At the end where Rudd has his gun up to his sister, Alice's head, the pistol isn't cocked, but in the next scene his pistol is now cocked.
After Rudd shoots the gang member with the mask that was caught in the next county, The Dead man's eyes move when John moves his head .
When John is sitting on the bridge drinking you will see that he drinks all the contents in the bottle. When he throws it up in the air to shoot, liquid suddenly appears in the bottle.
The western era is not real at all. It is Hollywood made.
When Alice walks into the area where John is being jailed, you can see the Phillip's screws in the doorknob plate. Phillips screws were not invented until about 1930.
