Clarke, Mae; Curtis, James, ed. (1996). Featured Player: An Oral Autobiography of Mae Clarke. Lanham, MD: Scarecrow Press. p. 222. Clarke: "We divorced quickly because I added everything up and said, 'I've got to get out of this if I'm going to get on with responsibility for my own survival.' I couldn't carry him as a load, and he wasn't going to help me any. I had to go, and he didn't mind letting me go. By then, I guess I wasn't too pretty. And we hadn't even gotten to know each other. It was a fast marriage to begin with, an emotional thing at the time of the war." Curtis: "You got back into films in the spring of 1948." ISBN0-8108-3044-2.
