Scarlett Johansson stars in this bonkers sci-fi film from Luc Besson about a young woman who has an experimental drug surgically implanted into her body with the intention of her becoming a living drug mule. The drug, however, leaks into her bloodstream and gives her superpowers and allows her to use more brain capacity than is thought possible. Yes, it's absolutely nuts - but it's a cracking amount of fun if you can go along with it.
