I found a script from 2003 online and I saw a scene that wasn't in the final movie. It's an unused scene from the Twist Ranch. You know how Ennis has a flashback during the reunion of seeing Earl's body? Well during the unused scene while talking to Jack's father, Ennis appears to have another, but as the camera pans up, he doesn't see Earl, he sees Jack.
How scary is that? I'm glad this went unused, I don't think I could have coped

the tire iron scene was bad enough
