Thanks to Edge of Tomorrow, Sicario, and the upcoming Huntsman: Winter’s War, Emily Blunt is no stranger to playing action-heavy badasses. But her role as the titular Girl on the Train, she said, is “the most challenging thing I’ve ever done.”
Speaking with Deadline, the Golden Globe winner said she was pulled into the story’s “very damaged” protagonist. “I just love that it’s about addiction and loneliness and voyeurism and what we think we see and don’t see. I think it’s very relatable. We’ve all ridden the train to work and wondered about the lives of the people on the train, and I think that people relate to that.”
The film, based on the best-selling novel by Paula Hawkins, sees Blunt as Rachel Watson. Coping from the pain of her divorce with alcohol, she forms a fictional bond with a couple she sees out the window of her train commute. One day, she sees something shocking and becomes entwined with the mystery that follows.
“I love that your heroine, your lead character is the most unreliable witness in the world because she’s a drunk,” Blunt continued. “And yet she’s right, and nobody believes her. The idea of playing a part like that where you just feel like you’re drowning is exciting. I’ve never played a blackout drunk before, so this is new to me now.”
In EW’s exclusive first look at the film, director Tate Taylor remarked, “You can’t avoid the puns with this movie — she’s a train wreck.”
Blunt is joined by Rebecca Ferguson (Mission: Impossible – Rogue Nation), Haley Bennett (The Equalizer), Justin Theroux (The Leftovers), Luke Evans (Fast & Furious 6), Allison Janney (Mom), Edgar Ramirez (Joy), Lisa Kudrow (The Comeback), and Merritt Wever (Nurse Jackie).
The Girl on the Train debuts in theaters on Oct. 7. Head to Deadline for more from Blunt’s interview.
