I was settling in for what looked like a bit like a police procedural – more suited to the small screen than the big. Then, about half an hour into ‘Headhunters’ it all went mental. You were at the protagonist’s side as he tried to figure out what was going on and were complicit in his mistakes. This lasted until the final twist, when the audience were only half in on the plot. A very satisfying film. I haven’t read the Jo Nesbo book it is based on but if it is as immersive as the film, I might just add it to my ‘must read’ list.
