Harry Styles described the central theme of his new film My Policeman as “wasted time”.The Michael Grandage-directed film (based on the novel by Bethan Roberts) sees Tom (Styles), a 1950s English policeman, enter into a love triangle with his lover, museum curator Patrick (David Dawson) and wife, schoolteacher Marion (Emma Corrin). Flashing forward to the 1990s, the trio (played by Linus Roache, Rupert Everett and Gina McKee, respectively) attempt to repair their interpersonal damage from 40 years prior.Styles attended the My Policeman premiere at the Toronto International Film Festival last night (September 11).
