Fionn Whitehead was an English actor born on July 18, 1997 in London, England. Named after Irish folk legend Fionn mac Cumhaill, Whitehead grew up in an artistic household. His father, Tim Whitehead, was a jazz musician while one of his elder sisters, Hattie Whitehead, played folk music. He recalled wanting to be a guitarist, rugby player, or breakdancer growing up, but started to take acting classes at the Orange Tree Theatre at age 13. Whitehead attended Richmond College, and made his acting and TV debut as the star of the drama mini-series "Him" (ITV, 2016), in which his titular character realizes he has telekinetic powers. His big break, however, came when he was cast in Christopher Nolan's World War II drama film "Dunkirk" (2017), Whitehead's film debut; he was working at a coffee shop in Waterloo before starring in the film. With the film and his performance critically praised, Whitehead was attached to a number of upcoming projects, including "The Children Act" (2017); he starred alongside Emma Thompson and Stanley Tucci.
