Factual error: When Indy wakes up on the day of New York City's parade for the Apollo 11 astronauts, H.R. Pufnstuf is on the television. The parade was held August 13, 1969, but H.R. Pufnstuf didn't premiere until September 6, 1969.

Revealing mistake: When Indy is in the archive room cornered by the thugs, there are a couple of wide shots where it's definitely not Harrison Ford, but a stuntman with a mask resembling his face. The wide shots cut to close-ups of the real Harrison, and one can see the big difference between both. According to the making-of videos, several stunts were played using this technique.

Continuity mistake: When Helena and Indy are cornered in the archive room, Helena—in the background—rushes upstairs. A shot later, she is metres behind, arriving at the steps again and repeating all previous movements.
Continuity mistake: When the soldiers bring Indy to Weber, in the background Voller and the two soldiers with the lance can be spotted already leaving. After Weber finishes interrogating Indy, Voller and the soldiers are back in their original places with the lance.
Character mistake: In the plane, Mason says that Voller's associates killed three American civilians. But they only killed two: Mandy and Plimpton.
Continuity mistake: During the conversation in the Tuk-Tuk, Helena's right arm continuously goes from being down to grabbing the roof of the Tuk-Tuk between shots.

Continuity mistake: Weber commands a soldier to open the Lance's box. In the shot of the soldier's hands, a ring has appeared on his left hand. This ring disappears again when Weber says "Doctor."
Continuity mistake: When Indy horseback rides on the subway platform, the people stand behind the columns. A shot later from the opposite angle, they're all standing in the middle of the platform.

Continuity mistake: In the college archive, Indy opens the cardboard box. In the close-up he opens it again.

Continuity mistake: When the waiter arrives at the room where the Nazis are, all the papers and books on the table, plus the pencils, change positions between shots.
Continuity mistake: When Renaldo gives instructions on diving, he holds several cables. From the shot from behind, he is grabbing them close to a tape that holds them together. Shot changes and the grip differs, and the tape is gone.
Revealing mistake: During the parade, after the red convertible skids, Indy's horse rears. When it turns around, check Indy's face and you'll notice that it's Harrison Ford's stunt.

Continuity mistake: Indy tries to make a phone call but is abducted by the baddies. There's a close-up of the phone and blood has suddenly appeared all over it.
Continuity mistake: When Helena is doing the magic tricks, Renaldo reaches for the cards with both hands. Shot changes, and he is reaching just with one.
Continuity mistake: Before the tuk tuk comes to a stop, a man in a blue djellabah is walking by next to it. When the tuk tuk stops, the man is suddenly 3 meters behind, repeating all previous movements.

Factual error: The crown on the logo of the Air Maroc plane is the modern 2013 version, not the one from 1969 when the movie is set.

Continuity mistake: Indy stops Basil from hammering the dial and makes the left side of his jacket open to reveal his shirt. Shot changes, and now the opening has swapped sides.

Continuity mistake: Indy horseback rides past a truck with a flag, then between a dozen of musicians while chased by a motorbike. When he looks behind him, the band has vanished and the truck is next to him again. This last shot belonged in the first place.
Continuity mistake: Before Indy jumps on the horse during the parade, a man in a plaid shirt runs away. Shot changes, and he is back in the previous position, yet he is now walking slightly faster.






Answer: He was an American Neo-Nazi.

But his surname sounds German. It might suggest that he is an American Neo-Nazi of German descent.
Yes, of German origin. "American" is not a race or ethnicity, is made up of many cultures, and is only a nationality. Klaber is an American citizen likely with German ancestry. American Neo-Nazis are of many different racial backgrounds. They adopt Nazi ideologies.

German is also a nationality, not a race. To be clear.

German is a nationality, referring to citizens of the country of Germany, and also an ethnicity, traditionally characterized by certain genetic traits, certain facial features, light-coloured eyes, blond hair, etc. "American" is only a designation of citizenship, not any particular racial or ethnic makeup.

That's not true. People with those genetic traits (like me) are not "German" or "Germanic." Maybe Aryan or Caucasian. Those are ethnicities. Not German. Germans are only distinguished by their use of the Germanic language, not their appearance. Also, certain Germanic tribes were very far from blond and light-colored eyes.
