Fifteen actors from the Lord of the Rings trilogy are suing New Line Cinema for breach of contract, claiming they're still owed a percentage of an estimated $100 million US in profits from sales of movie merchandise, their lawyer said Wednesday.

The New Zealand actors were supposed to split five per cent of the revenue after expenses from sales of caps, video games, mugs and other merchandise, says the lawsuit filed May 30 in Los Angeles County Superior Court. The suit contends New Line breached the contract by taking distribution and gross participation fees to which it wasn't entitled.

The fees weren't in the contract and they ate up all the profits owed to the actors, said their lawyer, Henry Gradstein of Los Angeles.

With those fees, "the expenses will always be approximately 104 per cent. It's Hollywood accounting," Gradstein said.

The merchandise has brought in $100 million US in net profits, including $22 million US just for items associated with Paul Norell, who played the King of the Dead, the lawyer estimated.

New Line does not comment on pending litigation, spokesman Robert Pini said Wednesday.

It's not the first suit against New Line associated with the hugely successful movie series.

Director Peter Jackson's production company sued the distributor two years ago, claiming it was shortchanged on profits, including revenue from DVD sales, for 2001'sThe Fellowship of the Ring.

In 2005, New Line reached an out-of-court settlement with Hollywood producer Saul Zaentz, who claimed he was owed an additional $20 million US in royalties from the Lord of the Rings films. Terms were not disclosed.
