Continuity mistake: When Belloq talks to Indy in the Well of Souls the two Arabs on the left disappear in the angles from Indy's POV.
Continuity mistake: After Indy rips a big strip of Marion's dress in the Well of Souls, it continues to change until she finally gets rid of it on the boat. At some points (eg. running from the plane before it explodes, and other shots) it seems quite straight across, more like a shorter dress than a torn one. A few moments later, when they are crouching behind an earth bank and Sallah tells Indy the Germans are putting the Ark on to a truck, the dress is badly ripped in various places across her back. Not long afterwards, it is in one piece again but back to the bottom edge being ripped. (01:13:00 - 01:21:35)
Continuity mistake: When Indy climbs onto the pontoon of the airplane from the lagoon in the opening sequence, he is obviously wet from swimming in the lagoon. However, in the next scene as he climbs further, his clothes are miraculously dry as observed by watching them blowing freely during take-off. (00:12:05)
Audio problem: When Toht walks in with Dietrich and Gobler, watch the background, you will see Dietrich's lips moving, but you cannot hear him saying anything.
Continuity mistake: Indy looks at the Wurffler through the binoculars. In the next shot, when he takes them off and looks at Katanga, the submarine has moved to the left and astern. (01:34:58)
Other mistake: At the beginning of movie when Indy is about to steal the gold idol, the camera does a close-up of it. The idol has been in a decaying temple for hundreds of years. but it appears shiny and new, as though just placed there. You'd expect the idol to at least be dusty or covered in jungle debris.
Revealing mistake: When Belloq's head explodes, the actor has been visibly replaced by a dummy.
Continuity mistake: During the shooting at the bar, Marion covers her ears to muffle the sound, but a frame later they are around the wall in front.
Continuity mistake: Indy climbs on a plane's wing, and a German mechanic arrives and asks him what he's doing, raising his left arm and ordering him to approach. A shot later, the arm is down.
Continuity mistake: When Indy and Brody meet at the University with the two government officials, a group of rolled maps or plans are placed on a podium horizontally. Halfway through the scene, they are all laying vertically.
Revealing mistake: When the Nazis are about to glow (and die), check the one on our left. His shirt is already unbuttoned right where the light will subsequently glow (which was a mere light bulb). A second later, he triggers a device clutched in his right hand (seemingly a switch) seconds before his chest lights up. (01:47:25)
Other mistake: When Indy and Marion are sealed in the well of souls, they are completely cut off from the outside world. As such, other than the torches, it should be pitch black, but it is surprisingly well lit in there.
Continuity mistake: After Indy steals the idol, while he is hanging in the well, in the front angle his left leg is bent and already outside, in a quite comfortable and secure position; yet in the angles from behind both legs are inside, hanging loose.
Continuity mistake: After the plane takes off in the beginning, Indy sees the snake. His hands are grabbing at it, but a second later his hands are on the rim of his cockpit.
Continuity mistake: When Indy is driving the truck with the ark, a German tries to get in on the right side. Indy kicks the door open twice, and after the second time the top hinge of the door gives easily. The guy is half way dragging on the ground, holding onto the now askew door. Then in the next closeup, the door is hung correctly with the guy on it, and Indy kicks it again. The guy goes dragging again, and then he and the door fall off.
Continuity mistake: There is a shot during the truck chase scene where a Nazi falls out from the back of the truck and goes through the windshield of the car behind it. During the shot from inside the truck, we see two Nazis to the left. The one closer to the camera pushes the other one down. However, in the very next shot, we see that pushed-down Nazi immediately sitting up straight.
Continuity mistake: From the outside, the sides of the hole to access the map room are in shadows, from the angle inside they are sunny.
Continuity mistake: During the truck chase scene, the radiator bars Indy hangs onto keep swapping back and forth from bent outwards to slightly bent with no continuity at all.
Continuity mistake: After grabbing the idol, the cave starts to collapse, filling the place with rocks and rubble. When Indy starts to run, from the angle behind the floor is clean, rocks starting to fall for the first time.
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.
Answer: I also remember this scene. After the ark is sealed, the camera performs a close up of the side of the crate. The stamp reads "Top Secret Army Intel 9906753 Do Not Open" This stamp is burned off just like the swastika is in the scene on the submarine, because in the eyes of God, no nation is holy or worthy enough to claim ownership of the ark. However, this final scene was cut (the burning of the stamp) from the film for a variety of unclear reasons. While it was in theaters, this scene was not included on the DVD version.
Add me to this. We saw the movie in a "pre release" version in Orlando Florida. No advance warning of the movie. We went to see another flick and at the end were "invited" to see this if we were willing to critique it afterwards. This scene was included. I also always wondered why the change.
I also remember seeing this mysterious 'burning' of the logo, most likely it was on a VHS copy of this movie. Yes, it did exist.
I saw it in former Czechoslovakia in the second half of 80's in cinema (west movies came to the east countries' cinemas years later). And I thought it was a great joke that burning out the swastika wasn't just because the Nazis are bad but because nobody is great enough to own the arc. Then after the Velvet revolution I saw the film again on TV (beginning of 90's) and said everyone around: watch it until the end, wait on the post-credit scene, there will be a surprise.
And there was a surprise. The scene was cut off! I was angry on the TV they didn't show the scene. I cannot be influenced by internet discussion or urban legend. The internet didn't exist yet.
I saw it in Portland, Oregon, and was so impressed with the message it carried, that I told friends and we went several times just to see it. Funny thing was when I mentioned it a few years ago, many people said I was a LIAR that it never happened. I could not convince anyone. It was removed because it wasn't Politically Correct. USA is a force for good, God would not burn off AMERICAN TEXT! BUT WE DID SEE IT. Thanks to our Australian eye witness, we know we did not imagine it.
