Continuity mistake: While in the Germans tank, the right side of Marcus's jacket is bent and wrinkled. A Frame later it looks perfect.
Continuity mistake: Indy and co. leave their horses a way from the steps to the temple, but when we cut to a closer shot they're very close to the entrance.
Continuity mistake: In the Grail temple, when Salah says "Drop your guns please," he is holding a rifle. When Indy instructs his father a few seconds later to get up, Salah is not holding a rifle but has his hands crossed.
Continuity mistake: In the scene in the temple after the two soldiers attempt to get past the first task, the first soldier is seen on his back holding his head beside him. When Indy attempts the first task, both dead soldiers are on their stomachs with no heads in sight.
Visible crew/equipment: When Indiana and the Protector of the Grail are fighting in the boat that is about to be chewed up by the giant screw/propeller, when the angle changes to the top point of view, you can see the rope pulling the front of the boat around to position the rear for destruction... (00:39:10)
Continuity mistake: At the airport, someone is reading a newspaper. Instead of the year 1938, the date of the newspaper is 1918 (a guess: I think this mistake happened because the art director wrote the date in a rush, stretching the "3" in a way it seemed a "1" when the people of "atrezzo" saw it).
Continuity mistake: While Indy and his father are talking in the zeppelin, the amount of flowers in the vase keeps changing between shots.
Continuity mistake: When the tank is about to go over the cliff you can see that there is no one sticking out of it, but in the next shot, Vogel can be seen sticking out and yelling.
Suggested correction: This entry is incorrect. Vogel is always visible as the tank is going over the cliff.
Continuity mistake: While the German tank travels to the temple, it passes a German soldier. Inmediately after, a very wide angle shows the soldier has dissapeared.
Continuity mistake: Jones Sr. falls on the tank's chain and passes by the turret and by a round rusty thing. When the angle changes, a second before Indy saves him with the whip, you see Sr. has moved half a meter back instead of forward, and is passing by the same elements as before.
Continuity mistake: When the Zeppeliner turns back towards Berlin, it is over snow covered mountains. But when the Joneses escape in the biplane there is no sign of snow anywhere.
Factual error: When Hitler signs the diary, he writes in a modern way of writing. But in the late 30s there was a different style of writing called "Suetterlin". The letters looked quite different from nowadays. (01:10:25)
Continuity mistake: Indy throws the German officer out of the zeppelin window and Senior stands up to watch it all better. Then he sits down. Angle changes to a wider view and Senior is back on his feet, head almost out of the window, repeating the previous movements.
Continuity mistake: Indy and a soldier fall down on the tank, right where some bags are. From the next angle they are half a meter before the place where the bags are.
Revealing mistake: Just as Elsa leaps from one side of the precipice to the other as the Temple collapses, a rock rolls from right to left and hits her right in the head before bouncing off. (01:56:35)
Revealing mistake: A bomb falls in front of Indy's car, creating a crater where the car falls into. Dr. Jones Sr. doesn't move forward due to the momentum of the crash, revealing he's been replaced by a dummy.
Continuity mistake: When Indy is looking up at the front of the Grail temple it is bathed in direct sunlight. Indy dismounts his horse in the shadow. However, in the shot just before dismounting, the cliffs behind Indy are also bathed in direct sunlight. That is impossible.
Continuity mistake: When Young Indy is hoisted from the lion's carriage on the train, one of the baddies is holding a gun at him, in the next shot, the gun is down by his waist.
Continuity mistake: When Indy gives his father water from the grail to drink, the grail glows from inside, and the gold inside it is bright and even. But when Indy pours water over the wound, the grail is dark inside and there are dark patches in the gold. Obviously, they had to take the light that made the grail glow out so it wouldn't be seen when Indy pours the water over his father.
Continuity mistake: The 109s that are animated are shaped like the original German fuel injected ones. The shots where it's a real plane show the modified one with a RR Merlin engine that gives it a weird square nose.
