 Mauldin later re-titled his script Who Discovered Roger Rabbit. Spielberg left the project when deciding he could not satirize Nazis after directing Schindler's List. Eisner commissioned a rewrite in 1997 with Sherri Stoner and Deanna Oliver. Although they kept Roger's search for his mother, Stoner and Oliver replaced the WWII subplot with Roger's inadvertent rise to stardom on Broadway and Hollywood. Disney was impressed and Alan Menken was hired to write five songs for the film and offered his services as executive producer. One of the songs, "This Only Happens in the Movies", was recorded in 2008 on the debut album of Broadway actress Kerry Butler. Eric Goldberg was set to be the new animation director, and began to redesign Roger's new character appearance.
