Cryptocurrency is like the myth of El Dorado – a promised land made of fool’s gold. Despite its liberatory potential, it frequently attracts sharks or, as the title of Beru Tessema’s new play indicates, hungry wolves that gobble up defenceless sheep.

Mac is in prison for a long stretch. He is calm, contemplative almost, understands how to do his time and has only one rule – nobody, cellmate or guard, can touch the photo of his daughter, then three years old, attached to his wall. Though he is a man who gets through the days with few problems, he solves them through violence. On his release, his only wish is to find the daughter who will have forgotten him. 

Can experimental theatre survive the decades? This year marks the 40th anniversary of the Forced Entertainment theatre company, whose mission is summarised (by themselves) as “tearing up the rulebook”.

The Catalan capital has given its name to a famous number in the Stephen Sondheim musical, Company. And here it is lending geographical specificity to the second two-hander, following the far-superior Camp Siegfried, from American writer Bess Wohl to reach London in recent years.

It’s 1648 in Agra, and an excitable young guardsman has come up with an idea: a giant flying platform that he calls an “aeroplat”. As he might slide off it in transit, for good measure he gives it a belt to tie him down. It would be a “seat belt”, he suggests triumphantly.

Hanif Kureishi’s 1990 novel The Buddha of Suburbia begins like this: “My name is Karim Amir, and I am an Englishman born and bred, almost”. Almost. Yes, that's good. We are in 1970s south-east London, and this immediately introduces, despite its tentative tone, the protagonist as a young man trying to define his identity.

It is unsurprising to learn in the post-show Q&A that each audience receives Jonathan Maitland’s new play based on his 2006 memoir differently. My house laughed a lot (me especially) but some see the tragic overwhelming the comic, and the laughs dry up. When it comes to humour, as is the case with mothers, it’s each to their own.

Even by Stanley Kubrick’s standards, Dr Strangelove went through an extraordinary evolutionary process. After starting it off as a serious film about nuclear war based on the 1958 novel Two Hours to Doom, he decided to turn it into a comedy with the help of porn-obsessed satirist Terry Southern.

“Don’t take a piss in the house of a woman you have made a widow.” The mixture of earthy comedy and tragic pain in this piece of parental advice is typical of the tone of Richard Bean’s Reykjavik, his new work play which explores the lives of the Hull trawlermen of the mid-1970s.

The misadventures and misbehaviours of the English upper-middle class is catnip for TV executives. All those posh types on which us hoi polloi can sit in delicious self-righteous judgement, as we marvel at their cut glass accents, well-tailored clothes and ostentatious wealth. Meanwhile their worlds are always collapsing due to villainy, venality or misconceived virtue. Lovely stuff!
