Trivia: When Belloq and his men reach the town of Cairo after being swiped by Indy and the van with the Ark inside, notice Ronald Lacey's character Toht. In this entire scene you don't see his face, totally shadowed by his hat - his head doesn't even move! Was Ronald unavailable for filming and hired a double...?
Trivia: The rolling boulder in the opening scene was actually 22 feet in diameter and was made out of fiberglass. (00:09:20)
Trivia: Indiana Jones could have escaped the rolling ball of rock by simply standing still, because the boulder started out about 15 feet over his head. Even if the boulder ended up blocking the entrance, there are several shafts of sunlight visible throughout the tunnel, indicating several potential points of escape.Charles Austin Miller
Trivia: When Indy swims to catch the U-Boat, the DVD and video cut out the part which ran in Canadian theatres (if not wider) where he lashes the whip to the periscope. This is probably due to the fact that just previously, Indy used the whip while he was dragged at the back of the Nazi truck and never picked it up. It was loosely hanging and about to fall away from the truck. I am assuming this was pointed out to the producers and they cut out blatant evidence of the whip being used.
Trivia: When "Raiders of the Lost Ark" premiered in France in 1981, audiences there honestly believed that it was an adaptation of the 1964 French adventure film "L'Homme de Rio" (That Man from Rio), directed by Philippe de Broca and starring Jean-Paul Belmondo. The French film is about a soldier on-leave who gets mixed up in a museum heist and kidnapping and goes on a wild intercontinental chase to track down three museum pieces. The action is similar in both films, as are some of the plot twists (such as both heroes being rescued from certain death by a crowd of children, for example). Although French audiences immediately recognized the similarities between the two films, Steven Spielberg denied ever seeing "L'Homme de Rio".
Trivia: Producer Frank Marshall is also listed in the end credits as "Pilot" - Steven Spielberg often uses his film crew and producers as extras.
Trivia: Actor Peter Coyote auditioned in costume for the part of Indiana Jones, but he tripped and stumbled over power cables during the audition (conveying an awkward and nervous image, just the opposite of the confident and sure-footed Indiana Jones image that Steven Spielberg wanted). So, Coyote didn't get the part. But Spielberg never forgot Coyote's earnestness, and he later cast Coyote as the compassionate Agent Keys in "E.T. The Extraterrestrial".Charles Miller
Trivia: Although it lasts for six minutes on screen, the truck chase sequence took five weeks to film.
