Paramount Pictures has revealed another Indiana Jones and the Kingdom of the Crystal Skull poster over at USA Today, in lieu of this week's ShoWest convention. Take a look:

The new poster for Indiana Jones and the Kingdom of the CrystalSkull confirms something alien is afoot.

The first poster for the film (due May 22) featured part of the title relic, but there was always something odd about the eye socket. In the follow-up, also by sci-fi/fantasy movie artist Drew Struzan, it's clear the skull is not at all human. Add to that the recent trailer, with its shot of a crate labeled "Roswell, New Mexico 1947," and you don't need to be a professor of archaeology to put the pieces together.

Other clues: Looks as if our hero will face his least-favorite animal and the locals at some Maya ruins. Karen Allen (who also was in 1981's original) seems to be enjoying herself, though.
