Synopsis

Oh! What a Lovely War summarises and comments on the events of World War I using popular songs of the time, many of which were parodies of older popular songs, and using allegorical settings such as Brighton's West Pier to criticise the manner in which the eventual victory was won.

The diplomatic maneuvering and events involving those in authority are set in a fantasy location inside the pierhead pavilion, far from the trenches. In the opening scene, various foreign ministers, generals and heads of state walk over a huge map of Europe, reciting actual words spoken by these figures at the time. An unnamed photographer takes a picture of Europe's rulers – after handing two red poppies to the Archduke Ferdinand and his wife, the Duchess of Hohenberg, he takes their picture, "assassinating" them as the flash goes off. Many of the heads of state enjoy good personal relations and are reluctant to go to war: a tearful Emperor Franz Josef declares war on Serbia after being deceived by his Foreign Minister, and Tsar Nicholas II and Kaiser Wilhelm II are shown as unable to overrule their countries' military mobilisation schedules. The German invasion of Belgium leaves Sir Edward Grey little choice but to get involved. Italy reneges on its alliance with the Central Powers (it joined the Allies in 1915) but Turkey joins them instead.

The start of the war in 1914 is shown as a parade of optimism. The protagonists are an archetypal British family of the time, the Smiths, who are shown entering Brighton's West Pier, with General Haig selling tickets – the film later follows the young Smith men through their experiences in the trenches. A military band rouses holidaymakers from the beach to rally round and follow – some even literally boarding a bandwagon. The first Battle of Mons is similarly cheerfully depicted yet more realistic in portrayal. Both scenes are flooded in pleasant sunshine.

When the casualties start to mount, a theatre audience is rallied by singing "Are We Downhearted? No!" A chorus line dressed in frilled yellow dresses, recruits a volunteer army with "We don't want to lose you, but we think you ought to go". A music hall star (Maggie Smith) then enters a lone spotlight, and lures the still doubtful young men in the audience into "taking the King's Shilling" by singing about how every day she "walks out" with different men in uniform, and that "On Saturday I'm willing, if you'll only take the shilling, to make a man of any one of you." The young men take to the stage and are quickly moved offstage and into military life, and the initially alluring music hall singer is depicted on close-up as a coarse, over-made-up harridan.

The red poppy crops up again as a symbol of impending death, often being handed to a soldier about to be sent to die. These scenes are juxtaposed with the pavilion, now housing the top military brass. There is a scoreboard (a dominant motif in the original theatre production) showing the loss of life and "yards gained".

Outside, Sylvia Pankhurst (Vanessa Redgrave) is shown addressing a hostile crowd on the futility of war, upbraiding them for believing everything they read in the newspapers. She is met with catcalls and jeered from her podium.
