Continuity mistake: In the submarine dock of Geheimhaven, Captain Mohler is a man with dark hair in his mid or late thirties. But during the procession, he seems to be much older, with grey hair.
Continuity mistake: When the temple collapses, Satipo is crouching looking at the chaos. Indy starts to run and there's a wide angle of the passage ahead but Satipo is nowhere around. He couldn't have managed to run that distance in half a second.
Suggested correction: He had a couple of seconds to run away from that spot.
Visible crew/equipment: As the bad guys are leaving the dig site for Cairo, there is a shot of the black vehicle (lead car) looking right at the driver. On the bottom of the shot is a shadow of film equipment that shouldn't be there. The shot lingers, so the shadow is very visible. (01:22:50)
Continuity mistake: In the shot after Belloq's death, the generator and the rock Indy and Marion are on disappear.
Continuity mistake: When Marion arrives on the deck of the Bantu Wind, Dietrich turns to look at her. Katanga is in the background, behind the colonel. But, just before Marion hits Dietrich, Katanga appears on the opposite side from where he was and catches Marion. (01:36:00)
Continuity mistake: While the Holy Fire is killing the soldiers, in a shot of two soldiers being hit by the light, the stone wall is missing in the background of the scene. (01:47:30)
Continuity mistake: As Dietrich and Gobler come into the tent, Toht's leather case can be seen already opened. In the next shot, the case is suddenly closed.
Continuity mistake: In Hangar 51, the size and position of the text in the Ark's box changes between shots.
This is not the same mistake as the one you listed. Yours speaks about the style of the box (that changes from vertical planks to horizontal planks). Mine speaks about the size and position of the text.
Mine is about the box and the text "The 'Top Secret' sign is put on the crate across vertically laid planks. A shot later the sign appears slanted." Yours is a duplicate.
Continuity mistake: Over Belloq's left shoulder and behind Toht, a soldier stands next to a klieg with a machine gun. In the next shot, the soldier's gun has disappeared. (01:44:25)
Continuity mistake: During the procession, after Indy hides behind the box, Captain Mohler can be seen walking with the soldiers behind the Ark. In the next shot, he's walking in front of the Ark.
Continuity mistake: When Indy abruptly brakes the truck and the Ark box slides backwards, the poles on either side of the box disappear for the rest of the chase.
Continuity mistake: After the kliegs and generator explode, there is a shot of Belloq and Toht on the altar. Belloq has the ivory rod in a vertical position. In the next shot, the rod is horizontal.
Continuity mistake: When the two soldiers place the Ark on the altar, they move to the walls of the canyon, and Toht stands next to Belloq. A few shots later, the soldiers are next to the Ark's poles (where they will be in the next shot), and Toht seems to be very huge. (01:44:39)
Visible crew/equipment: Just before the shooting starts at The Raven, you can see that Otto's shadow movements do not match the German's movements. Also, when Marion fights with Toht, behind her you can see the shadow of a man with short hair and no hat moving to the left (Indy still has his hat on during this scene).
Continuity mistake: Dietrich and Gobler walk forward to stand next to Belloq while he's saying, "Once again, Jones..." In the next shot, Gobler has disappeared (this can be spotted by the distance between Belloq and Gobler's foot in the first shot). (01:10:57)
Continuity mistake: When Indy runs over the sergeant, the background behind the truck changes between shots, going from the desert to a mountain. (01:28:45)
Continuity mistake: When the Nazis are aboard the Bantu Wind, in the full scene of the ship deck, Toht stands behind Belloq. But, after Marion tries to hit Dietrich, the camera focuses on Belloq, then on Dietrich again. Toht is not seen anymore on the deck.
Continuity mistake: In the canyon, in the shot of Toht, just before Belloq says "Do as you will", everyone in the background (Marion and her two guards, Dietrich, some soldiers) is gone (taking as reference the giant stone behind Belloq and the characters' positions in the previous and next shots). (01:43:49)
Continuity mistake: As Gobler's jeep is returning to the road after being hit by Indy, Gobler's goggles move from his eyes to his cap between shots.
Continuity mistake: At the beginning of the Truck Chase, when Billy Horrigan starts shooting at Indy, Reg Harding's right hand goes from grabbing the front passenger seat to grabbing the metal bar of the jeep between shots. (01:23:28)
