Nearly 20 years after riding his last Crusade, Harrison Ford makes a welcome return as archaeologist/relic hunter Indiana Jones in Indiana Jones and the Kingdom of the Crystal Skull, an action-packed fourth installment that's, in a nutshell, less memorable than the first three but great nostalgia for fans of the series. Producer George Lucas and screenwriter David Koepp (War of the Worlds) set the film during the cold war, as the Soviets--replacing Nazis as Indy's villains of choice and led by a sword-wielding Cate Blanchett with black bob and sunglasses--are in pursuit of a crystal skull, which has mystical powers related to a city of gold. After escaping from them in a spectacular opening action sequence, Indy is coerced to head to Peru at the behest of a young greaser (Shia LaBeouf) whose friend--and Indy's colleague--Professor Oxley (John Hurt) has been captured for his knowledge of the skull's whereabouts. Whatever secrets the skull holds are tertiary; its reveal is the weakest part of the movie, as the CGI effects that inevitably accompany it feel jarring next to the boulder-rolling world of Indy audiences knew and loved. There's plenty of comedy, delightful stunts--ants play a deadly role here--and the return of Raiders love interest Karen Allen as Marion Ravenwood, once shrill but now softened, giving her ex-love bemused glances and eye-rolls as he huffs his way to save the day. Which brings us to Ford: bullwhip still in hand, he's a little creakier, a lot grayer, but still twice the action hero of anyone in film today. With all the anticipation and hype leading up to the film's release, perhaps no reunion is sweeter than that of Ford with the role that fits him as snugly as that fedora hat. --Ellen A. Kim
