The writers had written the opening concert scene without a specific band in mind. Green Day were cast in that role having requested to guest star in the show. Tom Hanks also appears as himself in the film and accepted the offer after just one phone call. "Everybody Loves Raymond" creator Philip Rosenthal provides the voice of the father in the "new Grand Canyon" commercial with Hanks. Due to time restraints, several guests who had recorded parts were cut from the film. Minnie Driver recorded the part of a patronizing grievance counselor in a scene that ended up being cut. Edward Norton recorded the part of the man who gets crushed as the dome is implemented, performing a 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.
