Obsessed with The Girl on the Train [1]? We don't blame you. The book is an outstanding crime thriller [2], and we have faith that the movie adaptation will be great too. There's an impressive cast [3] lined up, including Emily Blunt [4] as Rachel, the aforementioned girl on the train who finds herself smack in the middle of a mystery. Now that the movie is filming, we have cast shots of Blunt in character and the first look at Justin Theroux as Tom. Take a look, and make sure you know all the details we have about the movie [5] so far.

Emily Blunt [6], who stars as lead character Rachel, first started shooting the film in early November.

Justin Theroux — who plays Tom, the ex of Emily Blunt [7]'s character — was first spotted on set bundled up in November.
