Imaginative plays that explore the expanses of inner space are all the rage at the Soho Theatre this summer. First there was a superb revival of Anthony Neilson’s Realism, which puts on stage the thoughts of one man during a solitary Saturday, then there was Lou Ramsden’s Hundreds and Thousands, which used a horror-film aesthetic to explore female longing. Now Mongrel Island, which opened last night, looks at the thoughts and emotions of one woman who has a boring office job.

Can journalists write good plays? Sarah Helm has been a Washington correspondent for The Independent during the first Gulf War in 1990, reported from Baghdad in the mid-1990s, and was based in Jerusalem for three years. So her debut play about the Iraq War, which stars Maxine Peake and opened last night, is grounded on a career of watching the Middle East.

Situation comedy relies on strong brands, and some ideas just run and run. Yes, Prime Minister is the stage version of the long-running 1980s BBC television shows Yes Minister and Yes, Prime Minister, which memorably starred Nigel Hawthorne and Paul Eddington. First seen at Chichester last year, the play now returns, with a new cast, for a second West End season. But how does this trusty old brand stand up to the stresses and strains of current political life?

John Gay’s 1728 satirical drama was the first ballad opera. The vernacular work not only cocked a snook at the Italian operas that were so in vogue in 18th-century London, but it also lampooned Whig politician Sir Robert Walpole and the British love for scoundrels. It was an instant, huge hit; as a witticism of the time had it, The Beggar’s Opera made Rich gay, and Gay rich.

They say that moving home is always traumatic. So the Bush Theatre in west London must be feeling a wee bit fragile because it has recently upped sticks and taken up residence in the Old Shepherds Bush Library building just around the corner from its historic but rather leaky former home. Yet it’s typical of this spunky venue that it celebrates the first stages of the move with not only a trilogy of short plays, but also with an invitation to the audience to comment on its new space.

It's not often in classic comedy that you cry with laughter at the opening gags, and even rarer that the final scene of perfectly orchestrated ensemble acting actually crowns the work. More than two decades on from his groundbreaking Old Vic production of Ostrovsky's Too Clever By Half, director of genius Richard Jones is still finding the right mugs and pushing the boundaries of edgy satire.

Some theatre genres seem indestructible. One of these is the satirical city comedy, for which playwrights dip their pens in poison and spray their venom over the teeming mass of the shallow, the stupid and the successful. When they do this today, they inevitably recall all manner of past plays from Jacobean and Restoration times to Richard Brinsley Sheridan’s The School for Scandal, and beyond. In American Trade, a new play from the immensely talented American playwright Tarell Alvin McCraney, which opened last night, we revisit this familiar territory.

"There’s no possibility of being witty without a little ill-nature,” preaches the Gospel according to Richard Brinsley Sheridan. What the playwright omits to mention, however, is that it is possible to be ill-natured without in fact being terribly witty, a flaw that proves almost fatal for Warner’s acerbic, alienated new production of The School for Scandal. Overstyling Sheridan’s most stylised of comedies, Warner turns what Hazlitt described as the most “finished and faultless” play into a mass of tensions, exaggerations and contradictions. The result can be exhilarating in the moment, but wears off into confusion and a slight headache.

One of the great pleasures of being a critic is watching a career develop, and Stewart Lee’s is one that I’ve had the pleasure of, so to speak, for many years.

The Czech New Wave sprouted out of a fertile collaboration between film and fiction. Milan Kundera started out as a lecturer in film, lest we forget; one of his pupils was Miloš Forman. Both flew the communist nest to live and create abroad, which is why their names reverberate down the decades much more than those of the director Jiří Menzel and novelist Bohumil Hrabal, whose collaboration on Closely Watched Trains won the Oscar for Best Foreign Film in 1967.
