"Eye of the Tiger" your favourite? Wow...Interesting. One notable
Indy connection is that both "Last Crusade" and EOTT have location
shots from Petra in Jordan. (In particular, the Khazneh temple/tomb
where I think you've visited, Canyon).
Another Lucas connection: Peter Mayhew was the stand-in
for the Minoton/minotaur.
As for skeletons being a great enemy...Do you have the Marvel
comic series? #33 & #34 have Indy struggling with sword-wielding
skeletons who rise from the ground, in a scene seemingly inspired
by "Jason & Argonauts"!
