Problem:Article: Book now to see Keira Knightley and Elisabeth Moss star in The Children's Hour at the Comedy Theatre in London. Dates: 22 January 2011 to 31 January 2011 Times: 22 Jan 2011 6:30 PM; 24--29 Jan 2011 7:30 PM; 29 Jan 2011 2:30 PM; 31 Jan 2011 7:30 PM. Place: Comedy Theatre The Children's Hour The Children's Hour by Lillian Hellman is a striking play about the power of a lie. Karen Wright (Keira Knightley) and Martha Dobie (Elisabeth Moss) run a girls' boarding school in the 1930s New England. When an angry student starts a rumour that the two headmistresses are having a lesbian affair, it gradually destroys the women's careers, relationships and lives. The Children's Hour is an upsetting story of cheat, shame and courage. Banned in London and several cities across America, The Children's Hour received its world opening on Broadway in 1934. Generations on, its exploration of a culture of fear remains remarkably relevant. Keira Knightley and Elisabeth Moss Star Keira Knightley, nominee for Best Actress 2010 Evening Standard Awards for The Misanthrope, returns to the London stage. Knightley starred in Love Actually, The Pirates of the Caribbean Trilogy, Pride and Prejudice. Elisabeth Moss, best-known for playing Peggy Olson in Mad Men, made her Broadway stage debut in David Mamet's Speed the Plow in 2008. The Children's Hour will be her West End debut.
