Corrected entry: When Indiana finally breaks through the giant 'X' on the library floor, he simply pops out the remaining marble in that area. In reality, the marble "tiles" would have been held together by some sort of cement joint, rendering it impossible for him to remove a neat square of marble without using some sort of cutting tool first.

Corrected entry: In the library scene, the Grail Protectors hit Marcus in the head and drag him. What kind of spies/soldiers/agents are they if they didn't find the grail diary on Marcus's pocket? Surely the book would be interesting to them, since it contains lots of directions to find the grail...
Corrected entry: In the scene in the castle, the weather outside is changing dramatically. When Indy enters his father's room, it is very dark and pouring rain. When in Elsa's room, the sunrise is shining brightly through the windows. When in the large hall, we can hear thunder again and see reflections of water running down the windows.Jacob La Cour
Corrected entry: There is a problem with the following scene: The Nazi plane crashes into the tunnel, slides past Harrison Ford and Sean Connery and explodes when exiting the tunnel. The problem is that the plane shouldn't explode since its wings (filled with gas) were torn off. It couldn't have been a bomb attached to the plane either, since, as it is seen only seconds afterwards, a bomb would leave a big crater in the street and make it impossible for the car to go on. Yet, Harrison Ford has no problems at all driving through what's left of the plane.
Corrected entry: In the library scene Indy spots the Roman numeral X on the floor. The X is a dark green and the marble around it is a light green colour. When Indy eventually smashes through it the camera pans back to show that the X has gone and that all the marble is dark green. (00:27:50 - 00:28:45)
Corrected entry: In the scene where Indy and Dr. Shneider are looking for the Roman numerals in the library, look closely at the signs specifying where to go to find a specific category. You may need to use the Zoom button, but they are printed in English. They are in Venice: the signs should be in Italian.
Corrected entry: That camouflage bridge at the end is in fact just a rock bridge painted to blend in with the other side of the canyon. Fair enough. That doesn't alter the fact that when Indy looks down into the void there is nothing there, just blackness. Camouflage or not, the bridge should be visible when looking straight down.
Corrected entry: When the tank driver has been shot, he leans on one of the levers. The tank slews round, saving Indy. In the next shot it shows the tank heading straight forward. This would not happen if the driver is still leaning on the lever. Even if one of the crew takes over, they would see the canyon up ahead and steer away from it.
