Revealing: While Clint Eastwood is walking into a saloon (or maybe a jail) you can see the cameraman and director's shadow on the ground.

Revealing: Near the end, Clint Eastwood is sneaking up on a house at night. The old guy (Ed Begley Sr) shoots at Eastwood repeatedly until his gun is empty as Eastwood dodges from tree to tree. Just before running directly to the house, there is a strange black circle that completely covers Eastwood for a few seconds. It is very obvious and no reason why it should be there.

Continuity: During the opening credits, when titles are appearing under Eastwood's swinging feet, you'll see the footage of the swinging feet reverse itself at least twice.

Revealing: Towards the end of the film when the old guy (Ed Begley Sr) is shooting a rifle at Clint Eastwood, the thumb of his left hand is on the top of the barrel, preventing him from seeing the front sight.

Visible crew/equipment: In the scene where the judge is releasing Clint Eastwood and telling him that his story checks out he calls him over to the window to watch a hanging. As the guards walk down the scaffold steps on the ground under the gallows there is a pile of rope and next to the rope is a modern electrical box of some type. It's silver with with louvers (vents) in it.

Revealing: In the second hanging scene (with the speech of the whisky) Clint Eastwood is looking at the judge's window and he sees him watching. If you look at the window, you will she a big shiny circle over it, probably from the flashlight.
