Anyone ever see this one? Made in 2006, it has Duvall driving some horses to Wyoming in the late 1890s when he encounters 5 Chinese girls being taken to a brothel in an Idaho mining town.
I saw the second half of it on IFC a couple times so I investe $10 in a DVD from e-Bay. Great story. Highly recomended. Mature theme, 18 years and up probably.
At the end, they add tidbits that make you wonder if it was based on a true story. Probably not but some aspects based on actual events.

Two of the bad guys - Fender and Big Ears - are about the meanest looking bad guys I can recall in a movie. Both guys look sorta big and tough in other photos, but they invest a believable amount of menace in these roles.
