Harrison Ford is joined by Cate Blanchett, Shia LaBeouf and Karen Allen from Raiders for the fourth film in Steven Spielberg’s action-adventure franchise, co-written by George Lucas. It’s 1957 and Indy just can’t help but get caught up in the Cold War as the Soviets try to harness the power of some odd-looking and strangely alluring crystal skulls to use it against the West. As the film opens, a bunch of Soviets break into a nuclear testing facility in Nevada and in the boot of one of their vehicles are… Indiana Jones (Ford) and his mate Mac (Ray Winstone). Then up turns Irina Spalko (Blanchett), all sinister black bob and Eastern European accent, and begins trying to extract information from our hero about a mysterious object. As they go into a massive warehouse, the incidental music from Raiders pipes up. Yes, it’s the warehouse… with all the boxes… where they put the Ark of the Covenant. Anyway, enough nostalgia. The Russians are looking for a crate and in that crate is a body. And the crate is stamped Roswell. Get the picture? Indy, of course, escapes and then survives a nuclear blast. That’s just the opening scene. Anyway, then a kid called Mutt Williams (LaBeouf) comes to Indy to tell him that his old friend and colleague, Professor Oxley (John Hurt) has disappeared while attempting to escort a crystal skull to the mythical city of Eldorado. Indy describes a legend that says whoever returns the skull to Eldorado will be given control over the city’s power. But surely Eldorado doesn’t exist and, even if it did, why would Oxley be involved in returning the skull?
