Elisabeth Moss will be making good use of her Mad Men winter break, having signed on to join the already-cast Keira Knightley in a West End stage revival of The Children’s Hour, reports Variety. Lillian Hellman’s 1931 play will pair the two actresses as headmistresses whose lives are destroyed when a pupil accuses the two of being lesbians. You will intuit that this is a period piece by the fact that the combination of the phrases “Keira Knightley,†“Elisabeth Moss,†and “lesbian lovers†results in despair and suicide instead of ultralucrative search-engine optimization. Maybe it really does get better! [Variety]
