Reach for Glory (1962)

During World War II, teenage boys in a small English town are consumed with jingoism and brutal war games, hoping dearly that the war won't end before they can fight in it. John, one of the younger members, is increasingly torn between these peer group values and his deepening homoerotic friendship with Mark, a gentle Jewish refugee whom his gang has ostracized as a sissy and a coward. Based on the novel "The Custard Boys", by John Rae. Reminiscent of "Lord of the Flies" in depicting adolescent cruelty growing unchecked to tragic extremes.
