Variety says a deal is being negotiated for Damon to play Polo, who ventured farther into Asia than any Westerner before him. His journey took 24 years, during which Polo became a confidante of Kublai Khan and witness to many technological advances of China and Mongolia.

Monahan also wrote Tripoli, the story of how U.S. soldier William Eaton joined forces with an exiled king to overthrow the corrupt ruler of what is now Libya. Ridley Scott is attached to direct.

The buff star of action flicks including The Bourne Identity has been dating Barosso for 12 months since he met the aspiring interior designer at the Miami bar where she worked.
Since then, Barosso has travelled the world with the 34-year-old actor, staying with him in Europe during the filming of Ocean’s 12 and even travelling Down Under late last year for the premiere of The Bourne Supremecy.

A friend told American gossip mag Us Weekly the pair were engaged but “it’s all very hush, hush”.

Damon’s spokesperson has refused to confirm or deny the reports.

Damon has been linked to several Hollywood stars in the past including Winona Ryder and, most famously, Minnie Driver, who heard news of the couple’s break-up via the Oprah Winfrey show.

But, after the media circus surounding good pal Ben Affleck and Jennifer Lopez, Damon told the Sunday Telegraph Sunday Magazine last year that he was sworn off celebrity romances and now only dates “civilians”.

The original, released by 20th Century Fox, centered on two couples who head off to Colorado for skiing and dirt biking. Along the way, they witness a satanic sacrifice, but when they call the local authorities, all evidence disappears. They resume their vacation but find themselves shadowed by a cult.

Peter Fonda and Loretta Swit starred in the original.

The film is being updated for the production outfit Regency Enterprises by writers Drew McWeeny and Scott Swan.

Moore had been partners in the LivePlanet production venture with Affleck, Damon and Sean Bailey. Among Moore’s producer credits are the “American Pie” movies, the “Project Greenlight” movies, “Joy Ride” and Affleck and Damon’s breakout hit “Good Will Hunting.”
