My theory about Indiana Jones and the Kingdom of the Crystal Skull, by the way, is that Shia LaBeouf isn't playing Indy's son at all—he's playing a younger version of Indy himself. This is vaguely supported by the fact that his character's name has not yet been officially revealed, as well as by hints from Vanity Fair and this site. Are we looking at extended flashback scenes? Time travel? The fountain of youth? Not sure—although I have a hunch that the story will involve Indy coming face to face with his younger self. And I'm willing to bet that there will be a fifth and sixth installment, and that LaBeouf will take over the role of the man in the fedora. (Of course, the Wikipedia page for the movie contradicts all of the above, suggesting that LaBeouf is playing a motorcycle-riding greaser. But what does Wikipedia know?)
