10 Things You Didn’t Know About Indiana Jones And The Last Crusade

10. Christopher Columbus Wrote A Draft

As well as being named after the man who nicked the land of Native Americans, Chris Columbus will be known as the man who made some of the most beloved family films in history (and also Christmas with the Kranks). The Home Alone and Mrs. Doubtfire director was ready to collaborate with Spielberg for the third Indiana Jones feature, with Columbus writing a script entitled "Indiana Jones and the Monkey King".

The film took Lucas' original idea of a haunted house as the prelude to the main adventure, which saw Indy travel to Africa in search of the resting place of Sun Wukong. It featured a tank chase on a rhino, a centuries-old pygmy, river pirates and Indiana having a relationship with one of his students.

Written in 1985, the complete script was leaked onto the internet years later, with many fans believing it to be a draft for Indiana Jones 4. Find it and read it, it's honestly pretty good. The truth was revealed though that it was for the third film and was eventually rejected in favour of the Holy Grail story.
