Emily Blunt and Rebecca Ferguson will star in the film adaptation of the hit novel.

DreamWorks' adaptation of the bestselling book The Girl on the Train will hit theaters Oct. 7, 2016.

The announcement came hours after The Hollywood Reporter revealed that Justin Theroux is in talks to join the cast after Chris Evans' deal to star never came to fruition because of scheduling issues.

Emily Blunt, Rebecca Ferguson, Jared Leto, Haley Bennett and Edgar Ramirez are all attached to the film. Blunt plays a troubled woman (an alcoholic whose husband left her for his mistress) who becomes fascinated by a seemingly perfect couple whose home she passes while riding the train. But after she thinks she witnesses a murder, she begins to realize that she may have been involved in the crime.

Theroux will play Tom, the woman's ex-husband.

Paula Hawkins' best-seller hit shelves in January 2015 and has sold more than 3 million copies in the U.S.
