Continuity mistake: When Curly Bill is shooting up the town while drunk, he fires about 10 more rounds than his six shooter can hold without reloading (so too many shots even if he had a second gun), and still has a round remaining when he shoots Marshal Fred White. In the 1880 court hearing held after Marshal White's death, Curly Bill still had 5 rounds remaining in his pistol.
Continuity mistake: At the beginning, when the president lands in the helicopter, the shots go back and forth between the rotors spinning, and the rotors stopped. (00:02:10)

Continuity mistake: In the scene where Gilbert and his buddy's are eating in the cafe. The first time you see the undertakers bowl of cereal, it keeps changing from full to empty several times.
Continuity mistake: Crawl is thrown into the manure pile and his hat falls off. Then Theo throws the pitchfork at him and the top tine makes a hole in his hat. Watch the shot closely: the tine on the fork at the top of the screen definitely makes a hole. Later in the day, there in no sign of the hole. Even in the next scene when Crawl is feeding the pigs, the hole is not there. And I can tell you from experience that a pitchfork tine leaves a hole big enough to notice.
Continuity mistake: During one of the piano lessons, Baines tries to force Ada to lie on the bed next to him. When she tries to leave, he holds her back, pulls her blouse down about the shoulders, and it tears in the back. When she gets up later, the blouse is whole again. (00:52:05)

Close inspection shows the clip chamber is empty (not loaded), and a cartridge clip is positioned beside the weapon in its tailored slot in the custom case. Maggie closes the case and says, 'I don't understand.' After Bob explains what she is to do, then leaves, Maggie opens the case again and suddenly there's a clip in the weapon (loaded) and another one beside it. The weapon was not loaded when she looked the first time.
Continuity mistake: When Madonna has her legs wrapped around Willem Dafoe in the parking lot sex scene, in one shot she is looking down at him with a sly smile as if to say she's enjoying it; the very next shot she's got her head up looking as if she's in an excruciating amount of pain.

The shot was meant to be at the end of the 1950s. There's also a motorway in the background with lots of fast moving traffic.
