Anne Hathaway looked nearly unrecognizable in the first trailer for the upcoming psychological thriller Eileen that was released Tuesday.

In the clip, the 40-year-old performer dons a retro  blonde wig as she portrays a prison psychologist who draws a young secretary into an unsteady relationship.

Hathaway — who recently reunited with her The Devil Wears Prada costar Meryl Streep — stars alongside Thomasin McKenzie, Shea Whigham, Marin Ireland and Owen Teague in the highly-anticipated film.

The trailer begins with Eileen, played by actress McKenzie, patting down her prison’s staff members and gazing at an attractive prisoner.

The character then tells her father that she had experienced ‘one of those days you never forget’ before she first sees Rebecca, played by Hathaway.

Storyline: In the clip, the 40-year-old performer was nearly unrecognizable while wearing a blonde wig as she portrayed a prison psychologist who draws a secretary into an unsteady relationship

Stacked cast: The actress, who recently reunited with her The Devil Wears Prada costar Meryl Streep, will also star alongside Shea Whigham, Marin Ireland and Owen Teague in the upcoming movie

Eileen and Rebecca establish an instant connection after the psychologist is introduced to the prison’s workers, and after introducing McKenzie’s character to cigarettes, the latter ominously states: ‘I live a little differently than most people.’

After Hathaway’s character establishes a close relationship with the secretary, she places her hand on the latter’s thigh before they dance with one another during a trip to a bar.

Eileen later tries to leave Rebecca’s house before the latter slams the front door shut and ominously states: ‘You can never tell anyone, do you understand? Promise me.’

The secretary’s father, played by Wigham, then states that he could imagine his daughter with a gun, she points one at Rebecca, who calmly remarks: ‘That’s very good, Eileen.’

Wigham then tells his daughter that she is ‘different these days. Almost interesting.’

A rapid-fire montage then ensues, which concludes with Rebecca locking lips with Eileen, after which she remarks: ‘The only way out’s for someone to die.’

The trailer ends after Hathaway’s character opens a bottle of wine by hitting its bottom against a wall, much to the secretary’s surprise.

Eileen is based on the 2015 novel of the same name, which was written by Ottessa Moshfegh, who also co-wrote its script alongside her husband, Luke Goebel.
