The Villain
The Villain mistake picture

Other mistake: Handsome and Charming head out of Snakes End (followed by the newlyweds) and begin their long journey. It then cuts to Cactus Jack before he begins the journey, and at the start of this shot as he places Whiskey's bit, we can see the signpost with three wooden arrow signs and the hillside behind him. This is the same location where Cactus Jack lays trap number seven, named "the tunnel in the hillside," on the next day during the journey; noticeable when Handsome and Charming arrive. (00:28:35 - 00:54:45)

Visible crew/equipment: In a scene where Kirk Douglas appears to 'leap' onto his horse, a crew members arm is clearly visible in the foot of the shot pushing a mini trampoline next to the horse, ready for Kirk to jump onto and bounce up onto the saddle.

Continuity mistake: Cactus Jack's leather cowboy boots have block heels and spurs with rowels and jingle bobs. In quite a few shots throughout the movie, Jack's boots change to no-heel flat soles, and the spurs are missing, though we still hear the distinctive jangling of Cactus Jack's spurs.
