Trivia: A German sentence which could be counted as a mistake: When Indy and company are taken by surprise and captured by the German troopers in the Grail temple, one of them shouts, 'Das ist ein Überfall' (it's the last sentence before the group is brought before Donovan and Elsa). This actually means, 'This is a robbery'. I can't tell, though, whether the script writers consulted the wrong material or if this is considered to be an inside joke for linguists.
Trivia: Not a mistake, but a translation. During the fighting scene on the tank. Indy is punched and hits the periscope while the solders inside watch. One of the solders says to the other "The Americans - they fight like women" in German and then gets hit by the periscope. Funny scene as it is, but better if you understand German.
Trivia: When Indy elbows Marcus off of the tank, watch the centre of your screen. A few shots later, you can see Marcus between Indy and Connery. For about one second, it looks like Marcus is laying flat on his back and a second later, he raises his legs into the air. It just doesn't look right but is extremely hilarious to watch.
Trivia: In the scene in the zeppelin where Indy talks with his father, Harrison Ford and Sean Connery both elected to shoot the scene wearing no trousers whenever possible, in close ups for example, because it was so hot and they didn't want to stop every ten seconds to wipe sweat away.

Trivia: The beach scene where Indy's father frightens the seagulls into taking flight and bringing down the Messerschmitt was done with fake seagulls and real white doves. The beach was covered with fake seagulls for the wide shot, and the closeup shots were done with white doves and piles of loose feathers to further confuse things. The film crew had to use white doves because it turned out that they absolutely could not train live seagulls to do anything at all on cue.

Trivia: Indiana Jones does not like being called Henry by his father (his proper name) and tells his father to call him Indiana. Prof. Jones replies with, "We called the dog Indiana". George Lucas created the character of Indiana Jones and he named the character after his pet Malamute dog, Indiana.
Trivia: On the zeppelin, the Nazi shows around a flyer with Dr. Jones Sr.'s picture on it. At the second table, a woman shakes her head 'no' before even looking at the picture. Possibly just the character not bothering to pay attention, as could happen in reality, but worth looking out for.

Trivia: During the motorbike chase Harrison Ford's hair is longer and Sean Connery's beard is fuller. This is because this scene was filmed after principal photography had ended, but Spielberg felt a chase scene was needed to explain their escape from the castle. The shot of Connery against a blue sky when the tank goes over the cliff was also filmed later, which again is why his beard is fuller.
Trivia: It's third time lucky for British actor Michael Sheard who pops up as Hitler. He was originally considered for the Gestapo officer Toht in Raiders of the Lost Ark but lost to Ronald Lacey. He shot some scenes as the captain of the U-boat which captures the Ark but due to rough seas causing camera stability problems, the shots were never used.He also played Hitler a few years earlier in the Uk sci-fi series The Tomorrow People.
