Wicked Little Letters is a 2023 British black comedy mystery film directed by Thea Sharrock, written by Jonny Sweet and starring Olivia Colman, Jessie Buckley, Anjana Vasan, Joanna Scanlan, Gemma Jones, Malachi Kirby, Lolly Adefope, Eileen Atkins and Timothy Spall.

[6][7][8][9] Wicked Little Letters premiered at the Toronto International Film Festival on 9 September 2023, and was released in the United Kingdom by StudioCanal on 23 February 2024.

In 1920, Edith Swan, a devout Christian in Littlehampton, becomes the target of hate mail, an issue of great distress to her controlling father Edward and gentle mother Victoria.

This was followed by a visit from the local child protection services acting on a tip; believing Edith had called them, Rose ended the friendship.

While concluding the police formalities, Gladys notices similarities between Edith's signature and the letters; again, her claims are dismissed by Spedding, who suspends her from duty.

A textual epilogue reveals Edith was sentenced to twelve months hard labour, Rose was never accused again, and Gladys was commended for her actions.

[11] In September, the cast was rounded out with Anjana Vasan, Timothy Spall, Gemma Jones and Eileen Atkins among the additions.

[12] Production began in September 2022 and continued till early October in Arundel and Worthing, with some scenes filmed in and around the former Crown Court in Aylesbury.

The website's consensus reads: "Thanks largely to a strong cast that leans into the story's humorous side, Wicked Little Letters is a diverting comedy even if the mystery at its core isn't particularly clever.

[24] Richard Roeper of the Chicago Sun-Times gave the film three stars out of four and wrote, "The chief delight in Wicked Little Letters is watching Colman and Buckley in action; it's really not much of a mystery, as the culprit is revealed to us long before the townsfolk catch on.
