Indiana Jones and the Last Crusade

1) I would like to speculate a little as to the title of the film. It's fascinating that the movie would steer away from the original grail legend and move on to the tales of the crusades, however it does make sense because the grail legend was mixed into the crusades. This makes sense to me because if there was a grail search today it would more than likely involve the latest grail search, which would have been the search's done during the crusades. All-in-all I believe the title of the film as "The Last Crusade" may be more due to the fact the writers used mostly crusades lore when writing the movie although I find it fascinating that a few of the ideas of Perceval made it into the movie.

2) The ideas that made it out of Perceval are many in number although there are a few major ones that I would like to point out. One is the entire idea of the grail being "unattainable", while the Jones do find the grail and drink from it they lose it in the end. It heralds the Perceval legend by never allowing the world to truly grasp the grail. The other interesting parallel is the use of numbers in order to present clues, for instance Jones Jr. found the second knights tomb in the library by using the numbers on the wall.
