A young American in Taipei (Scarlett Johansson), coerced into serving as a drug mule for gangsters, accidentally absorbs a powerful new product that unlocks 100 percent of her brain capacity, turning her into a superhuman being and an ass-kicker extraordinaire. No one has ever accused French action director Luc Besson of thinking too hard, and this frantic exercise in pseudoscience and goofball metaphysics is best enjoyed by following his lead. The title refers not only to the main character but also to the famous fossilized skeleton, an ancestor of Homo sapiens; Besson implies that both represent the birth of a new species, turning this enjoyable shoot-’em-up into a dumbbell 2001: A Space Odyssey. With Morgan Freeman and Choi Min-sik.
