Hi, yes, I love the Indiana Jones movies too
and have DVD of 3 past parts.
here we can easily find it but not good quality(is curtain recorded quality) as I have a bad habit to see high quality then have to wait for original quality DVD.
about Crystal skull, it's entirely true and I knew a man from one old team had found a big ancient treasure which contained a crystal skull(in green color) among other unique objects it was incredibly beautiful
that never has been reflected in formal locations or museums.
the treasure was found more than 40 years ago, they sold all things except to the skull.
When I heard about Indiana IV, unconsciously remembered that.
