About Vera Zorina
Eva Brigitta Hartwig, known professionally as Vera Zorina, was a German-Norwegian ballerina, theatre and film actress, and choreographer, chiefly remembered for her films choreographed by her husband George Balanchine. They include the Slaughter on Tenth Avenue sequence from On Your Toes, The Goldwyn Follies, I Was an Adventuress with Erich Von Stroheim and Peter Lorre, Louisiana Purchase with Bob Hope, and dancing to "That Old Black Magic" in Paramount Pictures' Star Spangled Rhythm. A performance at London's Gaiety Theatre won her an invitation to join the Ballet Russe de Monte Carlo in 1933, at which time she adopted the stage name of Vera Zorina. Starting in 1948, Zorina appeared in Arthur Honegger's Joan of Arc at the Stake, playing the title role in the first American performance with the New York Philharmonic under Charles Münch.
