It’s truly thrilling to see the Barbican embracing big concept long-form theatre again, seeking out productions that are as conceptually challenging as they are visually exhilarating. Last week, audiences were asked to understand the forces of globalisation that shaped a royal wedding dress in the Théâtre National de Strasbourg’s multimedia tour de force, Lacrima.

In 1988, James Birch – curator, art dealer, and gallery owner – took Francis Bacon to Moscow. It was, as he writes, "an unimaginable intrusion of Western Culture into the heart of the Soviet system". At a time of powerful political tension and suspicion, but also optimism and opportunity, the process of exhibiting Bacon was riddled with difficulties, careful negotiations, joys and disappointments.

It’s no surprise that the theme of fakes and forgery appeals so much to writers, who traffic in plausible illusions and often believe (in María Gainza’s words) that truth is “just another well-told story”. From the age of Balzac and Zola to modern iterations in the novels of authors such as Michael Frayn, Donna Tartt and Maylis de Kerangal (in her recent Painting Time), shelves of fiction have drawn their plots around the fine pencil line that divides authenticity from imposture in art.

It’s been described as “the most improbable story that has ever happened in the art market”, and The Lost Leonardo reveals every twist and turn of this extraordinary tale. In New Orleans in 2005, a badly-damaged painting (pictured below left) sold at auction for $1,175.

There just isn’t enough there, with ANNA X. Daniel Raggett’s production is the third and final of the RE:EMERGE season at the Harold Pinter Theatre, with Emma Corrin of Lady Di fame in the lead. The graphic design – the brightly-striped faces of Corrin and her co-star, Nabhaan Rizwan, on a dark background – is impeccable. Joseph Charlton’s writing, not so much.

The limitations of life on screen are all too apparent at the moment, and yet still there are instances where online can offer something beyond the reach of an old-fashioned trip to an art gallery. Ultra-high resolution reproductions of works of art are a case in point, and many museum websites now allow us to examine their collections in the microscopic detail once reserved for conservation departments.

Arguably one of the most poignant effects of the lockdown has been to simultaneously draw attention to the connections between the arts and the distinct ways they have evolved into their own forms.

Of all the ventures that super-fraudster Anna Delvey might have chosen as bait for her victims, an exclusive art club was surely a masterstroke.

This brilliantly conceived and executed show is about provenance in art. It’s also about our perceptions of the truth. However, it’s a show where it would be churlish to reveal too much of what goes on.

Sitting somewhere between Ruben Östlund’s The Square and Final Destination, Dan Gilroy’s Velvet Buzzsaw is a satirical supernatural thriller that goes for the jugular of the LA art scene.
