It's been a few years since the last adventure--for us as well as for Indy. It's now the '50s and our aging adventurer is called upon to engage in one last globe-hopping trek. Teaming up with a James Dean wannabe (Shia LaBeouf) and his ex-girlfriend Marion Ravenwood (Karen Allen), Indy travels to South America to foil an evil Soviet plot. Seems the Russkies are trying to get their hands on a mysterious collection of ancient crystal skulls that might (possibly, maybe, who knows?) hold proof of extraterrestrial life. 120 minutes PG-13.
