Continuity: 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.

Factual error: When Indy and his Dad are in Berlin, there is a big book burning going on. But the only book burning that was held in Berlin was May 10th in 1933 - 5 years before the Joneses visit it in search for the Holy Grail.

Continuity: In the beginning where Indy is young, he fights some guys on that zoo train. When he's on the crate with the rhino in it, the background changes in each shot. Once there are trees behind and a split of a second later there are rocks, once there's a cliff and once a plain, and it all changes in splits of seconds as they change shots.

Continuity: When Indiana is drinking champagne with the businessman in the fancy apartment he holds his glass by the stem in one shot and then by the bowl in the next shot. As the conversation continues the glass goes up and down in Indiana's hand like a yo-yo.

Factual error: When driving from Venice to the castle we see a map of the route. In it Austria is marked with its own borders and its name is indicated. But in 1938 (which is after the anschluss), Austria no longer existed. It was part of Germany.

Other: In the scene with the tanks, Indy rides up beside one with a rock. Watch the gun closely. The end of the one that he is supposed to shove the rock into is wobbling inconsistantly with the rest of the gun, or the tank for that matter.

Continuity: When they are first looking over the cliff at the tank, Sean Connery's beard is quite full, and in a shot moments later, still looking off the cliff, it has been trimmed.

Continuity: When Indy is rescuing his father from Brunwald castle, he uses his bullwhip to smash through the window of the room his father is kept in...but in the time it took to jump into the room and get smashed over the head by his father, the bullwhip he used would have lost lots of its momentum and it wouldn't be waiting for him to grab it and use it later on the movie.

Factual error: In the scene where Hitler signs the diary, he writes in a modern way of writing. But in the late 30's there was a different style of writing called "Suetterlin". The letters looked quite different from nowadays.

Continuity: The back of the boat gets chewed up by the prop, in the same place twice.

Revealing: When the VW gets stuck on the front of the tank and is shot off, you can see that the car has no engine, no body in the car, and no clutch. Also, when the car is blown away you can see a wire used for the stunt fall right in front of the camera.

Continuity: During the big chase scene leading up to the three challenges, Indy uses his gun and begins to takes the high road on his horse.  Harrison Ford couldn't seem to find the holster for his gun, so you can see his holding the gun by his side until the scene changes.
