Inspired by a real-life sting operation in Australia, The Stranger changes the names and some of the circumstances to come in close to some truly disturbing characters. Sean Harris is embodiment of ordinary evil and Joel Edgerton easily matches him as the undercover cop who has to befriend him in order to gain his trust enough for him to confess to the murder of a young teenager. The poise and build up is expert and it's an upsetting film that works its spell because all the elements dovetail to create one of the darkest and disturbing films to enter into the mind of a killer. There is no violence in this film, or action. It's all in the mind. A future drama classic.
Currently this is only streaming on Netflix but hoipefully it will receive a physical DVD / Bluray / 4K release at a later date.
