I just heard about this clip through the Onion's AV Club, so I thought I'd share it with all y'all. Essentially someone has taken clips from Sergio Leone's Once Upon A Time In The West and matched it to the Arcade Fire track "My Body Is A Cage." They mesh pretty well. I should mention, however, that the clip contains spoilers, so if you were planning on watching the movie (though I doubt you were) you might not want to check this out. Either way, enjoy.
