After considerable experience on the New York stage, Morgan Wallace entered films at D.W. Griffith's studio in Mamaroneck, Long Island. Wallace's first screen role of note was the lecherous Marquis de Praille in Griffith's Orphans of the Storm (1921). Thereafter, he specialized in dignified character parts such as James Monroe in George Arliss' Alexander Hamilton (1931). A favorite of comedian W.C. Fields (perhaps because he was born in Lompoc, CA, one of Fields' favorite comic targets), Wallace showed up as Jasper Fitchmuller, the customer who wants kumquats and wants them now, in Fields' It's a Gift (1934). Morgan Wallace retired in 1946.
