Russell Crowe, who has played more than his fair share of rugged action heroes, makes his directorial debut with The Water Diviner, a film in which he plays, you’ve guessed it, a rugged action hero. He is Joshua Connor, a farmer living in the Australian Outback in the early 1900s, who has an uncanny knack of finding water sources, enabling him to farm this otherwise arid landscape (beautifully shot by Andrew Lesnie).

If proof were needed that war exists in some quarters as an excuse for beautiful images, along comes this screen account of Vera Brittain's celebrated 1933 memoir Testament of Youth to offer up prettified pain in abundance alongside some fine performances that do what they can to break through the prevailing gloss. First-time feature director James Kent's film can be seen as the converse to something like, say, the awful Unbroken, which rubs our noses almost fetishistically in suffering and torture.

Walter Summers (1892-1973), formerly Lt. Summers of the East Surreys and a highly decorated veteran of the Western Front, had already directed the Great War reconstruction films Ypres (1925) and Mons (1926) for Harry Bruce Woolf’s British Instructional Films when he embarked on BIF’s docudrama The Battles of Coronel and Falkland Islands (1927). This silent but thunderous war film, galvanized by Simon Dobson’s tense new score, is remarkable for its impartiality.

This huge exhibition is an awesome and terrifying compilation of photographs of the sites of conflict, and the remnants of wars and conflicts of all kinds – local, civil, short, long, global, technological, industrial and hand-to-hand. Taken from the mid 19^th century to the present, the images – hundreds, perhaps even well over a thousand –  are oblique and often incomprehensible or unidentifiable without the expansive wall captions. This is a show requiring us to read as well as look. 

This time of remembrance has inspired a fascinating theatrical skirmish. In one corner, Nicholas Wright’s 2014 Regeneration, an adaptation of Pat Barker’s trilogy; in the other, Stephen MacDonald’s 1982 two-hander Not About Heroes. Both plays, currently touring, concern the pivotal meeting of Wilfred Owen and Siegfried Sassoon at Edinburgh’s Craiglockhart War Hospital in 1917, but while the former examines shell shock and its treatment in compelling detail, the latter is content to place the poets and their enduring creations centre stage.

We seem to have spent most of 2014 examining the social, political, historical, geographical and military ramifications of the First World War. You would have thought, therefore, that the upcoming Remembrance Sunday commemorations could have been allowed to stand alone, uncluttered by further efforts to explain or dramatise the events of 1914.

Julian Fellowes, now the Conservative peer Lord Fellowes, left behind the fictional world of Gosford Park and Downton Abbey to give us this sumptuous tour of Blenheim Palace. Nor were its surroundings neglected as vista after vista showed us Blenheim’s lavishly landscaped gardens, fountains and columned monument to John Churchill, ^1st Duke of Marlborough, victorious over Louis XIV. It was his military prowess that led to wealth and Blenheim itself, gifted by the grateful nation and thus an early example of government subsidy.

As we arrive at the last few months of 2014, the temptation to say “Enough! No more!” to representations of the First World War creeps in. The centenary of 1914 has been so comprehensively commemorated on our stages and screens that you could be forgiven for feeling as if you had little left to understand about what went on. But don’t put it all behind you quite yet – this rediscovery from the 1930s still has something to offer in an overcrowded space.

At the end of this absorbing documentary about the art – and life – of Paul Nash we visited his tombstone in a Buckinghamshire churchyard, accompanying writer and presenter Andrew Graham-Dixon as he laid sunflowers on the grave. He reminded us that Nash saw the sunflower as a symbol for the soul, turning to the sun; indeed one of his last paintings was “Solstice of the Sunflower”.

This year the nation has been spirited back to 1914. Every aspect of the First World War has been explored - its causes debated, the horrific conditions on the front revisited. And yet there has been less talk of the psychological impact of trench warfare, which is why Nicholas Wright’s new stage adaptation of Regeneration will greatly add to the sum of the centenary coverage. Pat Barker’s novel was published in 1993 - and filmed in 1997 starring Jonathan Pryce - but more than 20 years on there is still no shrewder or more moving account of shellshock.
