The Assassination of Jesse James by the coward Robert Ford
If your looking for a high-action western, don't watch this movie. If your looking for a beautifully shot, wonderfully acted retelling of the last days of Jesse James life, then this is the movie for you. I guess the best way to describe the movie is haunting.
You know what's coming, it's in the title, but you go to a point of rooting for Robert Ford, to rooting for Jesse James. Happy that he's finally dead, and then somehow sad. It's a movie that despite the fact it contains VERY little action, you can't take your eyes off of. The entire movie is set up as a build-up and what it's building up to doesn't disappoint.
Some truly amazing performances by both Brad Pitt and Casey Affleck (yes, there IS an Affleck who can act). Sam Rockwell rounds out the cast in yet another amazing character performance. I didn't even realize it was him until 3/4 of the way through the movie.
If you like psychological movies, I recommend this. If you like westerns, I recommend this. If you like well made movies that don't have to blow stuff up to be good, I recommend this. It's truly a great-piece of film making.
