Continuity mistake: When Corporal Allen pulls Private Hitch off the ramparts when Hitch is shooting at Zulu's in the hills with his pith helmet on backwards, Hitch gets shot in the leg, and Allen pulls him in. Allen is shot in the chest, he clutches his chest, falls inside ramparts with blood underneath his clutching hand. When you see him after camera cut he is clutching the OTHER side of his chest.
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.
