Continuity mistake: As Mr. Fletcher is riding up on horseback to greet Lady Ashley, you can see him riding up next to a parked, red truck, that has the front end pointed away from the house. Keep an eye on that truck, because it will have the front end pointing towards the house, as Fletcher gets closer to Lady Ashley. (00:27:50)
Continuity mistake: In Kate's hotel room, when she's trying to get away from GW she steps backwards through the hotel room's doorway onto the porch, and falls straight through the broken wood railing, but when GW looks down at Kate on the pile of hay, there's now a window behind GW, not a doorway, and clapboard siding has suddenly appeared on the hotel wall as well.
Visible crew/equipment: As Ennis leaves for his first fishing trip with Jack, Alma is holding Alma Jr, whose pajama shirt is lifted. Alma Jr's microphone wire is visible on her stomach. (01:08:45)
Continuity mistake: Near the end when they're entering the Mexican village, Billy's coat disappears as he rides through the gate. (01:17:45)
Continuity mistake: During the ambush on the river two Indian braves can be seen firing arrows one gets shot and dies but the brave who is left his hair and clothing are wet. The scene cuts away and when it cuts back to this brave he stands up only to get shot in the heart. He clutches his heart with both hands and then dies by falling into the river but now his clothes and hair are completely dry. It's clear that the earlier part was a retake after he fell in the river.
Continuity mistake: In the scene where the wagon train is waiting for Wagonmaster Harlow to decide which fork in the road to take, all the shadows are to the left. As they approach Harlow, the shadows are in front and moment later when the wagons move off the shadows are to the right. (00:26:20)
Visible crew/equipment: During the attack on the town, right after Jake breaks Percy's hand to get out of the cuffs and begins kicking the wagon door we see an exterior shot of two people running and just before one does a flip, film crew is visible on the left. We see at least two people sitting in chairs, one wearing a bluish short sleeve shirt, shorts, and boots, and another in a white shirt wearing a baseball style cap. We also see a blue light coming off their equipment. (00:35:30)
Revealing mistake: When Potter starts shaving at the morning of the Indian attack on the wagon train, his mirror falls off the post, and as he bends down to retrieve it, an arrow embeds itself right above his head. If you look closely in that scene, you can see a length of targeting wire used to guide the arrow sticking to the post above Potter's head. (00:37:10)
Continuity mistake: When Hiram, Juan and Kelly first see Old Fred's wagon in the distance, the white tarp on it is draped across it and down one side. When they arrive at it, it's draped differently. They also arrive at it from the side, when they were approaching from straight in front on it. (00:46:15)
Continuity mistake: After Isaiah kills a bear, Otter Bob holds out a bottle of liquor at him. In the close-up, Bob is holding the bottle by the neck. In the wide shot, he's holding it by the body.
