Harrison is just jonesin for another big paycheck, and in denial with how horrible the film really was. When he is the one who in the 90's dragged his feet over the alien story because as he rightly said aliens don't belong in indiana jones.
More Screen time for Shia Lebouf, no thanks i think i'll pass. Unless someone give me a ticket to a free screening so i can look for the bad new scenes that top nuking the fridge.
Crystal Skull was good for one thing though without it we never would have gotten the term nuked the fridge. It brought a great new term for fans to replace jumping the shark aka fonzi's dumb stunt on happy days. I have forgiven the producer of the show though because he never created anything like Jar Jar Binks, not even Mork From ork.
George and Steven thought they were being reel clever inserting a duck and cover like joke into the film. They made the film into a self parody of the other 3 films. It had more in common with a brendan frasier mummy movie, x-files or national treasure than it did indiana jones.
No religious artifacts, no occult, no archeology because that has nothing to do with aliens but the study of human cultures and history. The old bad idea that aliens built the pyramids was torn to pieces by science a long time ago. Basing a movie on the very bad novel chariots of the gods has to be the stupidest idea next to george getting his ideas from l ron hubbard and scientology.
George for years has been removing any sense of spirituality from his films as well as trying to get rid of the guns. That is why greedo shot first to make a point against the republicans and the nra. Poltical correctness. Also why he added midi chlorians to episode 1 instead of keeping the force quasi religious. That is why he went with aliens instead of another artifact like exacalibur, or the lance of longinus.
