Trivia: Tom Selleck was chosen for the main role but he was already involved in Magnum P.I. The show had a chapter named Raiders of the Lost Art as a nod to this, showing him playing Indiana Jones.
Trivia: The main role of Indiana was offered to Peter Coyote, Tim Matheson, John Shea and Tom Selleck.
Trivia: Because of his commitment to the film, Harrison Ford was unable to play Han Solo in the NPR radio dramatization of Star Wars. The role was taken over by Perry King, who had been among those auditioning for the role in the movie before Ford was cast.
Trivia: Arnold Toht has only 16 lines in the entire film.
Trivia: Originally, the golden idol had moveable eyes that were supposed to follow Indy's moves when he is about to snatch it. Compare the idol inside the temple to the one Belloq later holds in his hands.
Trivia: At the end of the movie, when they lift the top off the Ark, this was actually the sound of a toilet top being pulled off.
Answer: Indy and Marcus Brody believed that the Ark needed to be studied. They certainly didn't want to put it back where it was found. They believed that the U.S. government would find the best archaeologists, researchers, and scientists in the world to study the Ark. They are both upset that instead, the government has decided to simply lock the Ark away. This is why Indy says, "Fools. They don't know what they've got there," as he is leaving the building.
