Corrected entry: In the scene in the army warehouse, Indy asks for gunpowder from the Russians because he says the metal in it will help track down the magnetized crate. Gunpowder has nitrate, coal, and sulfur in it, but no metal.
Corrected entry: In the scene in the army warehouse where everything metal was being attracted to the magnetic crate, the Russians' guns should have been pulled away, or at least toward the crate, as well.
Corrected entry: In the hangar at area 51, Jones says something like "drop your guns or Spalko is dead". Later when being interrogated by the FBI/CIA guys, he doesn't know who she is, he only gives a physical description of her.
Corrected entry: After Indiana Jones was fired from the University, he said he would go to Leipzig to teach. In 1957, Leipzig was behind the Iron Curtain and deep within the Soviet Communist Zone of East Germany. This makes no sense since, prior to Indiana Jones saying he was going to Leipzig, the Soviets had kidnapped him and almost killed him before he escaped. Doubtful they would later welcome him with friendly arms or that he would ever entertain the thought of even stepping foot in Leipzig.
Corrected entry: The female Russian spy's uniform looks more like the German WWII era uniforms than USSR ones of the time. Additionally, her holster is on the front on her right hip. Soviet officers wore their holsters behind their right hips.
Corrected entry: Mutt always has a knife with him that he uses to get out of tricky situations. This reflects Indiana's use of his whip. Another hint of their actual relationship.
Corrected entry: After being captured, Indy is shackled to a chair, unable to move his arms. Later, "Ox" staggers into the tent, and we see from behind as Indy reaches up and grabs his arm to steady him. Later still, Indy is again shackled to the chair.
Corrected entry: To keep the plot a secret, this film has had quite a few fake titles, including, but not limited to: Indiana Jones and the Destroyer of Worlds, Indiana Jones and the City of the Gods, Indiana Jones and the Four Corners of the Earth, Indiana Jones and the Lost City of Gold, and Indiana Jones and the Quest for the Covenant.
Corrected entry: This film had been in the works for a long time, mostly because of problems with the script and inability to settle on a McGuffin, or plot device. Several screenwriters had been commissioned to write scripts, but none were satisfactory, and in one case, the screenwriter couldn't get Lucas and Spielberg to concentrate. Writers also didn't want to approach the task, because they felt the shoes Lucas and Spielberg wanted them to fill were too big. Eventually, however, Lucas and Spielberg settled on the crystal skull as the McGuffin and also upon a screenplay which they thought was what they wanted.
