The Stranger snuck onto Netflix with minimal fanfare the same way it stalks its way into viewers' minds, leaving lingering chills and a lasting impression well after the credits roll. This serial killer movie is based on a true story, where a person of interest (named Henry Teague in the film and played by Sean Harris) was suspected of abducting a child and the Australian police force launched a sting operation to coax out a confession. The true story is horrifying enough, but director Thomas M. Wright's film is a masterclass in dread, allowing the creeping feeling to pervade each element of the narrative, atmosphere and characters. Joel Edgerton also joins the cast as undercover cop Mark, who works closely with Henry, delivering a haunting performance that adds to how a crime can impact anyone associated with it.
