The Walt Disney Co. may have to pay the author of the book behind the 1988 movie Who Framed Roger Rabbit? as much as $400,000 after a jury said the company underreported some merchandise sales.

The jury in state court in Los Angeles Monday sided with Gary Wolf's claims that Disney had underreported about $2 million in sales of Roger Rabbit merchandise at Disney stores and theme parks. Lawyers for Wolf and Disney disagreed about how much the company might have to pay Wolf under the verdict.

Including money the jury awarded for additional merchandise sales, Disney owes Wolf about $180,000, Marty Katz, a lawyer for Disney said in a telephone interview. Wolf's lawyer J. Larson Jaenicke said in a telephone interview that the total amount is about $400,000.

Wolf created Roger Rabbit and other Toontown characters in his 1981 book Who Censored Roger Rabbit?
