Vera Zorina, born Eva Brigitta Hartwig, was a Norwegian ballerina, theatre and film actress, and choreographer. Today, she is chiefly remembered for her films choreographed by her then-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.

George Balanchine was an Georgian-American ballet choreographer, recognized as one of the most influential choreographers of the 20th-century. Styled as the father of American ballet, he co-founded the New York City Ballet and remained its artistic director for more than 35 years. His choreography is characterized by plotless ballets with minimal costume and décor, performed to classical and neoclassical music.
