The Magnificent Seven (1960) - 5 mistakes

Continuity: McQueen and Brynner take a hearse up the hill to deliver a coffin to the graveyard. When they go back down the hill, you can see a plume fall off one of the horses' heads, but in the next shot, the plume is back on.

Visible crew/equipment: When the three Mexican farmers arrive in town you see the traces in the street from a car making a 3-point-turn in the front of the picture. You see the traces in later shots, too.

Continuity: During the hearse sequence, the duo passes the large red circular sign with the "5" in the center (first time code). They then progress to the General Store (the next-to-last two-story building) and Horst Buchholz waves them off. When Yul turns and says "I don't think so," they're passing the red nickel again (second time code).

Continuity: Near the beginning when Eli Wallach and his gang pillage a Mexican village, an angry farmer runs at Eli with a machette but gets shot twice. There are no bullet holes or blood on the farmer until later shots where you can see blood stains on his back.

Continuity: When Chico's (Horst Buchholz) hat is shot off, it falls behind him. He takes three running steps to his right to get behind the wall, and his hat is there, within reach of his rifle barrel.
