Last year it was announced that the Paula Hawkins dark thriller and best seller The Girl on the Train was going to be made into a film, and we’ve been waiting patiently to get a sneak peek. Today, a brand new trailer has been released, and we can only imagine that the film will be just as captivating.

The Girl on the Train is the story of protagonist Rachel Watson (played by Emily Blunt), who is devastated by her recent divorce and 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.

The stellar cast also includes Rebecca Ferguson, Haley Bennett, Justin Theroux, Luke Evans, Allison Janney, Edgar Ramirez, Lisa Kudrow and Laura Prepon.

If you aren’t one of the millions who have the book, you still have some time, the film will be in theaters October 7th.
