Harry Styles and Emma Corrin Are Set to Headline the Cast of My Policeman

Styles will star as the "policeman" in the title. In the 1950s, Tom marries a woman, Marion, despite being in love with Patrick, a man he meets at a museum. For a while, he's "shared" by his wife and his lover until something terrible happens that breaks them apart.

Although Styles is, of course, best known for his recording career, this isn't his first acting gig. In 2017, he made his film debut in the WWII drama Dunkirk, and he was recently cast to replace Shia Labeouf in Olivia Wilde's Don't Worry Darling, a '50s-set psychological drama co-starring Florence Pugh, Chris Pine, and Wilde herself.

Corrin is set to play Marion, a woman in the 1950s who falls in love with policeman Tom and marries him. She's fully aware of his simultaneous relationship with another man, as well as the fact that her husband isn't really in love with her in return.

The actress is a newly-minted Golden Globe nominee for her work as Princess Diana in the fourth season of The Crown. Before she tackled that iconic role, she had mostly done guest roles on TV and a few small movies; her biggest credit was Misbehaviour, a comedy about pageant queens co-starring Keira Knightley, Gugu Mbatha-Raw, Jessie Buckley, and Keeley Hawes.
