Eileen is a 2023 psychological thriller film directed by William Oldroyd, based on the 2015 novel by Ottessa Moshfegh, who co-wrote the screenplay with her husband, Luke Goebel.

At home, she lives with her widowed and alcoholic father, Jim, a former chief of police who suffers from paranoia and is emotionally abusive towards her.

As she cleans her vomit from the seat of her car, a local policeman arrives to inform her that the neighbors have raised complaints about Jim's violent and erratic behavior.

Rebecca does not show up, and as dawn breaks, Eileen drives to a remote forest and leaves the still-drugged Anne in her car, which fills with engine smoke.

In August 2016, it was revealed that Erin Cressida Wilson was adapting the novel Eileen by Ottessa Moshfegh for Fox Searchlight and producer Scott Rudin.

The mayor of Metuchen, New Jersey, Jonathan Busch, first confirmed that Anne Hathaway, Thomasin McKenzie, and Shea Whigham would have roles in the film.

It was confirmed that Owen Teague and Marin Ireland had been added to the cast and that Endeavor Content and WME Independent were selling distribution rights.

The website's consensus reads: "Anne Hathaway and Thomasin McKenzie prove a well-matched duo in Eileen, which honors its source material with a twisty tale of obsession.

"[26] Metacritic, which uses a weighted average, assigned the film a score of 72 out of 100, based on 44 critics, indicating "generally favorable" reviews.

[27] Following its premiere at Sundance, David Rooney of The Hollywood Reporter called Eileen "a film both malevolent and playful, morbidly funny and disturbing", commending the screenplay, direction, cinematography and cast performances.

[28] In his review for IndieWire, Ryan Lattanzio called it a "perverse folie à deux" and lauded the "immensely detailed" direction and cinematography, as well as the "career-best" performances of the leads.

[31] In her review for Vox, Alissa Wilkinson remarked: "Eileen is the kind of drama that feels like it’s got dirt beneath its fingernails […] [It] is dank and disturbing and, when you’re in the mood for something that will mess you up, exactly right".

[32] Conversely, Benjamin Lee of The Guardian admired Hathaway's "pitch-perfect" performance, but revealed that he found himself "craving a little bit more oddity from a film, and characters, that hinted at a more daring and depraved destination".
