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: As Indy and Satipo enter the temple, When Indy says to Satipo "stop" he is holding the whip in his right hand, yet when Indy says "stay out of the light" the whip is in his left hand. (00:05:10)

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.

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: During the scene where Indy and Marcus are with the Army intelligence agents, watch the agent who is wearing the light blue suit - at the moment when Marcus refers to a secret chamber, the agent in the blue suit has his right hand resting on top the chair that he is sitting on, but in the next shot when he replies "secret chamber" his right hand is now on his face. (00:17:55)
Continuity mistake: When Indy is packing his suitcase to go to Nepal, he picks up a gun that is wrapped in a piece of cloth, he tosses the gun with his left hand into his right hand and begins to unwrap the gun from the cloth by raising his right hand, so that the gun will fall into his left hand, but the gun ends up falling into Indy's right hand instead of his left hand. (00:22:10)
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: During the middle of the bar fight scene, Indy was slammed on the counter and whispered to the girl, "Whisky". In the next shot she grabbed the bottle and handed it to Jones. The very next shot she hands him the bottle again. It happens very quick. Watch carefully. (00:32:05)
Continuity mistake: When Belloq grabs the machine gun, his left hand is on the trigger and his right hand on the gun cartridge as he turns round with his back to the camera, but in the next shot, his right hand is on the trigger and his left hand on the cartridge but in the next shot, his hands have changed position once more, this time left hand on the trigger and right hand on the cartridge.
