 In the early 1960s, McCall and actress Joan Shawlee formed a team to perform as a night club act, debuting the act at the Club Robaire in Cleveland.In January 1961, syndicated newspaper columnist Dorothy Kilgallen reported that the team was "causing quite a stir", and she cited the partners' discrepancy in height — "Joan being six feet, three inches tall and Mitzi four feet, 10 inches short" — albeit exaggeratedly.In 2009, McCall had a supporting role as Bonnie in the film "World's Greatest Dad".
