Trivia: When a Nazi falls from the back of the truck carrying the Ark, a "Wilhelm scream" can be heard.
Trivia: In the Well of Souls, you can see hieroglyphics of C3PO and R2D2 on the wall.
Trivia: On the plane to Nepal, the guy with the Life magazine is Visual Effects Supervisor Dennis Muren. (00:22:40)
Trivia: The filmmakers discovered to their chagrin that the snakes used for the Well of Souls sequence weren't afraid of fire at all - in fact, they would always try to get closer to the fire to warm themselves. At one point director Spielberg was caught on camera picking up a snake and telling it, face to face, "In the script, you're supposed to hate fire. Why do you like fire? You're ruining my movie."
Trivia: Pat Roach (the bald German mechanic in the fight at the plane) actually appears in the first three films. He is a former wrestler and is best known in the UK for playing "Bomber" in "Auf Wiedersehen, Pet."
Trivia: The scene where Indy shoots the sword wielding bad guy wasn't in the original script. Three months' shooting had resulted in Harrison Ford having a nasty case of dysentery, and the choreographed fight would have taken three and a half days to shoot. Harrison Ford really didn't want to stay on set that long, so suggested that it would be a good alternative if he just shot him. Who actually suggested the change isn't certain, but it wasn't a spur of the moment decision, contrary to some thoughts - it was a planned alternative.
Trivia: Another THX-1138 reference from George Lucas: When Indy gets off the Nazi Sub inside the hidden dock, you can hear over the loudspeaker, "ein, ein, drei, acht." (German for one-one-three-eight.)
Trivia: The film was originally given an "R" rating by the MPAA because of Belloq's death (his head explodes and showers everywhere). To overcome the ratings, Spielberg had flames superimposed over the image (although it thins slightly as the head detonates).
Trivia: The infamous sequence in which the three main antagonists are destroyed was achieved by: A) A hollow head model which got the air sucked out of it (Wolf) B) A head made of wax, plaster and gelatin (which melts) under a heating lamp (Toht) C) A false head being blown off by a shotgun (Belloq).
Trivia: When Belloq is yelling at Indy on the island from down in the canyon, you can see a fly crawling about his face. He doesn't flinch, nor does he make any attempt to shoo it. It eventually ends up in his mouth, and he still doesn't react. In editing they removed the few frames where the fly flew off, in order to give the impression Belloq ate it (http://www.theindyexperience.com/interviews/paul_freeman_interview.php).
Trivia: Actor Michael Sheard appeared uncredited as the UBoat captain in Raiders. He also appeared uncredited as Adolf Hitler in the Last Crusade.
Trivia: When Marion tells Indy he's not the man he was 10 years ago, Indy replies, "It's not the years, honey, it's the mileage." Harrison Ford ad-libbed this line.
Trivia: When the Nazis have taken the ark from the Bantu Wind (Captain Katanga's ship) and no one can find Indy (until he climbs aboard the sub), Spielberg actually filmed Indy diving off the ship and swimming all the way to the sub. Harrison Ford did the stunt himself, though the footage was never used.
Trivia: Throughout the entire movie, the name of Arnold Toht is never spoken once. His name is only first revealed in the end credits.
Trivia: The truck that Indy gets dragged under and the one that he blows up when he thinks he's killed Marion are actually the same truck. It was built specifically for the moving fight scene because they couldn't find a real truck that would work with all the stunts that were written for it. They used it again in the bazaar scene so that it would look like that type of truck was a common vehicle at the time.
Trivia: According to Steven Spielberg, in the scene when Indy steals the horse and chases after the truck, you can see two men in the camp are cooking a dog on a spit.
Trivia: During filming of the fight scene around the German flying wing, Harrison Ford slipped and fell down and the plane's wheels rolled over his left knee, tearing his ACL. Rather than trust in the local medical care, they simply wrapped the knee up tightly, applied ice, and kept on going.
Answer: The scene you describe was indeed filmed. It was cut out of the US release of the film although I cannot speak for the Australian version. The scene also appears in the Marvel Comics adaptation. http://www.theraider.net/films/raiders/deleted_scenes.php has a list of this and the other deleted scenes.
