The film stars Robert Taylor, Deborah Kerr, Leo Genn, and Peter Ustinov, and features Patricia Laffan, Finlay Currie, Abraham Sofaer, Marina Berti, Buddy Baer, and Felix Aylmer. Anthony Mann worked on the film for four weeks as an uncredited second-unit director. Sergio Leone was an uncredited assistant director of Italian extras. Future Italian stars Sophia Loren and Bud Spencer appeared as uncredited extras. The film was nominated for eight Academy Awards (though it won none), and it was such a huge box office success that it was credited with single-handedly rescuing MGM from the brink of bankruptcy.
