Continuity mistake: In the chapel, before Indy turns the chalkboard over to explain the staff of Ra and the medallion to the G-men, the chalkboard goes back and forth from tilting forward to tilting backward a few times.
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.
Factual error: There's absolutely no way Sallah and Indy would be able to lift that 'lid' (for lack of a better word) off the ark. That thing is solid rock and would weigh close to a metric ton - and none of them look like professional deadlifters to me.
Continuity mistake: When Toht frees Marion, Dietrich enters the tent, and a few seconds later, Gobler does the same. In the next shot, Gobler enters first, and Dietrich second. (01:07:52)
Continuity mistake: When Belloq and the Germans are at the Well of the Souls, a top-down view shot when Indy yells, "Why don't you come on down here and I'll show you!" shows Belloq and a German soldier kneeling down to the left of him, also looking down into the hole. But, the side view shots show only Belloq standing near the opening.
Continuity mistake: When Indy is listening to the one Army agent he is in the process of putting his right hand into his pocket. In the next shot the hand is back on the leather case. (00:16:46)
Continuity mistake: When the Cairo Henchman pulls the knife on Marion, the blade edge changes position from down to up to down again.
Revealing mistake: During the big car chase where Indy follows the ark, he comes down a hill on a horse to get into the truck. You can tell the ground has already been disturbed by the horse from previous takes.
Revealing mistake: After the German is chopped up in the propeller and the plane explodes, you can the blasting cord exploding along the path to the explosion.
Continuity mistake: When Indy sits down in the seat of the plane look behind him, there is nobody holding a Life magazine or fitting the description of the man later shown watching him from the other seat.
Continuity mistake: During the truck chase, as Indy is fighting with the German driver, they knock over some scaffolding and a man drops down in front of the windshield. None of the workers on the scaffolding landed on the truck, much less the front of it. So, he shouldn't have been there.
Other mistake: In the opening scene Indiana is with horses and scouts. A few minutes later he is running for his life and in a few moments he's at a waiting plane. Why does he need scouts and horses for the cave is in walking distance from the plane and how did the scouts and horses get there?
Character mistake: Watch the extras playing the Cairo civilians walking around just before the big swordsman reveals himself to Indy. Several of them are just aimlessly walking back and forth as if they have no idea where to go.
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.
