Kit Harington, better known as Jon Snow — he of the dour look on Game of Thrones — will star in the BBC Films production of Vera Brittain’s memoir, Testament of Youth. Harington plays Brittain’s (Alicia Vikander) love interest, Roland Leighton. She’s a pacifist and feminist, and he’s a young man who feels it’s his duty to go fight the Germans in World War I. More important, though, in order to fit into early-1900 England, Harington had to shear off his lustrous mane and scruff. Don’t worry though, guys! It’s just acting! Jon Snow will grow his hair back out in time for winter.
