Continuity mistake: At Molly's party after returning from Europe, the Duchess is introduced, and everyone bows. The shot shows Molly reaching for her neighbor who's standing straight, to bow down, and she does. Then there is a long shot showing the crowd, and the neighbor is again standing, and then you see Molly reach out for her again as she just had.
Continuity mistake: When the Bannister gang begins shooting at the house, the ladies abandon their breakfast to run and hide upstairs. There's a pitcher half full of milk on the table. But a few shots later, when one of the Bannisters bursts into the kitchen, the milk pitcher is empty, and the dishes are in different positions on the table. (01:23:55)
Continuity mistake: As Jesse, Diamondback and Homer try to black out the windows on their car (to protect themselves from the sunlight) Homer spray paints the window next to him black. The camera angle switches to a wide shot as the car drives by. At this time, the back window (which was just blacked out) has not been spray painted yet. It is totally clean again.
Continuity mistake: When Chino ambushes Morrel's men in the mountains he is waiting on a pointy rock. When the camera angle changes there are bushes behind him that weren't there before. (01:27:05)
Continuity mistake: After Pierce Brosnan does the deal for the bullet, Anjelica Huston rides off with his horse attached to her carriage. Only problem is we see the entire exchange, and at no point does anyone tie the horse on.

Continuity mistake: During the cemetery scene a wide shot shows the Tetons in the background almost cloud covered, and a few minutes later as everyone leaves the funeral to fight the fire, the wide shot shows the mountains clear.
Continuity mistake: At the end of the town collapse, a sincerely drunk Ben dives head-on into a tub where a lady (in her underclothes?) is just enjoying a bath. Propelled by Ben's momentum the tub with both passengers slides down the slippery planks and splashes into the river, while Ben rearranges himself into a comfortable sitting position between shots. If I wasn't completely mistaken also the lady changes her outfit, since the embroidery is missing when they float along. (02:23:35)
Continuity mistake: When Wyatt Earp is playing cards, a man comes to the table and pounds his fist saying, "You have to listen to this, Marshal." The stacks of money on the table are knocked over by the impact. The camera then looks at only a head shot of Wyatt's disturbed expression at the man bothering him. When the camera looks at the table again, the money is properly stacked again, all within a few seconds.
Continuity mistake: In this scene we see Laura shot by a arrow. The arrow hits her in the right upper chest just below the neck. In the next shot they cut out the arrow and it's very clear the arrow has moved to the top of the right shoulder near the collar bone.
