The War Game is a fictional, worst-case-scenario docu-drama about nuclear war and its aftermath in and around a typical English city. Although it won an Oscar for Best Documentary, it is fiction. It was intended as an hour-long program to air on BBC 1, but it was deemed too intense and violent to broadcast. It went to theatrical distribution as a feature film instead. Low-budget and shot on location, it strives for and achieves convincing and unflinching realism.

Part interviews and quotations, part acting, this film simulates the aftermath of a large-scale nuclear attack near a rural area of England. It argues that citizens and Civil Defense authorities are poorly prepared for this eventuality, and describes possible physical, psychological and social damage in graphic detail.
