Duck are dueling on pianos, some heard Donald call Daffy a "goddamn stupid nigger", rather than the scripted "doggone stubborn little". Legal issue Gary K. Wolf, author of the novel Who Censored Roger Rabbit?, filed a lawsuit in 2001 against The Walt Disney Company. He claimed he was owed royalties based on the value of "gross receipts" and merchandising sales. In 2002, the trial court in the case ruled that these only referred to actual cash receipts Disney collected and denied Wolf's claim. In its January 2004 ruling, the California Court of Appeal disagreed, finding that expert testimony introduced by Wolf regarding the customary use of "gross receipts" in the entertainment business could support a broader reading of the term. The ruling vacated the trial court's order in favor of Disney and remanded the case for further proceedings. In a March 2005 hearing, Wolf estimated he was owed $7 million. Disney's attorneys not only disputed the claim but also said Wolf owed Disney $500,000–$1 million because of an accounting error discovered in preparing for the lawsuit. Wolf won the decision in 2005, receiving between $180,000 and $400,000 in damages. Proposed sequel Spielberg discussed a sequel in 1989 with J. J. Abrams as writer and Zemeckis as producer.

With human Ritchie Davenport, Roger travels west to seek his mother, in the process meeting Jessica Krupnick (his future wife), a struggling Hollywood actress. While Roger and Ritchie are enlisting in the Army, Jessica is kidnapped and forced to make pro-Nazi German broadcasts. Roger and Ritchie must save her by going into Nazi-occupied Europe accompanied by several other Toons in their Army platoon. After their triumph, Roger and Ritchie are given a Hollywood Boulevard parade, and Roger is finally reunited with his mother and father, Bugs Bunny. Mauldin later retitled 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
