Youth, written by Vera Brittain and published in 1933, tells of how the author postponed her studies to Oxford to serve as a nurse in the Great War, during which she lost her fiance and brother. After the war, she tried to resume her life but found herself part of a lost generation, returning to Oxford and becoming a feminist and a writer.

Vikander is portraying Brittain; Harington will play her fiance.

Harington next appears in Pompeii, which opens Feb. 21. The period disaster movie is directed by Paul W.S. Anderson and co-stars Emily Browning and Kiefer Sutherland. He also returns as Jon Snow in season four of HBO’s Game of Thrones, which premieres April 6.
