Irwin's buxom figure was much in vogue at the time and, combined with her charming personality, made her one of America's most beloved performers for more than thirty years. In 1914, she made her second silent film appearance, this time in the feature-length adaptation of George V. Hobart's play, "Mrs. Black is Back", produced by Adolph Zukor's Famous Players Film Company and filmed for the most part at her own sprawling home in New York. Still pictures showing May survive from this movie.
