Eugenie Leontovich (Russian: Евге́ния Леонто́вич; March 21, 1900,Moscow, Tsarist Russia – April 3, 1993, New York City) was a Russian-born stage actress with a distinguished career in theatre, film and television. She was described as "[o]ne of the most colourful figures of the 20th-century theatre, a successful actress, producer, playwright and teacher."

Born in Moscow, although the year of her birth has been disputed, with some sources citing 1896, others 1900, she studied at that city's Imperial School of Dramatic Art, and then under Meyerhold at the Moscow Art Theatre, which she subsequently joined. As the daughter of an officer in the Russian Imperial Army, Leontovich suffered greatly during the Revolution. Her three brothers (who were Army officers like their father) were murdered by the Bolsheviks. In 1922, she "found her way to New York and set about mastering the English language". Her success in doing so led to Broadway stardom.

After touring the country in Blossom Time, she was cast as Grusinskaya in an adaptation of Vicki Baum's novel Grand Hotel. An enormous success, the play, which opened in 1930, was later filmed with Garbo in the part created by Leontovich. After Grand Hotel Leontovich was given the role of Lily Garland (aka Mildred Plotka) in Twentieth Century, a comedy by Ben Hecht and Charles MacArthur that was later made into a musical, a decided change of pace. She played the role from December 29, 1932 until May 20, 1933.

Gregory Ratoff (20 April 1897 — 14 December 1960) was a Russian-born American film director, actor and producer. His most famous role as an actor was as producer Max Fabian who feuds with star Margo Channing (Bette Davis) in All About Eve (1950).

Ratoff was born in Samara, Russia to a Jewish family. The actor first came to the United States in 1922. He married the Russian actress Eugenie Leontovich in 1923 (they divorced in 1949). He returned to the United States, passing through Ellis Island in July 1925. On the steerage passenger list of the SS Mauretania he was listed as Gregoire Ratoff; for next of kin he listed his mother, Mme. Sophie Ratner of Paris.

Ratoff is most noted for having directed the pro-Soviet propaganda film Song of Russia (1944) and for being one of the two producers to have purchased and developed the original rights to the James Bond franchise from Ian Fleming in 1955.

Ratoff died on 14 December 1960 from leukemia in Solothurn, Switzerland, aged 63. His body was returned to the United States for burial at Mount Hebron Cemetery in Flushing, New York. Although divorced from Leontovich, Ratoff was buried under a gravestone marked Beloved Husband.
