Development In June 2012, the original screenplay written by Irena Brignull was presented to the
British Film Institute (BFI). Funding for the project was thereafter secured from the BFI Film Fund and
Creative Scotland. The initial
production budget in 2015 was £5 million. In May 2017, the producers announced that Holliday Grainger was to star in the film. In August 2017, Anna Paquin joined the cast as Doctor Jean Markham. Unlike the novel, which is set in
Yorkshire, the film takes place in southern
Scotland. Film Constellation handled international distribution rights. The North American rights were acquired from Film Constellation by Good Deed Entertainment on 30 October 2018. Distribution rights for Germany, Spain, Korea, and Taiwan were sold on 4 November 2018, followed by rights to Australia, New Zealand, Scandinavia, and Poland on 7 February 2019, as well as acquisition by Vertigo Releasing for the United Kingdom.
