The Girl On The Train trailer: Emily Blunt is 'afraid of herself' in first seductive sneak peek

The first official trailer for upcoming mystery thriller The Girl On The Train, which is based on the international bestselling novel of the same name and stars Emily Blunt, has been released by Entertainment One UK.

While the sneak peak, which is set to a slowed-down version of Kanye West's Heartless, doesn't give much away it does give an indication of the dramatic and slick tone the film that is being dubbed the next Gone Girl will adopt. However, it does warn us to expect sex, violence, heightened emotions and a very dark tale of adultery, alcoholism and abuse.

In the film, based on a book by Paula Hawkins, Blunt plays divorced drunk Rachel Watson, a woman who commutes to the city every day, to keep up the illusion that she has a job to go to – just so her housemate doesn't realise that she has been unemployed for the past few months.

During her monotonous journey, she becomes obsessed with a couple that she sees every day as the train passes their home and begins dreaming about their lives and trying to find out more about them.

However, one fateful day, her voyeurism takes on a darker tone after a young woman (Music and Lyrics' Haley Bennett) goes missing and Rachel becomes convinced that she's witnessed her murder while on her way into the city. As the story gets dangerously close to Rachel, she soon becomes entangled in the ensuing investigation, trying to figure out what really happened, if her regular blackouts mean that she's involved or even whether it's all just a figment of her imagination. At one point she reveals: "I'm afraid of myself."

Starring alongside Blunt and Bennett are Justin Theroux, who plays Rachel's ex-husband Tom, Rebecca Ferguson who portrays Tom's current wife Anna, Luke Evans and Allison Janney. Edgar Ramirez, Orange Is The New Black star Laura Prepon and Lisa Kudrow also appear.

Tate Taylor (The Help) is directing the adaptation, while Chloe, and Men, Women & Children screenwriter Erin Cressida Wilson has written the script. The eagerly-anticipated movie is due to be released in both the UK and the US on 7 October 2016.
