Harrison Ford as Indiana Jones, “Raiders of the Lost Ark”
Original Casting Choice: Tom Selleck was committed to film “Magnum P.I.” for the small screen and forced to trade a brown felt fedora for a loud Hawaiian shirt.
Why the Switch Worked: Mixing clenched-jawed heroism, dry wit, and vulnerability—the fear of snakes! The professorial bumbling!—Ford created a singular screen hero. And three (soon to be four) movies later, who can imagine Indy with a ‘stache?
