Brad Pitt and Casey Affleck star in "The Assassination of Jesse James by the Coward Robert Ford," which is presently scheduled for a September release date. But Yahoo! Movies has a slick little teaser trailer that might prove worthy of a look.

"As the charismatic and unpredictable Jesse James (Brad Pitt) plans his next great robbery, he wages war on his enemies, who are trying to collect the reward money - and the glory - riding on his capture. But the greatest threat to his life may ultimately come from those he trusts the most."

Co-starring Zooey Deschanel, Sam Shepard, Jeremy Renner, Mary-Louise Parker, and Sam Rockwell, "Assassination" was directed by Andrew Dominik, whose last film was 2000's "Chopper."
