There’s a running joke in Indiana Jones and the Last Crusade that Indy took his nickname from the family dog. That joke has some truth to it though because as George Lucas was developing Raiders of the Lost Ark, he actually named the character after his dog, Jones (the “Indiana” was a riff on Steve McQueen character Nevada Smith). Coincidentally, the same dog was the inspiration for Chewbacca in Star Wars. Need more Raiders of the Lost Ark facts?
