Continuity mistake: When young Indy discovers the thieves in the caves, the pot on the right swaps from laying horizontal on the ground to slanted and back to horizontal, depending on the angle.
Continuity mistake: Young Indy grabs the Coronado cross, but from the next angle his hand is away about to grab it, and also its position has changed.
Continuity mistake: When Indy escapes out of his office through the window, there are no shadows around. Half a second later, from a different angle, two long shadows have appeared underneath the window.
Continuity mistake: At the very end of the movie, when they all ride off through a tunnel, you can see all sorts of tassels hanging off each of the horses. When they reach the end of the tunnel and are riding off into the sun, there are no tassels at all apparent.
Revealing mistake: In the shot of Elsa falling to her death into the misty chasm in the Temple, you can see that it is not Alison Doody but a stunt double.
Factual error: When Indy and his father rotate into the control room, the eagle on the uniform of the woman who raises the alarm is on the wrong side, left instead of right.
Suggested correction: As it's an SS uniform, the eagle insignia should be on the upper left arm.
Continuity mistake: The blood on Indy's left ear disappears at the end of the film.
Continuity mistake: When Indy kisses Elsa in her room in Venice, you can see there is nothing on Elsa's left shoulder, but when the camera angle changes in the next shot, Indy now has his hand on her shoulder.
Visible crew/equipment: In the catacombs after Indy passes the picture of the Ark Of The Covenant and approaches the next wall with the lighter, (when the screen goes upwards a bit) the shadow of a boom mic can be seen dropping into view at the top of the lighted wall. (00:31:40)
Continuity mistake: Indy slams a pole against the big X on the floor and produces a hole. When the angle changes the shape of the hole is completely different.
Revealing mistake: When the tank shoots-up the jeep the interior is revealed to be empty and such a prop.
Continuity mistake: While in the zeppelin, the German officer extends his baton and lowers Dr. Jones's newspaper, wrinkling it. From the opposite angle, the newspaper is still raised and the officer repeats the previous movements, though this time he doesn't wrinkle the newspaper.
Continuity mistake: Hitler walks surrounded by a huge crowd ahead holding Nazi pennants. When Indy bumps into Hitler, half a second later, the pennants on the left have disappeared.
Continuity mistake: Dr. Jones hugs his son and walks 20 meters away. When he turns around to address him, he is barely 5 meters away.
Continuity mistake: When a jeep gets stuck to the tank's cannon, the type of jeep, its position and the damage done changes between the first and second shot (watch how the smashed windows fix themselves, for example).
Continuity mistake: In front of the main tribune there's a pile of burning books. First the fire is just atop, a frame later the whole pile is burning.
Continuity mistake: When Indy jumps on Kazim's boat, Elsa's boat is inches away from Kazim's, but a shot later she has managed to appear somewhere else with no boats around.
Continuity mistake: When about to walk on air in the temple, Indy says, "No one could jump this". In the close-ups his hands are spread apart, but in the wide angle they are grabbing the diary.
Revealing mistake: Dr. Jones fires at the jeep from the tank, but the explosion doesn't come out the cannon, nor by the jeep's window next to it; instead the back of the jeep explodes.
