After more than 20 years performing on stage, Walters expanded her career into films. A few of her early screen appearances from 1918 and 1919 are the six-reel melodrama "The Woman Who Gave", which was filmed in New York in the Adirondack Mountains; "The Zero Hour"; "Little Miss Hoover"; "Through the Toils"; and the comedy "The Misleading Widow". In its review of "The Woman Who Gave" in November 1918, "Variety" gives the film a positive assessment and highlights Walters' performance. "Dorothy Walters", the paper reports, "as Delia Picard, a matronly housekeeper, supplied the comedy and received a number of laughs."
