Continuity mistake: In the scene where Indy is telling about the Staff of Ra, the background color of the blackboard changes between shots. It looks like there are some chalk residues (after the blackboard has been washed) in one of the shots, but not in the other.
Continuity mistake: When Indy and the German driver crash through the villager's construction ladders the truck is missing the Mercedes-Benz hood ornament that appears in every other shot.
Continuity mistake: Just after Indiana (barely) escapes the tumbling boulder at the beginning of the movie, he leaps through a veil of spider webs, only to be held up by the native hunters and Belloq, who takes the idol from Indiana. Watch carefully - there is a thick strand of webs attached to the idol as Indy hands it to Belloq, but they disappear in the next shot as Belloq hefts the idol and holds it up in the air.
Continuity mistake: The 'Top Secret' sign is put on the crate across vertically laid planks. A shot later the sign appears slanted across horizontally laid planks. Though it could be argued that there could be a second sign on the opposite side with horizontal planks, when the warehouse guy turns left to store the crate, we get a glimpse of the left side and it's not painted.
Continuity mistake: In the scene where Sallah and Jones are in the Well of Souls where they are putting the sticks in the Ark to left it up. Notice Sallah stick, when he first puts it in, on the stick are no tassels. But when they both left at the same time Sallah same stick that he put in has tassels on it.
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: The fight scene in Marion's bar clearly shows Indy using an automatic pistol to shoot at the bad guys. You can see the slide lock open when he runs out of ammo. But when the scene switches he is holding a revolver. Then when the huge guy is strangling Indy and the German says, "Shoot them, shoot them both." Indy is once again holding an automatic.
Continuity mistake: As Indiana writes "Neolithic" on the blackboard in his classroom at the beginning of the movie, he stops and checks to see if he's spelling it right, then finishes writing it. Later shots of the board reveal the same word on the board, only either the handwriting is different or the actual structure of the word has changed.
Continuity mistake: In the map room, Indy pulls out a notebook and takes off the elastic band. The elastic goes flying away. Moments later he closes the book and the elastic is in his hand. Also, the elastic starts off being pink (the one that flies off), then blue (the one that he puts back onto the book) and ends as tan coloured when he puts the book back in his pocket.
Continuity mistake: At the beginning of the film, When Indy uses the whip to take the guides gun away, Satipo makes a weird face and starts to move away in amazement. The very next frame, in a wider shot, he is not finishing his movements, but on the contrary he is standing still, with a normal gesture, until a second later he starts to repeat the movement and looks from before.
Continuity mistake: After Satipo runs with the idol, Indy grabs a root to help him climb up the ledge. Half a second later, from a different angle, the root is meters away and he is grabbing it again, repeating the whole scene.
Continuity mistake: Just before the car carrying Marion in the wicker basket explodes in the alley, Indiana shoots a man twice in the chest. The man has blood stains on his shirt before he is shot.
Continuity mistake: As Indy and Marion are starting to run from the plane, you can see the yellow wheel chocks are back in place under the plane's tires.
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 hitting one thug, Indy jumps out of the way of one trying to spear him, leading to the one behind Indy getting run through. As the guy gets run through, he is in front of a hanging string of fruit, with the stacked fruit to his right. After a cut scene to Indy and Marion running away, the run through thug is now facing the fruit stand, setting up the sight gag of the blade sticking out with two fruits stuck on it.
Continuity mistake: While Indy is in the Well of Souls, Belloq greets him and is standing by one of the four sides of the rectangular hole. A frame later he stands by one of the corners.
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: Satipo drops the whip half a meter away from the closing gate, then runs away. However, when Indy rolls underneath the door, the whip is laying right next to it.
Continuity mistake: When Indiana is hiding his face with the cloth, watch as he enters the tent that Marion is being held prisoner in - at first, Indiana has to hold it in place; in the next shot, he has it tucked into the rest of the folds. The next shot, the actual position of the cloth changes.
Continuity mistake: After Indy replaces the idol for a bag filled with sand, the position of the bag changes between frames.
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.
