The son of American stage and film actor George Marion, George Marion Jr. inaugurated his own show-business career writing subtitles for the 1925 Rudolph Valentino vehicle The Eagle. Moving to Paramount in 1926, Marion composed brief, witty titles for the films of Bebe Daniels, Clara Bow and other favorites. In 1929, he earned an Academy Award nomination for his titling efforts on 1927's Oh, Kay! Making a seamless transition to talkies, he wrote dialogue for such Paramount features as The Mysterious Dr. Fu Manchu (1929) and Love Me Tonight (1932). Later on, he moved to Paramount's next-door neighbor RKO, co-scripting films like The Gay Divorcee (1934) and Too Many Girls (1940). In addition to his screenwriting accomplishments, George Marion Jr. wrote song lyrics for a brace of 1930 films, Let's Go Native and Safety in Numbers.
