Plot hole: Hiding in a fridge (or anything else) in order to be conveniently blown out of the way by an exploding nuclear device is absurd beyond belief. The fridge is just so much extra reaction mass and would be vaporised by the expanding nuclear explosion - it wouldn't be daintily picked up and thrown a few kilometers to safety. If it was, why doesn't it land in a shower of similar artifacts which have also been dislodged and thrown around? Incidentally, even if it was thrown out of the way as shown, anyone inside it would be turned into a smear of strawberry jam by the acceleration required to beat the shock and heat wave of a nuclear blast, and then liquefied by the deceleration involved in hitting the ground at that speed.
Continuity mistake: At the beginning when Indy is talking to Spalko, his hands keep alternating from being in his pockets to just resting at his sides between shots.
Marion Ravenwood: I'm sure I wasn't the only one to go on with my life. There must have been plenty of women for you over the years.
Indiana Jones: There were a few. But they all had the same problem.
Marion Ravenwood: Yeah, what's that?
Indiana Jones: They weren't you, honey.
Trivia: In the Mayan temple, Indy comments "I have a bad feeling about this." This line was a running gag in George Lucas' Star Wars saga, and was used by Harrison Ford at least once. (01:46:10)
Question: Perhaps I've forgotten some details from The Last Crusade in the years since I've seen it, but shouldn't Henry Sr. not be dead in this movie, because he drank from the Holy Grail which gives immortality?
Answer: Yep, you've forgotten some details. The Knight specifically states that the immortality bestowed by the Grail is limited to those who remain within the shrine. Jones Snr left the cave, ergo, no immortality.
