I'm surprised this hasn't come out already . Paramount recently released 2 other films (Come Back Little Sheba and The Rose Tattoo ) which paired Burt Lancaster (at the time, a huge star) with a female lead in a theatrical adaptation. Paramount probably figured that Lancaster had enough star power to bring audiences to these films, since the female leads were either unknown to film audiences (Shirley Booth), foreign ( Anna Magnani), or slightly faded as stars at the time (Katherine Hepburn).
