just myself, darlin'; sometimes that's the only important person. BUT, back on topic, the original Indy 4 was supposed to be "Indiana Jones and the attack of the Moon Men". ¡gawd, would THAT have sucked!
I think he went to the Moon and tried to find them.
The entire movie is Harrison Ford in a 50's Space Suit / Diving Bell with a really long hose connecting him back to earth wandering around going, "Mooooooooooooooooooooooooooooooooon Men? Moooooooooooooooooooooooooon Men? Where are you?"
