Andrea King appeared in Broadway plays and other theater work before appearing in The March of Time's first feature-length film entitled The Ramparts We Watch (1940). In 1944, she signed with Warner Bros. and changed her stage name to King (some of her early movies have her credited as Georgette McKee - her stepfather's name). King appeared uncredited in the Bette Davis film, Mr. Skeffington (1944) and went on to do another ten movies in the next three years. King was originally cast to play Dr. Lilith Ritter in Edmund Goulding's film noir classic Nightmare Alley, but she choose instead a memorable role as sophisticated Marjorie Lundeen in Ride the Pink Horse (1947).
