Emily Blunt Is Embroiled in a Mystery in the First Trailer for The Girl on the Train

The first trailer for The Girl on the Train has arrived, and it should satisfy anyone who has been waiting for a psychological thriller to follow the example set by the 2014 adaptation of Gillian Flynn’s Gone Girl. Adapted from Paula Hawkins’ best-selling 2015 novel of the same name—the film rights for which were acquired even before the book was published—the movie stars Emily Blunt as the titular girl on the train.

Blunt plays Rachel, a divorced woman who passes the home of her ex-husband (Justin Theroux) and his new wife (Rebecca Ferguson) on her way to work each day. She becomes fascinated by another couple a few doors down, but soon becomes embroiled in a mystery that follows the disappearance of the woman upon whom she’s been spying.

The movie, directed by Tate Taylor (best known for The Help), looks at first glance to be a worthy addition to Blunt’s steady output of solid performances, most recently as an FBI agent in Sicario.

The Girl on the Train hits theaters on Oct. 7.
