The first trailer for The Girl on the Train starring Emily Blunt as a mysterious commuter, has arrived online.
The trailer, which first debuted at CinemaCon earlier this month, shows Blunt's Rachel as she becomes swept up in a mystery involving her ex-husband (Justin Theroux)'s missing nanny.
Rachel is lonely, alcoholic divorcee, whose train passed her old home -- where her ex-husband and his new wife live -- every day. She begins to spy on a couple a few houses down, played by Luke Evans and Haley Bennett. Once a mysterious disappearance occurs, Rachel gets more and more involved with their lives.
The trailer is backed by a soundtrack of Kanye West's Heartless. Laura Prepon, Rebecca Ferguson, Edgar Ramirez, Allison Janney and Lisa Kudrow also star.
The trailer first arrived online on Tuesday, but was taken down by Universal Pictures and released officially the next day.
The Girl on the Train, adapted from Paula Hawkins' best-seller and directed by Tate Taylor, hits North American theatres on Oct. 7. The film is yet to be scheduled for release in Australia.
