Earlier this year it was confirmed that Tate Taylor, the same director behind the Oscar-winning film, “The Help,” would direct the film-adaptation of “The Girls on the Train.” Now, it seems that DreamWorks has narrowed down its list of leading ladies, and Emily Blunt has been reported to be in talks for the role.

DreamWorks acquired the rights to Paula Hawkins’ debut thriller in 2014, prior to the novel’s publication, and set Erin Cressida Wilson to adapt for the screen. Marc Platt will produce the film, while Jared LeBoff of Marc Platt Productions will serve as executive producer. In “The Girl on the Train,” Rachel, who is devastated by her recent divorce, spends her daily commute fantasizing about the seemingly perfect couple who live in a house that her train passes every day, until one morning she sees something shocking happen there and becomes entangled in the mystery that unfolds.

“Bringing rich material to the screen in the filmmaker friendly environment DreamWorks provides is a director’s dream,” said Tate Taylor during her directing announcement. “I’m honored to be a part of this.”

“The Girl on the Train,” is the fastest selling adult novel in history with over two million copies sold in the United States alone since it was published in January by Riverhead Books. It landed in the top spot on the New York Times bestsellers list its first week and has remained on the list for over 17 weeks straight.
