Indiana Jones returns May 22 in the long-anticipated film "Indiana Jones and the Kingdom of the Crystal Skull." Indy, of course, is not just a globetrotting adventurer but also an archaeologist.

In most of the Indiana Jones films, the stories by George Lucas involve some mysterious, long-lost artifact. In "Raiders of the Lost Ark," it was of course the Ark of the Covenant; in "Indiana Jones and the Last Crusade," it was the Holy Grail.
