Question: Greta Garbo starred in a film with an American film actor often referred to as what?
Context: The Kiss is a 1929 American silent drama film from Metro-Goldwyn-Mayer directed by Jacques Feyder and starring Greta Garbo, Conrad Nagel and Lew Ayres in his first feature film.  The film is known for being both MGM's and Greta Garbo's last silent film.  It was also the last such film for Conrad Nagel.  That said, the film did take advantage of the new sound technology, and was released with an orchestral score and sound effects.  It was based on an 1896 film. Two-Faced Woman is a 1941 American romantic comedy film from Metro-Goldwyn-Mayer, directed by George Cukor and starring Greta Garbo in her final film role, Melvyn Douglas, and Constance Bennett.  Garbo plays a wife who pretends to be her own fictitious twin sister in order to recapture the affections of her estranged husband (Douglas), who has left her for a former girlfriend (Bennett).  The film is generally regarded as a box-office bomb and an unsuccessful attempt to "Americanize" Garbo in order to increase her United States fan base.  By mutual agreement, Garbo's contract with MGM was terminated shortly after "Two-Faced Woman" was released, and it became her last film. Susan Lenox (Her Fall and Rise) is a 1931 American Pre-Code film starring Greta Garbo and Clark Gable, based on the novel by David Graham Phillips.  The film was made by Metro-Goldwyn-Mayer and was directed and produced by Robert Z. Leonard.  This was the only film in which Greta Garbo was paired with Clark Gable.  The notoriety of the novel alone was enough for British censors to ban it from release.  With a few cuts, it was finally approved in the UK with a new title: "The Rise of Helga". Roy D'Arcy (February 10, 1894 – November 15, 1969) was an American film actor of the silent film and early sound period of the 1930s noted for his portrayal of flamboyant villains.  He appeared in 50 different films between 1925 and 1939, such as "The Temptress" in 1926 with actresses such as Greta Garbo. Mata Hari is a 1931 American Pre-Code Metro-Goldwyn-Mayer film loosely based on the life of Mata Hari, an exotic dancer and courtesan executed for espionage during World War I.  The film stars Greta Garbo in the title role.  It was Garbo's most commercially successful vehicle.  Only a censored version of the film is currently available. William Clark Gable (February 1, 1901 – November 16, 1960) was an American film actor and military officer, often referred to as "The King of Hollywood" or just simply as "The King".  Gable began his career as a stage actor and appeared as an extra in silent films between 1924 and 1926, and progressed to supporting roles with a few films for Metro-Goldwyn-Mayer in 1931.  The next year, he landed his first leading Hollywood role and over the next three decades he became a leading man in more than 60 motion pictures. Ninotchka is a 1939 American film made for Metro-Goldwyn-Mayer by producer and director Ernst Lubitsch which stars Greta Garbo and Melvyn Douglas.  It is written by Billy Wilder, Charles Brackett, and Walter Reisch, based on a screen story by Melchior Lengyel.  "Ninotchka" is Greta Garbo's first full comedy, and her penultimate film.  It is one of the first American movies which, under the cover of a satirical, light romance, depicted the Soviet Union under Joseph Stalin as being rigid and gray, in this instance comparing it with the free and sunny Parisian society of pre-war years. Greta Garbo (born Greta Lovisa Gustafsson; ] ; 18 September 1905 – 15 April 1990), was a Swedish-born American film actress during the 1920s and 1930s.  Garbo was nominated three times for the Academy Award for Best Actress and received an Academy Honorary Award in 1954 for her "luminous and unforgettable screen performances."  In 1999, the American Film Institute ranked Garbo fifth on their list of the greatest female stars of classic Hollywood cinema, after Katharine Hepburn, Bette Davis, Audrey Hepburn, and Ingrid Bergman. George F. Marion Sr. ((1860--) 16, 1860 – (1945--) 30, 1945 ) was an American stage actor and director, a film actor and director of two silent films.  George F. Marion, who was born in San Francisco, California was father of writer George Marion Jr. and he died of a heart attack at the age of 85 years in Carmel, California, United States.  Marion acted in 35 films between years 1915 and 1935.  He is best remembered for playing the father Chris Christopherson to the Broadway production of "Anna Christie" of Pauline Lord (1921 Broadway) and the two film versions of "Anna Christie" of Blanche Sweet (1923 silent) and Greta Garbo (1930 talkie).  His son George Marion, Jr. was a famous Hollywood screenwriter. Nils Anton Alfhild Asther (17 January 1897 – 19 October 1981) was a Swedish actor active in Hollywood from 1926 to the mid-1950s, known for his beautiful face and often called "the male Greta Garbo".  Between 1916 and 1963 he appeared in over 70 feature films, 16 of which were produced in the silent era.  He didn't seek publicity, choosing instead to be alone.  He is mainly remembered today for two silent films he made with his fellow Swede, Greta Garbo, and the pre-code interracial love affair in "The Bitter Tea of General Yen".
