Calendar Girls is a 2003 British comedy film directed by Nigel Cole. Produced by Touchstone Pictures, it features a screenplay by Tim Firth and Juliette Towhidi, based on a true story of a group of middle-aged Yorkshire women who produced a nude calendar to raise money for Leukaemia Research (subsequently Blood Cancer UK) under the auspices of the Women's Institutes in April 1999 after the husband of one of their members dies from cancer. The film stars an ensemble cast headed by Helen Mirren and Julie Walters, with Linda Bassett, Annette Crosbie, Celia Imrie, Penelope Wilton, Geraldine James, Harriet Thorpe and Philip Glenister playing key supporting roles.

Calendar Girls premiered at the Locarno Film Festival and was later shown at Filmfest Hamburg, the Dinard Festival of British Cinema in France, the Warsaw Film Festival, the Tokyo International Film Festival and the UK Film Festival in Hong Kong. It garnered generally positive reactions by film critics, who compared it with another British comedy film The Full Monty (1997). At a budget of $10 million it also became a major commercial success, eventually grossing $93.4 million worldwide following its theatrical release in the U.S. In addition, the picture was awarded the British Comedy Award for Best Comedy Film, and received ALFS Award, Empire Award and Satellite Award nominations for Mirren and Walters, and a Golden Globe Award nomination for Mirren.
