Paula Hawkins’ psychological thriller The Girl On The Train was one of the literary hits of 2015, landing on numerous bestseller lists and drawing comparisons to Gillian Flynn’s smash hit Gone Girl with its tale of infidelity, obsession, and a young woman who mysteriously disappears. The Help director Tate Taylor is currently working on a film version of Hawkins’ book, with Emily Blunt as Rachel, an unstable alcoholic who believes she witnesses a woman played by Haley Bennett being attacked one day from the train. Did Rachel really see something? Is there some connection to the ex-husband she frequently calls and harasses? Will we eventually get a team-up movie between Alison Janney’s hard-eyed detective and the one Kim Dickens played in David Fincher’s 2014 film?
