According to their mother, Luda (played by Madeleine Worrall, pictured below), each of the three sisters (pictured top) in Napoli, Brooklyn, bears one of their father’s admirable traits. Tina (Mona Goodwin), the oldest, who left school early to earn money for the family in a factory job, has his strength. Vita (Georgia May Foote), who is smart but has been banished to a convent school for crossing her father, has his tongue.

What could have been merely a cheap and cheesy piss-take registers as considerably more robust in The Last Temptation of Boris Johnson, journo-turned-playwright Jonathan Maitland's latest venture for his de facto home at north London's Park Theatre.

Theatrical alchemy is eternally slippery.

Adultery seldom looks less adult than in the form of the mild-life crisis – that much-satirised condition in which desire is eclipsed by delusion, wisdom by foolishness, and sensible coats by leather jackets.

Les Dennis was once a marquee name on Saturday night television as host of Family Fortunes, but since giving up the light entertainment lark he now plies his trade as an actor, and a very good one at that. If you've not seen it, give yourself a treat and watch his bang-on-the-nose performance as “Les Dennis”, a delusional, whinging has-been, in Ricky Gervais and Stephen Merchant's Extras.

Britain is rightly proud of its record on multiculturalism, but whenever cross-cultural couples are shown on film, television or the stage they are always represented as a problem. Not just as a normal way of life, but as something that is going wrong. I suppose that this is a valuable corrective to patting ourselves on the back about how tolerant a society we are, but do such correctives make a good play?

Forget about dark alleys, deserted parks and slippery slopes: the most dangerous place in the world is likely to be your family. That’s where the traps are, the minefields and the surprise betrayals. As its title suggests, Torben Betts’s new comedy is all about failing marriages and imploding families.

Writer Robert Schenkkan’s Building the Wall imagines modern America in the not-too-distant future. The date is 22nd November 2019 and following an attack on Times Square in which 17 people were killed, martial law has been imposed. Demands for illegal immigrants to be thrown out of the country have resulted in mass round ups and swollen detention centres. Hysteria stalks the country.

There are few things more British than talking about the weather. What makes this play about a meteorologist interesting, however, is its historical setting: the eve of D-Day, the Allied invasion of Nazi-occupied Europe.

Is Buddhism a path to finding spiritual enlightenment – or just an excuse for not facing your personal problems? Given that this question is implicit in the debut play by Sam Bain, script co-writer of nine series of Channel 4’s Peep Show, as well as having other credits on Fresh Meat, Babylon and Four Lions, you’d expect the answer to be the latter. And you wouldn’t be wrong.
