As for glam, Anne opted for a touch of rosy blush on her cheeks, and black eyeliner to highlight her magnetic gaze.

Hathaway stars alongside Thomasin McKenzie, Shea Whigham, Marin Ireland and Owen Teague in the highly-anticipated film, which follows a parasitic relationship between two workers at a juvenile detention facility.

Eileen is set in frigid 1960s Boston, following Eileen (McKenzie), who shuffles between her father’s emotionally haunted home and the prison where she works alongside colleagues who have ostracized her.

Hathaway plays Rebecca St. John, described as, ‘an intoxicating woman’ who joins the staff and Eileen becomes more and more interested in her.

Hathaway looked nearly unrecognizable in the first trailer for the movie, which was released last month.

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

The trailer begins with Eileen 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.

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.

Coming soon! Hathaway and McKenzie star as two workers at a juvenile detention facility involved in a parasitic relationship. The film is scheduled to hit theaters on December 1

It was confirmed that the novel would be adapted into a film the following year, and Hathaway and McKenzie signed on to star in the project last year.

Eileen premiered during the most recent Sundance Film Festival, which was held this past January.

The movie received widespread critical acclaim, and it currently holds an 89% rating on Rotten Tomatoes.

Eileen’s wide release in the United States is scheduled to commence on December 1.
