaming mummies out of a truck at the EPA was replaced with "more emotional and realistic" scenes at
