National Geographic digs into the history behind Indiana Jones and the Dial of Destiny | Nat Geo

HELENA SHAW: Dad told me you found something. A dial that could change the course of history.

HARRISON FORD: With Indiana Jones, I always thought that what would be interesting, is to see this educator adventurer fooling with the nature of science.

JAMES MANGOLD: In our movie, the relic is rumored to be an invention by Archimedes. The research that I found about the Antikythera really fueled me. In the cave set, all the things that Archimedes invented, the lever, water displacement, all the mathematical figures are all a part of the design.

HARRISON FORD: The story is an intriguing intellectual puzzle.

JÜRGEN VOLLER: Doctor Jones. Get him.

HARRISON FORD: As well as a physically arduous film.

RENALDO: Indy!

HELENA SHAW: Indy!

BASIL SHAW: Indy!

HARRISON FORD: I always prefer to work on a physical set to a virtual set. Physical sets bring physical reality.

KATHLEEN KENNEDY: Harrison wants things to be real.

JAMES MANGOLD: We spent weeks in Morocco with these revved up tuk tuks smashing down the streets of Tangier.

TEDDY: Turn left! Turn left!

JAMES MANGOLD: Then Sicily...

INDIANA JONES: Hang on!

HELENA SHAW: Indy!

JAMES MANGOLD: Sicily came to play because it's where Archimedes lived basically his whole life.

JÜRGEN VOLLER: Fasten your seat belts.

HARRISON FORD: You'll always face the challenge of bringing something new and something different.

PHOEBE WALLER-BRIDGE: There's excitement and danger and not knowing what's going to happen next and the twists and turns... it always felt like a real romp.

INDIANA JONES: Get back!

INDIANA JONES: You stole it.

JÜRGEN VOLLER: Then you stole it.

HELENA SHAW: And then I stole it.

SALLAH: Give em' hell, Indiana Jones!

HARRISON FORD: I'm delighted for the audience to see this new adventure.
