Prometheus

37 years before the events of Alien a British billionaire funds an expedition into the depths of space to discover the true origins of humanity. Led by a pair of loved-up scientists who find clues of an Alien intelligence and peopled by the usual odd assortment of odd-bods who aren't quite sure what they're getting themselves into, this is proper science fiction full of stunning sets and big ideas. The biggest, boldest, bravest movie of the summer takes us back before the start of the Alien saga to answer the question 'Why are we here?'.
