 James L. Brooks chose Hans Zimmer to compose the film 's score , as they were good friends and regular collaborators . Zimmer felt that the score was a " unique challenge " , and he had to " try and express the style of The Simpsons without wearing the audience out " . He used Danny Elfman 's original opening theme , but did not wish to overuse it . He created themes for each member of the family . Homer 's leitmotif was a major focus , and Zimmer also composed smaller themes for Bart and Marge . Regular television series composer Alf Clausen was not asked to score the film , noting : " sometimes you 're the windshield , sometimes you 're the bug " .
