25 Things You Probably Didn't Know About Indiana Jones

21. Back To The Future Inspired The Fridge Sequence - Crystal Skull

The original plan in Back To The Future was for the time machine - so iconically modelled on a DeLorean - to be a fridge, but ultimately the idea was rejected by producer Steven Spielberg who thought impressionable children would lock themselves in their fridges. Probably a legitimate concern. The same idea - minus the time travelling - was resurrected for The Kingdom Of The Crystal Skulls in which Indy of course survives an atomic bomb blast (the powerful trigger for time travel in the original BTTF script) by hiding in a fridge.

20. A Dentist Inspired Raiders Of The Lost Ark

In 1973, before George Lucas had even made Star Wars, he wrote the original idea that would become Indiana Jones with the intention of making a modern version of 1930s and '40s film serials. Ultimately, he shelved the idea, but not before discussing it with director Philip Kaufman, who helped on the idea conception, and introduced the idea of the Ark of the Covenant having been told about it as a child by his dentist.

19. ...And So Did Uncle Scrooge And James Bond

George Lucas managed to convince Steven Spielberg to work with him on Raiders Of The Lost Ark despite the director's expressed his desire to make a James Bond movie. Lucas told him his character was better than Bond, and sold him on the idea of what Spielbegr would call "a James Bond film without the hardware." The origin was called back to with the casting of Sean Connery, which was chosen as an inside joke. A year later, during the intensive storying process, Spielberg conceived the idea of Jones being chased by a boulder, which was inspired by Carl Barks' Uncle Scrooge comic "The Seven Cities of Cibola" and which would not be the only idea taken from the comics, as George Lucas later admitted.
