Anna Karenina is an opera in two acts by American composer David Carlson, based on the 1877 novel "Anna Karenina" by Leo Tolstoy, commissioned by Florida Grand Opera to celebrate the 2007 opening of the Ziff Ballet Opera House at the Adrienne Arsht Center for the Performing Arts, co-commissioned by Opera Theatre of Saint Louis. The libretto is by British director Colin Graham, originally contemplated for Benjamin Britten's opera commissioned by the Bolshoi Theatre (the project was cancelled by the British after the Warsaw Pact invasion of Czechoslovakia). Graham was to have directed the original production; after his death only weeks before the opera's opening night, the direction was taken over by Mark Streshinsky. The opera is in two acts with a prologue and an epilogue, lasting just over two hours.
