Continuity mistake: After the Baxter/Rojo dinner, the background changes from nightime to daytime at the cemetery, then back to nightime again when Clint kidnaps Mirasol.
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 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: When we see a close-up of the meter, there is a box saying "10 Centavos for One Hour." The words were not in the box in the previous shot.
