Corrected entry: At one point in the movie, they say Charlie shot a prize cow in the head 6 times and that it is a miracle that it is still alive. If you are counting when he shoots the cow, there is 1 shot, then 2 more, then 6 more. That makes 9 shots to the cows head, not 6.
Corrected entry: When Hank goes shopping for the supplies, a bottle of booze and the dildo, Charlie shows it to Irene and then places it back in the trunk. In the next scene they are seen pushing the car over the cliff into the water with the supplies in the trunk. Later that night in the hotel room, Irene has the bottle of booze on the night stand and we see the dildo the next morning.
Corrected entry: When Charlie shoots the cow, he seems to use a revolver, yet we hear the shells hit the ground after each shot.
