London-based journalist turned author Paula Hawkins published the book in January 2015 as her first novel. It had sold 1 million copies by the end of March and stayed atop the UK best-seller list for a staggering 20 weeks - the longest of any book. Ever. It's the story of an alcoholic woman in early 30s who is having a pretty trying time who witnesses something from her train window during the morning commute and gets drawn into an ever more complicated world.
As is the way of things, the movie rights to the book were actually sold long before it reached shelves and production is already ramping up. Emily Blunt has been mooted for the lead role of Rachel and we're hearing more casting news now in the form of Rebecca Ferguson.
Deadline has the news that the 31 year old Swedish actress - who recently impressed in Rogue Nation - is deep in negotiations to play the part of Anna in the upcoming adaptation. It's a critical role in the film and a great move for the actress as she peppers her CV with roles in period, action, drama and now thriller pieces.
The story has been likened to Gone Girl and with this popular success of the novel it's likely to earn a lot of media attention as the film nears its release date. The Help director Tate Taylor is at the helm and Erin Cressida Wilson is writing the script.
