300 Million Dollars Worldwide in 5 days will be enough for these guys to comeback and do another one I suppose. Lucas ( I love Lucas, but damn him, I think he's losing his mind) is talking about making an Indy 5 with Shia not at the helm, but as the focus, and Ford taking on more of a Connery like role. However, Spielberg and Ford shot down the Saucer Men from Mars that Lucas was wanting to make, so I'm guess they still have veto power on Lucas.
Anywho, I loved the movie. The Crystal Skulls have always fascinated me, plus I lived in Peru and in the Amazon for a while, so I was pretty familiar with the Nazca and Incan mythology in this film. My Archaeology degree actually means something.
Plus anyone calling bullshit on the backstory of the "aliens" and all that, I'll show you some pictures from my own album of the morphed mummies that I saw. Good shit I tell you.
