Slender, sad-eyed leading lady Rosemary Theby made her film debut in 1912, and that same year starred as Celia in a greatly abbreviated film version of Shakespeare's As You Like It. In her heyday (1915-1922), Theby often co-starred with her husband, actor/director Harry C. Meyers; among other roles, she played Morgan Le Fey in Meyers' lavish version of A Connecticut Yankee in King Arthur's Court (1921). Professional and financial reverses forced both Theby and her husband into bit parts and extra roles during the talkie era. Several of Theby's 1930s assignments were obtained through the kindness of comedian Oliver Hardy, who'd been a minor player in some of the actress' pre-WWI vehicles. Rosemary Theby's best talkie role was the laconic Mrs. Snavely in the classic W.C. Fields two-reeler The Fatal Glass of Beer (1932).
