Indiana Jones and the Kingdom of the Crystal Skull2008

Mutt:
What is it [the crystal skull]?

Indy:
Deity carving. Mesoamerican. There are a number of crystal skulls in the world; I saw one in the British Museum. Interesting craftsmanship, but that's about it.

Mutt:
Well, laugh if you want. Oxley said he found it this time. He said this was real and he was off to a place called Akator with it.

Indy:
Akator? He said that? You're sure?

Mutt:
That's what he said, he said Akator. What is it?

Indy:
It's a mythical lost city in the Amazon. Conquistadors called it El Dorado. Supposedly, the Ugha tribe were chosen by the gods 7000 years ago to build a giant city out of solid gold. It had aqueducts and paved roads and technology that wouldn't be seen again for 5000 years. Francisco de Orellano disappeared into the Amazon looking for it in 1546. I almost died of typhus looking for it myself. I don't think it exists.

Mutt:
Why would Ox want to take the skull there?

Indy:
The legend says that a crystal skull was stolen from Akator in the 15th or 16th century, and that whoever returns the skull to the city temple will be given control over its power.
