Rivalen (1958)

Kings Go Forth is a 1958 American black-and-white World War II film starring Frank Sinatra, Tony Curtis, and Natalie Wood. The screenplay was written by Merle Miller from the 1956 novel of the same name by Joe David Brown, and the film was directed by Delmer Daves. The plot involves friends of different backgrounds manning an observation post in Southern France who fall in love with the same French girl. She proves to be of American Mulatto ancestry. Themes of racism and miscegenation provide the conflict elements between the leading characters, something that was out of the ordinary for films of the time, while the setting during the so-called Champagne Campaign remains unique.
