As sheriff Ed Tom Bell, he risked death in the fight for justice, pursuing Javier Bardem's psychotic murderer across the desolate and lawless landscape of west Texas.

Now Tommy Lee Jones is taking his love for the letter of the law a step further _ albeit for more self-serving reasons.

The veteran actor is suing the makers of No Country For Old Men for US$10 million ($15 million), which he claims he is owed for his role in last year's award-winning crime thriller.

The film, about a botched drug deal and its brutal repercussions, was adapted from a Cormac McCarthy novel of the same name.

Directed and co-produced by the brothers Joel and Ethan Coen, it was a critical and box-office hit, earning more than US$160 million and going on to win three Baftas, two Golden Globes and four Oscars, including best picture, best director and best supporting actor for Bardem.

Jones has filed his lawsuit in San Antonio, Texas.

Jones, who won his only Oscar for his role alongside Harrison Ford in 1993's The Fugitive, claims he has not been paid the bonuses he was promised and his initial fee for appearing in the movie was unjustly reduced.

He also claims that a contract was given to him despite the fact that it contained several inaccuracies.

The 61-year-old says he signed a contract with NM Classics on April 3, 2006, agreeing to act in the film and to provide "additional related services" for promoting the movie.

In return, the legal papers allege, the company agreed it would pay Jones a fixed "upfront" fee and, depending on its success, "significant box-office bonuses and `back-end' compensation".

The vagueness of those promises has returned to haunt the actor. His lawyers claim he was promised "significant" bonuses to compensate him for his reduced fee.

No Country For Old Men was a co-production between Paramount Pictures and Miramax Films, with Paramount largely controlling the film's release and distribution outside the United States.

Jones demanded that he, the Coens and the film's producer, Scott Rudin, should be entitled to the same treatment and equal shares of the box-office spoils.

But the lawsuit claims that in December, barely a month after the film was released in America, Paramount executives told Jones his contract contained a "mistake" related to "a major issue involving the deduction for home video expenses".
