Men in War is a 1957 war film about the Korean War directed by Anthony Mann and starring Robert Ryan and Aldo Ray as the leaders of a small detachment of American soldiers cut off and desperately trying to rejoin their division. The events of the film take place on one day; 6 September 1950. The picture was based on a 1949 World War II novel of the Normandy campaign Day Without End by Van Van Praag that was retitled Combat in 1951. Most of the same cast and crew made God's Little Acre the following year.
