James Dean's first movie role was far from cushy. This Korean War film was the first to depict the violence of combat. Director Samuel Fuller was given free reign to portray the grisly "kill or be killed" premise of the film, and he took it! Actors and camera crews were pushed to their physical limits, including lead actors Richard Basehart, Gene Evans, and Michael O'Shea. Twenty-year-old Dean was uncredited in the film and had only one line, which was cut in the final production.
