Which Indy quotes at one point if I remember correctly...
I think I read that George insisted that the basic concept of Indiana Jones was of an everyman type character, right down to the name 'Jones' who becomes embroiled in far-out and fantastical type adventures, but was never quite up to the task...
What I absolutely love about Indiana Jones is that he almost always has the 'prize' just within reach, but then loses it, but gains something else...
In Raiders, he fails to get the Idol, but manages to get away with his hide intact, he gets the Ark and then loses it again, but gains Marion (and then loses her again, we now know)
In Temple of Doom, he fails to get the Diamond, but gets the antidote, he misses out on the Sankara Stones, and fortune and glory, but saves the village...
In Last Crusade, he fails to get the Grail, but heals his relationship with his estranged father...
In Kingdom, he solves the history behind a culture, but the proof is lost forever, although he wins Marion (again)
