[6] Shanor appeared in several silent films, notably in vamp roles[7] in serials, including The House of Hate (1918), The Queen of Hearts (1918), The Echo of Youth (1919), The Lurking Peril (1919), The Mystery Mind (1920), The Man Who Stole the Moon (1921), and The Prodigal Judge (1922).

[8] "Peggy Shanor distinguished herself, in The House of Hate, by her ability to go upstairs in a truly regal manner," noted one film magazine of her day.

[10] Shanor commented on her typecasting as a "vamp" in a 1920 interview: "I don't know why the public persists in calling any woman character in a play or picture who has red blood, brains or allurement a 'vamp'.

[16] Shanor was one of the entertainers donating their talents at a "smoke fund" benefit in New York in 1918, raising money to send cigarettes to American troops in World War I.

[18] In 1922 she was in the news for her role in a "hospital mystery", as fellow film actor Earle Foxe collapsed in her apartment at the Knickerbocker Hotel.
