Lord of the Rings director Peter Jackson is suing the studio that financed the trilogy. “In his lawsuit, Mr. Jackson claimed that New Line committed fraud in its handling of the revenues generated by 2001’s “The Fellowship of the Ring,” and as a result, he was underpaid by millions. The suit does not specify a damage award. But in an interview last week, his lawyers said that, after New Line applied its contract interpretation from “Fellowship” to the other two movies, Mr. Jackson was underpaid by as much as $100 million for the trilogy.”
