Marceline Day was born on April 24, 1908.
She began her film career after her sister Alice became a Sennett Bathing Beauty in the one and two-reel Keystone comedies. In 1926, Day was named one of the thirteen WAMPAS Baby Stars, a promotional campaign sponsored by the Western Association of Motion Picture Advertisers in the United States, which honoured thirteen young women each year who they believed to be on the threshold of movie stardom. She is probably best remembered for her role in the now lost 1927 horror classic, London After Midnight, directed by Tod Browning. Day played opposite Lon Chaney Sr and Conrad Nagel.
Marceline Day died on the 16th of February, 2000, aged 91.
