Taken on set, the photos show the British singer-songwriter in full navy police uniform as the film’s lead character, Tom, alongside David Dawson as his love interest Patrick.
Based on the critically-acclaimed gay novel of the same name from Bethan Roberts, My Policeman follows a schoolteacher called Marion who falls in love with Tom in 1950s Brighton.
Marion will be played by Emma Corrin, who recently earned a Golden Globe Award for her performance as Princess Diana in The Crown.
After meeting museum curator Patrick, however, Tom finds himself torn between both lovers. Due to social constraints of the era, Tom decides that it is safer to marry Marion.
