Interesting glimpse into the creative process.
The hero, Lucas explains, is a globe-trotting archaeologist, “a bounty hunter of antiquities.” He’s a professor, a Ph.D.—“People call him doctor.” But he’s a little “rough and tumble.”
As the men hash out the Jones iconography, they refer, incessantly, to other films, invoking Eastwood, Bond, and Mifune. He will dress like Bogart in “The Treasure of the Sierra Madre,” Lucas says: “the khaki pants…the leather jacket. That sort of felt hat.” Oh, and also? “A bullwhip.” He’ll carry it “rolled up,” Lucas continues. “Like a snake that’s coiled up behind him.”
“I like that,” Spielberg says. “The doctor with the bullwhip.” –Spitballing Indy: George Lucas, Steven Spielberg, and the creation of Indiana Jones : The New Yorker.
