Plot hole: When Indy and Sallah visit the gentleman who translates the staff headpiece for them we hear the staff should be "six cadams high." Indy replies, "About 72 inches." Then, turning the headpiece over, "Wait - take back one cadam to honor the Hebrew God whose ark this is." It's definitely referring to the staff length - Indy says afterwards "Their staff is too long." So, about five feet now, right? But, when Indy goes to the map room the staff is much taller than him. If the staff is about five feet high, Indy would be around three feet tall. (00:48:25 - 00:53:05)
Plot hole: Bond makes a huge tactical error after diving to the St. Georges. He knows the Russians and their operatives are after the ATAC. The ATAC itself is expendable to Britain, since it has a self-destruct mechanism that under proper procedure would have been set off when the ship sank. So why is Bond trying to retrieve it? Because he disarms the self-destruct, he actually allows Kristatos to get his hands on it, forcing Bond to track it down again and, to stop the Russians from getting it, HE DESTROYS IT! So why doesn't Bond, instead of disarming the self destruct, set a timed charge or toss a grenade in the room to destroy the ATAC while its at the bottom of the sea? The answer is, of course, that if Bond destroys the ATAC before the bad guys can get at it, the movie's over. Even so, at the end, when Bond finally does destroy the ATAC, he tells Gogol it's "detente. You don't have it. I don't have it." Clever line, but it reinforces the fact that the British don't need it. They can build another one.Vader47000
Plot hole: When Snake, Brain, Maggie, and the President get to the car at the WTC, Snake opens the hood when the car is dead, and somehow he is out in the open when the Duke is about to shoot. First, how would he get there with a crossbow trained on him, and second, how did Maggie pass the revolver to him, when he hands it to her to open the hood of the car? (01:21:05 - 01:21:50)
Plot hole: Max drives from the hillside to the crashed car to save the occupants but the guy with the crossbow doing up his boots somehow doesn't hear Max's V8 engine approaching, or hear Max get out and sneak up on him, this area would be quiet and Max must have parked nearby to get the injured man to his car.
