Crowe told The Associated Press on Friday that a script based mostly on the eleventh novel of Patrick O'Brian's 20-novel series, The Reverse of the Medal, had been written, but that discussions were at a very early stage.

"There's still a long way to go," the New Zealand-born actor told AP at a cricket match between England and Australia in London. He said talks had been taking place with the owner of the rights to the novels.

The 44-year-old Crowe, who won a best actor Oscar for his starring role in Gladiator, is a keen cricket fan. His two cousins, Jeff and Martin, are former captains of the New Zealand national team. Jeff is now a senior cricket official and is in charge of the team of officials at the England-Australia match.

The AubreyMaturin novels consists of 20 books and one partly written before his death in 2000 by O'Brian, all set during the Napoleonic Wars.

The 2003 movie Master and Commander took material from several of the novels. The Reverse of the Medal, published in 1986, sees Aubrey in the Caribbean in his ship HMS Surprise, where he meets his illegitimate son Samuel Panda, a Catholic priest born from an illicit liaison.

Crowe gave no indication of when filming could start but said it was one of a number of projects he is considering.
