EileenmarksWilliam Oldroyd’s second directorial feature afterLady Macbeth. The dark psychological thriller comes as an adaptation of the eponymous debut novel byOttessa Moshfegh, published in 2015. The PEN/Hemingway Foundation-winning novel follows the story of Eileen Dunlop, told by the protagonist herself as a flashback. Set in the 1960s in a small town in Massachusetts,Eileenfollows the titular protagonist, a 24-year-old secretary at a juvenile detention center who gets enchanted by the center’s new counselor, Rebecca. Drawn by Rebecca’s glamorous personality, Eileen quickly befriends her. With Rebecca’s guidance and friendship, Eileen begins to discover new aspects of her character that would change her life forever. The book was critically acclaimed for its plot and narrative, with reviewers describing it as “playful, shocking, wise, morbid, witty, searingly sharp.” And now, the2023 film adaptationbrings the powerful story to life.
To portray Moshfegh’s gritty characters, Oldroyd has put together an equally powerful cast led byThomasin McKenzieandAnne Hathaway, among several other popular faces of the stage and screen. After all, as is evident from the original novel,Eileenis a character-driven story that explores the complexities of human relationships and the two leading ladies of the film have a resume that makes them a good fit. For instance, McKenzie’s 2021 psychological thriller,Last Night in Sohoalso shows the actor in a role where she is enamored by a dazzling singer and how that unravels her life. Similarly, Hathaway is also experienced with emotionally complex and challenging roles, whether it’s the anguished Kym inRachel Getting MarriedorEsther Graff inArmageddon Time, where she “shows all the layers of what she’s hiding underneath her smile in every scene”. As Collider’sRoss Bonaimedescribes the characters ofEileenin his review:

“McKenzie plays the timid Eileen in an understated, meek way, yet since we see her when no one else does, we know that there’s more that meets the eye with her character. It’s especially fun to watch McKenzie play off Hathaway’s Dr. St. John, a character who dominates every room she’s in, and knows fully who she is, even if the characters around her see her as a mystery.”
