Producer
Frank Marshall has confirmed that the film is set in
1957, making it nineteen years since
Indiana Jones and the Last Crusade, thus acknowledging the real-life passing of years between films. Indiana Jones is having a quiet life teaching before being thrust back into his old adventuring. He battles agents of the
Soviet Union for the
crystal skull. "The theory is they are shaped by higher powers or alien powers or came from another world, or an ancient
Mayan civilization had the powers," Marshall explained. Indy's journey takes him across
New Mexico,
Connecticut,
Mexico City, and the jungles of
Peru, as well as the warehouse from the end of
Raiders of the Lost Ark, where numerous treasures including the
Ark of the Covenant are kept safe by the US government.
