Far Away, Donmar Warehouse review - one for the devotees

Caryl Churchill, Britain's best living playwright, is enjoying a spate of high-profile revivals of her classic work. Last year, the National Theatre staged her Top Girls, and an upcoming production of A Number is coming soon to the Bridge Theatre.

In the meantime, Far Away, her visionary 2000 play about genocide and the war on terror, arrives at the Donmar Warehouse. Twenty years after its first outing at the Royal Court, when it was staged by Stephen Daldry (didn't he do well?), it is now directed by Lyndsey Turner, who in 2019 reinterpreted Top Girls as a big state-of-the-nation drama in a notably fluid and high-definition way. Can she cast a similarly fresh eye on this much more slender play?

Far Away is a very short play, yet it suggests a huge canvas of pain. Of its three brief scenes, the first is set in the kitchen of Harper, a middle-aged woman who lives in a remote house. Her young niece, Joan, has accidentally witnessed a horrible scene involving Harper's husband. The aunt tries to persuade her that she's imagining things. But we know better. The second scene is set in a workshop, more than a decade later, where Joan has begun work as a hat maker. She chats to Todd, who's been there for a number of years. Then it emerges that the hats are part of a extremely disturbing ritual. In the final scene, Harper and Todd are waiting for Joan at Harper's house, and their dialogue evokes a world war that is completely crazy.

The play is a good example of leftfield theatre, in which contemporary issues are depicted in a dazzlingly imaginative way. It's unrealistic, increasingly surreal, but also resonant. At various points, the story evokes the genocidal horrors of Nazi Germany and the Bosnian civil war of the Nineties and, which is even more remarkable, it seems to anticipate the total craziness of the 21st century global war on terror as well as recent anxieties about catastrophic climate change. Watching this revival, you can't help but think of the banality of evil. The story shows how ordinary people get sucked into witnessing, or accepting, really bad things. But, more hearteningly, it also shows that resistance is possible. Yet, at the same time, that it might be totally, and depressingly, futile.

I do love this play, but I must admit that – unlike Churchill's very best work – its meaning doesn't deepen very much over the decades. Okay, you could argue that, in the era of Trump, it feels even more like a prediction of the future than a vision of a dystopic nightmare. But the nature of visions is that they either come literally true, or they remain visionary. And this one remains what it always was: a beautifully imagined fantastical nightmare. In the year of Brexit, the brief mention of France as the "enemy" gains some strength, and the similarly casual mention of China likewise feels contemporary. But more striking still are the surreal passages describing the evil of crocodiles and the threats, not of international capitalism, but of international dentistry. Yes, it is also gently amusing.

But if the content of the play is an escalation of the bizarre, the patterns of thought of the handful of characters are disturbingly familiar. The bigotry, twisted reasoning and blindness to horror are all too human. In times of stress, blame the traitors. Suspect everyone. As Joan, Harper and Todd react to life first in a regime, witnessing the increasing cascade of violence, and systematic murder, and then take up arms to resist it, their political awareness grows. As this happens, their arguments get more bitter and more painful. So recognisably human. Amid the imaginative playwriting there's a strong pull of emotional realism. In the end, we are witnesses of the trauma of atrocity.

Turner's production is attractively designed by Lizzie Clachan, whose background and floor is red baize, and their staging of the crucial parade scene, with its noisy Viennese waltz music, is vivid in its cruel mockery of humanity. Blinding flashes of light cover the fluid scene changes, and the detail of the production is well observed. In the opening scene, for example, Young Joan – played on press night by Sophia Ally (a role shared with Abbiegail Mills) – has dirty feet because she has climbed outside on a tree; Harper works on a rug that has a nostalgically bucolic picture on it. In between scenes, Young Joan is shown peering into a lorry, carrying a work box or transporting a Kalashnikov.

The cast deliver thoughtful performances: Jessica Hynes, BAFTA winner familiar from W1A and Years and Years, gives a convincing account of the evasive Harper when she is confronted by the beautifully observed naïve curiosity of Young Joan (pictured above), although her touch is less sure in the final avalanche of surrealism. As the adult Joan, Aisling Loftus is touching as the newcomer to the workshop, growing into the tense and troubled freedom fighter opposite Simon Manyonda, who brings to the part of Todd a sincere and grounded common sense. But while Churchillian devotees will admire the cool economy of the writing and the emotional truth of the acting, other theatre-goers might wonder why they should take the trouble to see a show that barely lasts 40 minutes.
