I believe that this has to be a deleted scene, not a promo picture like those 1,001 shots of jack and/or Ennis posing on or by the truck. (Not that I don't think each and every one of those posed shots are entirely worthwhile, mind you
).
Anyway, Ennis at the Twist plot hasn't been used in any promo that I've seen, and there are very few pics from the scene floating around..... and also it would in a way be giving away the film plot (no pun intended, certainly) too much, which doesn't make sense for promo shots. Plus, it's so
sad, it hurts. So I'm pretty sure it has to be an actual deleted scene.
I've been wondering what Ennis is looking at in that first picture linked to here. Then recently I came across this one:
In the first pic he seems to be looking back towards that little copse of sorry-looking trees. Perhaps it's another crow, hidden in the branches, croaking loudly and ominously, just like when Ennis opened Jack's bedroom window.
We'll never know, of course, unless that elusive special edition DVD with the deleted scenes as bonus material ever materializes. I'm continuing to hope for that to happen.
