As one-fifth of the British pop group One Direction, Harry Styles, together with former member Zayn Malik, Liam Payne, Louis Tomlinson, and Niall Horan earned five BRIT Awards, three NME Awards, and two American Music Awards, and sold several platinum records and sold-out world tours. The five-piece became a group of four in 2015, when Malik departed the band. Despite this, the group continued on until their hiatus in 2016. Since then, each band member has gone on to release their own solo records, including Styles, who released his self-titled debut this May.

But aside from making music, Styles has also tried a hand in acting, appearing in the new Christopher Nolan film, "Dunkirk."

Harry Styles as Alex in 'Dunkirk'

The 23-year old One Direction band member auditioned for the role of Alex in Christopher Nolan's "Dunkirk." Alex is a British soldier amidst the Allied soldier's evacuation from Dunkirk, France. Styles landed the role not because of his fame, but because his talent. In fact, Nolan recently shed light on how Styles was cast in his film. In speaking to The Hollywood Reporter, Nolan explained that he wasn't truly "aware...of how famous Harry was" during the casting process. The 46-year old director admitted that his daughter and his children did speak of Styles a lot because they knew him from One Direction, but he said that "I cast Harry because he fit the part wonderfully and truly earned a seat at the table."

Mark Rylance wasn't aware of Harry Styles' popularity

"Dunkirk" actor Mark Rylance, who plays mariner Mr.

Dawson in the film, was also unaware of just how much of a household name Harry Styles was. In fact, he also found out about Styles through his young niece. Both Rylance and Christopher Nolan were oblivious to Styles' popularity, but it seems that it had worked in the singer's favor. As the film is set to hit theaters this July 21 in North America, Styles is also hitting the road to promote his self-titled debut record across 56 venues.
