Georgia Backus (October 13, 1900; Columbus, Ohio – September 7, 1983; Sun City, California) was an American film actress who played mostly uncredited bit parts in more than 30 Hollywood films during the 1940s and early 1950s. She appeared in Orson Welles' Citizen Kane (1941) as Bertha Anderson and as a matron in The Magnificent Ambersons along with the 1942 hit film I Married a Witch. Her most widely noted role may have been as Mrs Warren, the helpful neighbour with a garden in the 1951 film noir Cause for Alarm!.[1]
