Keira Knightley has joined Disney’s live-action Nutcracker movie, Variety reports, joining a cast that also includes Interstellar’s Mackenzie Foy, ballerina Misty Copeland, and Morgan Freeman. The Begin Again star will play the Sugar Plum Fairy, whose theme is one of the most recognizable melodies of Tchaikovsky’s 1892 ballet. Unlike the ballet, though, The Nutcracker and the Four Realms will only have one major dance sequence. Also unlike the ballet, Keira won’t have to play her role nightly.
