I just rented this. Written by Nick Cave of all people.
Wasn't terrible. Worth a look if you like westerns, and don't need every single aspect of the story force fed to you.
Ray Winstone is in this, and unless I missed my mark here, he is using a Ruger Vaquero with birds head grip.
In 1880.
Had some other interesting guns in it too. It wasn't really a gun person type movie though. It was chatty, and kind of slow. But very stylistic and visually interesting for sure.
The same fellow who directed this did The Road which I think looks pretty damn good.
