Paula Hawkins's bestseller The Girl on the Train is this year's Gone Girl [1], and it's also going to be adapted into a movie soon [2]. The Help's director, Tate Taylor, will helm the mystery, which revolves around a woman (OK, a girl) whose obsession with a couple she sees on her daily commute may be more insidious than it seems. Emily Blunt [3] is playing the lead, the other lead actresses and actors have been cast, and now, a familiar Friend and another male lead have joined the cast. If you're at all concerned that the Americans will have trouble mastering British accents, take heart: the movie will be set in New York now, rather than London. Find out everything else you need to know about this hot adaptation [4], and see the first pictures from the set [5] after you check out the cast.
