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.
Continuity mistake: As Sallah pulls Dr. Jones senior off the tread of the tank, Indy lets go of his whip and turns towards the German colonel and they continue fighting face-to-face. You can see that Indy punches the colonel so that he loses his balance and stumbles backwards. A split second later, the colonel is standing behind Jones with his arm around Indy's neck. They did not have nearly enough time to so radically change positions. (01:32:15)
Continuity mistake: The lion approaches Indy from the rear of the circus car and walks towards the center. Next shot, the lion approaches from the back of the car again.
Continuity mistake: The Joneses take off in the Zeppeliner from Berlin. Shortly after takeoff they are over tall snowy mountains but there are no tall snowy mountains that close to Berlin.
Continuity mistake: When Indiana pushes the Nazi colonel out of an open window, if you look carefully, the colonel fell a few metres out of the zeppelin before landing on a pile of suitcases, but when the colonel looks up, the zeppelin is several hundred metres above him, in too short a time to ascend that much.
Continuity mistake: When Indy enters the beach he steps on dry sand and then on the wet part. A frame later, in a wide angle, he is still stepping on dry sand.
Continuity mistake: When Indiana is fighting on top of the tank, he kicks the periscope. It spins counter-clockwise, but the handles inside spin clockwise. (01:32:45)
Continuity mistake: Indy pours water from the grail into his father's mouth. Between two consecutive shots, the position of Indy's hand changes and the direction he pours changes 90 degrees.
Continuity mistake: The shape of the exploded canon barrel on the tank changes a lot in the different shots. Especially between the scene right after the explosion and the scene where Indy is hanging under the barrel.
Continuity mistake: When Indy meets Hitler, there is a shot over Indy's shoulder that shows his lips are slightly parted (relaxed). Cut to Indy's face and he closes his mouth tightly. In the very next shot, with no elapsed time, we see from Indy's shoulder again that Indy's mouth is relaxed as before. (01:10:15)
Continuity mistake: The Zippo lighter on the floor, thrown by Dr. Jones, keeps moving around between shots.
Continuity mistake: In Berlin, Indy grabs his father's book from Elsa's trenchcoat. In the next shot, the Nazi pin on Elsa's tie has disappeared.
Continuity mistake: When Indy shoots the three soldiers on the tank they fall sideways but not off the tank, a few seconds later all three bodies have disappeared.
Continuity mistake: When Sallah pulls his rifle and overtakes the Nazis at the Great Seal he is in the forefront with the Nazis in front of him and Indy and his father are behind him. Within the next scene he is now in the background with his rifle resting in his arms.
Continuity mistake: When Indy is pouring the water from the Grail onto his father's wound, we see him pour all the water out. When his father takes the Grail, there's now water left inside.
Continuity mistake: Onboard the ship at the end of the prologue, after Indy grabs the cross before it falls over the side, the guy in the white suit climbing up the steps. He's only reaching the top as the shot changes. In the next shot, he's already a few steps away from the top of the steps, telling his men to stop Indy.
Continuity mistake: During the temple quake sequence towards the end of the film, Elsa fails to maintain her grip on the rising earth and falls onto tilted ground, sliding towards the chasm. At this point, Sallah is kneeling on the ground, but in the very next shot, he is now grabbing hold of Henry.
Suggested correction: Automatic refilling seems to be the least of the miracles the Grail has performed.

There was no evidence of this, plus we never see it refill before or after. How would it be empty when they first find it if it miraculously refilled itself? This is a poor correction just to make a correction.
