After first appearing on British screens last year in the ITV mini series HIM, British actor Fionn Whitehead is now set to be catapulted to Hollywood stardom.

From working in a coffee shop in Waterloo, London, to receiving praise from the Screen International’s Stars of Tomorrow 2016 and being signed by US agency United Talent Agency, the Londoner looks poised to become one of the biggest breakout stars of the year as he stars as Tommy in Christopher Nolan’s hotly-anticipated WWII film Dunkirk, released July 21. Following his big screen debut, Whitehead will next be seen in another major lead role opposite Emma Thompson and Stanley Tucci in the drama The Children Act, an adaptation of Ian McEwan’s novel in theatres later this year.
