The studio that made The Lord of the Rings trilogy is being sued for $20m (£11m), according to a Hollywood paper.
Saul Zaentz owns the rights to the Rings books after making a cartoon of them in 1978, and let New Line Cinema film them for a share of the profits.
He claims they haven't given him as much cash as he's owed, and he's also asked for $700,000 in damages.
The Rings films have made $2.9bn (£1.6bn) worldwide. The Return of the King won a record 11 Oscars this year.
