It is an adaptation of Octave Mirbeau's 1900 novel of the same name and stars Léa Seydoux as Célestine, a young and ambitious woman who works as a chambermaid for a wealthy couple in France during the early twentieth century.

It was screened in the main competition section of the 65th Berlin International Film Festival[7] and was released on 1 April 2015, by Mars Distribution.

[8][9] In Normandy at the end of the 19th century, a beautiful and ambitious young chambermaid named Célestine (Léa Seydoux) enters the service of her new employers, the Lanlaire family, which consists of a bitter wife and her perverted husband.

She also meets the other servants: Marianne, the overweight and homely cook, and the mysterious, older Joseph (Vincent Lindon), the groom, who shares a mutual attraction with Célestine.

Throughout the film, Célestine reflects on her past positions, such as a middle-aged woman with an elderly husband who was humiliated at a train customs stop after being forced to open a box revealing her dildo.

The next day, she visits Joseph and learns that he is a rabid anti-Semite and propagates anti-Dreyfus propaganda on behalf of local priests.

He dreams of owning a business where he can provide a rendezvous for militant right-wing nationalists and acknowledges that he needs a woman like Célestine to make his plan a success.

[4] In February 2013, Marion Cotillard was in talks to play the central character Célestine, but later dropped out of the film over scheduling conflicts with Macbeth.

[10][11] On 5 February 2014, director Benoît Jacquot confirmed in an interview Diary of a Chambermaid will begin shooting in the forthcoming summer, with Léa Seydoux and Vincent Lindon joining the cast of the film.

Club's Ignatiy Vishnevetsky opined that the film "lacks a unifying principle, as though the director were too eager to address subtexts to bother with text," and concluded: "Nominally, Diary Of A Chambermaid is about the moral rot hiding below, but its most lasting impressions come from surface pleasures and barely motivated flourishes of style.
