Ok , before I write this , I realize that some people might think I'm looking a bit too deep, maybe I'm a little off my rocker, but I think I see a subliminal message in one of the scenes. Stop your DVD on the scene where Ennis is leaving the Twist house with the shirts. Its a full view scene of the house and sky and foreground, when Ennis is looking back at Jack's window. The name JACK is spelled out subliminially. The right side of the windshield of Ennis's truck makes the "J" . The roof of the house makes the "A". The cloud above the peak makes the "C" ( this is what first got me going on this idea, it seemed odd) and lastly the large tree to the right of the house makes the K, although you have to fill in the botton right leg of the letter. Like I said it's subliminal, so check it out if you don't believe me.
