If it's possible to take a loving and empathic approach to decidedly intractable material, the director Michael Attenborough achieves precisely that with Filumena, in which Samantha Spiro follows on from (and surpasses) Judi Dench in author Eduardo De Filippo's title role of the one-time Neapolitan prostitute who in early middle age decides that what matters most is to be una mamma.

No one can exactly accuse Federico Garcia Lorca's 1936 play of falling into neglect. From Howard Davies's National Theatre revival to this latest reclamation by the Almeida, The House of Bernarda Alba has received six separate airings in (or near) London within almost seven years. The various treatments include an American stage musical, an adaptation relocated to Pakistan, and a puppet play performed to a pre-recorded Farsi soundtrack.

This needs confessing. Neil LaBute and I have an uneasy relationship. David Mamet - in Oleanna or Boston Marriage mode – also gets under my skin. It’s a close-run thing: misogyny exposed, or the thing itself? After Fat Pig (2004) and The Shape of Things (2005), Reasons to be Pretty is the third in LaBute's trilogy of plays about female appearance, and his seventh collaboration with the Almeida.

“Whose idea was it to do the gig in this shithole?” asks Captain Sensible towards the end of the night. He’s right. The East Wing is truly an atmosphere-free venue, a carpeted, low-ceilinged conference room that’s part of the much larger Brighton Centre complex. It’s easy to imagine it filled with municipal administrators milling about, the stink of coffee and the rustle of paperwork. Instead, it’s packed to the gills with men and women, mostly in their late forties and early fifties, mostly clad in black, lots of leather and badges.

Welcome back Stephen Poliakoff. With his first new play for 12 years, the master penman has set aside his television excursions into history and memory — most recently Glorious 39 for the BBC — for a haunting, contemporary tale of chance encounters and mysterious city nights. As the title makes clear, the play is a vision of London which is both personal and meditative. For me, it felt like a trip to a world that is surprising yet also familiar.

Whatever the quality of the material with which they're grappling, there are two undeniable truths about the Belarusian actors who've put their already curtailed freedom on the line by coming to the Almeida Festival this week: they're skilled practitioners of their art and courageous human beings. Read their biographies in the programme and you'll see that the words "detained", "arrested", "attacked", "dismissed" crop up rather a lot. In Europe's last dictatorship, stepping out on stage and speaking a line, a word even, can lead to imprisonment.

Serenity hangs by a fraying thread in the thrilling Almeida Theatre revival of A Delicate Balance, Edward Albee's 1966 Pulitzer Prize-winner about remembrance, fear, and somehow facing a new day. This particular playhouse has long been associated with Albee, from its (overrated) Who's Afraid of Virginia Woolf? through to various UK and even world premieres. But James Macdonald's production of the play that follows Virginia Woolf in the Albee canon stands a league apart, perhaps in sympathy with the work itself. The audience last night laughed plenty, sometimes (if truth be told) strangely, and yet by the end gave way to the voluble stillness that bespeaks a playgoing public stunned into silence.

In a play about drugs for a secondary-school audience there is always the potential for cringing. My own experience of theatre for a young audience involved PSHE lessons, overtly moral drama from hammy actors and dated street names for drugs. It was The Magic Roundabout, only more awkward and less entertaining. The Almeida Theatre and its solid Young Friends scheme is working hard to give youth theatre a better image through Crawling in the Dark, a new play which deals with young people and, yes, drugs, but without an embarrassing reference in sight.

A sliderule of 11-15 per cent reductions in annual grants by 2015, compared with this year, has been applied to Britain's major orchestras, opera, dance, theatre and music organisations. One major gainer is London's Barbican Centre - one major loser is the now world-famous Almeida Theatre, which loses almost 40 per cent of its current annual subsidy despite its reputation for innovation and discovery. However, the Arcola Theatre, another small innovative theatre, gets a big boost. Companies to lose all their grant from next year include Hammersmith's Riverside Studios and Derby Theatre.

The Knot of the Heart takes its title from a Sanskrit phrase, but David Eldridge's new play for the Almeida Theatre is likely to speak forcibly to anyone who has witnessed, not to mention experienced, the addiction unsparingly charted across two hefty acts. That the play may hit some too close to home was strongly evidenced on press night by responses ranging from audible sobs to walk-outs and a woman who fainted early on.
