The Warning

Powerful and sometimes disturbing account of Britain's defences against enemy attack - made six months before WWII.

Documentary 1939 33 mins

Overview

This convincing, sometimes alarming account of Britain's response to enemy air attacks is all the more striking for being made some six months before war broke out. The film was intended to encourage Britons to think about Air Raid Precautions (ARP), using a well-prepared Nottingham to demonstrate effective civil defence under fire. But what lingers most is the vivid imagery of devastation, particularly a chilling sequence showing the aftermath of a gas attack.

The film ends with a sober appeal from Sir John Anderson, soon to be Home Secretary (his name would be immortalised in the 'Anderson shelters' dug into back gardens across Britain): "Your country calls upon you for your own protection and the protection of your families and your friends." The Warning was made not by the 'official' documentarists of the GPO Film Unit, but by British National Films, known for modest-budget features. Editor R.Q. McNaughton, though, had genuine documentary pedigree, with credits on Night Mail (1937) among others. Just after war broke out he cut The First Days for the GPO, which makes a fascinating counterpoint to The Warning.
