Continuity mistake: When the baskets are being loaded to be lowered into the Valley of the Lepers, someone loads two heads of lettuce onto a basket. Just as the basket is being lowered, someone else throws in three more heads. When the basket hits the bottom, there are only three heads of lettuce.
Continuity mistake: At the very end, the scaffold that was used to erect the crosses vanishes between shots.
Continuity mistake: Ben Hur's horses change position. When the chariots are preparing for the race and at the starting line, the horse with the pink nose is third from the left, but at the end of the race, the pink-nosed horse is fourth from the right.
Continuity mistake: During the scene when Ben-Hur meets his servant, Simonides, he removes his turban, and his hair is flat and sweaty. The shot pans to his mother, and when it cuts back, his hair is dry and combed.
Continuity mistake: In the parade of chariots before the race, the riders are shown circling the track once before making their way to the starting line. As they emerge from the stables, the horses and chariots leave very noticeable tracks on the ground so you can trace their progress around the track. The riders head down the right side of the track (from the perspective of the stables) then make the wide turn to head down the backstretch, and then make the wide turn back onto the right side of the track where they started. The film then cuts to a wide shot of the riders heading back down the right side of the track for the second time, but the track ahead of them and all the way down the backstretch is now clean of any tracks. It's clear this shot comes from when the riders first emerged from the stables. The riders then stop on the starting line on the backstretch, which means they were either transported to the other side of the track without making a third turn, or they did 1 lap around the track in the space of 1 and a half laps.
Continuity mistake: During the crucifixion, look at Jesus' hands, there are three clear shots of this. In the first shot you plainly see his blood from his hands on the cross. In the second shot, the blood is gone from the cross. In the third shot, it's back.
Continuity mistake: When Ben-Hur is about to be transferred from his cell to Tirus after the tile struck the governor, his hands are being tied by the centurions. When he strikes the incoming centurion, his hands are free.
Continuity mistake: When Jesus Christ is bearing his cross in Jerusalem, in the first shot the sign text on the cross in Latin (and presumably also Hebrew?) is displayed flipped/mirrored/backwards. In the next shot with the sign it is perfectly legible.
Continuity mistake: When the chariot race ends, Messala disappears from the track, only to reappear a shot later.
Continuity mistake: During the chariot race, Judah's chariot has a decorative front metal rail, and in some shots there is a plump curved cushion attached to the rail, on its inner side. It repeatedly disappears and reappears throughout the scene.
Continuity mistake: After the sheik has jumped on the chariot to take control of it, he kicks a man out and one can see the trail behind is empty. However, half a second later, many horses and riders have appeared out of nowhere and are standing right behind the sheik's chariot.
