On Wednesday, Universal released the first trailer for The Girl on the Train, the movie adaptation of the popular novel by Paula Hawkins. It's a thriller and a mystery wrapped in a story of broken relationships and damaged people; Hawkins's book has sold more than 3 million copies in the US.
The trailer is dark — even the shots that take place in daylight are shivery and dim. Emily Blunt's Rachel, one of the main characters, is the last person to see a woman who we later find out disappeared. Then, mixed in with various shots of crime scenes, foreplay, and violent hair pulling, we find out that neither Rachel nor the woman she saw are who we think they are.
The Girl on the Train hits theaters on October 7.
