This begins like a rattle of machine gun fire and never lets up, from the white on red title to the sensational series of action sequences that emboss a very modern fairytale. Hanna (the extravagantly gifted Saoirse Ronan) is being trained as a killer by her dad, incognito agent (the fantastic Eric Bana) when people come looking for them in their Nordic hideout. She goes on the run after escaping her captors led by Cate Blanchett. The trans-Europe chase takes place in spectacular fashion, hiding with an English family on holiday, having regular teenage experiences, then the chickens coming home to a grisly roost in Grimm’s playground in Berlin …This came from the brain of Seth Lochhead who did the screenplay with David Farr. It’s about breeding children in labs, family, friendship, squaring accounts, training the military and nightmarish reality versus storytelling. Ronan asked her Atonement director Joe Wright to take it on. It is spectacular from start to finish with an amazing soundtrack by The Chemical Brothers. One of my favourite films of the last decade. Really something. (Maybe you shouldn’t watch if you’re the product of IVF. Just saying).
