MJ Delaney’s film is a frank portrayal of female friendship.

Writer Rachel Hirons, and director MJ Delaney, describe ‘Powder Room’ - an all British and all female production –  “an antidote to all those types of films that don’t pass the Bechdel test”.

The Bechdel test gauges the active presence of well-rounded female characters in Hollywood films by asking whether they feature at least two prominent women characters shown talking to each other about something other than a man.

Powder Room, which is due for release on December 6, passes with flying colours.

The film follows Sam (Sheridan Smith) as her life unravels on a night out, telling her story in a series of vignettes that show conversations held in a nightclub toilet.

In an interview for Screen Daily, Hirons explained that the story was inspired by a night out during which she overheard a candid conversation between two women in a toilet cubicle.

“During their conversation my faith in women – which had recently been shaken by a friend who claimed that women don’t dress for men but for other women as a form of competition – was restored.

“It made me want to show women as they really are, in an unedited form. There is something beautiful in portraying the truth.”

Powder Room is the directorial debut of Delaney, a 25 year-old who gained an internet following through viral videos such as ‘Newport State of Mind’.

In a recent question and answer session Delany said that she was attracted to Hiron’s original stageplay primarily due to its ‘truthful and honest’ portrayal of female friendships.

In a live question and answer session, actress Jaime Winstone said of her character Chanel: “It’s nice to see a young girl who is confident and sexual without being portrayed badly.”

As well as being written and directed by women, the cast of Powder Room represents a powerhouse of young female acting talent.

Winstone and Smith are joined by experienced actresses Oona Chaplin and Riann Steele, while Kate Nash’s appearance marks the singer’s third feature film.

Meanwhile the music for the film was curated by the all-female, five-piece rock band ‘Fake Club’.

Discussing the effects of social media on young women – an issue that Powder Room addresses, Smith said: “All girls have insecurities and fears.

“I look on Facebook and see that all my friends from school have got kids and I’m like ‘Wow – that’s amazing! You’ve brought kids into the world…and I’m just pretending to be other people!’”

Delaney concurred, saying that she wanted Powder Room totackle “the challenge of this whole new aspect of our lives online”; while we are constantly bombarded by “Instagram feeds of the perfect existence”, nobody is as happy as they portray themselves to be.

Powder Room will be released on 6 December.
