Few theatrical collaborations have been as successful as that achieved over five plays, two films, several decades, and numerous awards by the playwright Alan Bennett and the director Nicholas Hytner, who had jointly made a habit of art well before Bennett decided to write a play of that very name, premiered in November 2009 at the National Theatre. Now, More4 has come along with a documentary chronicling the two men's collaboration on a work that is itself about a collaboration. And if Adam Low's behind-the-scenes take on an essentially private meeting of minds leaves you wanting more, well, even some of Bennett and Hytner in action is better than no glimpse of them at all.

I'm not sure that Alan Bennett and The Habit of Art will prove all that revealing for those already interested in and admiring of a playwright who, intriguingly, tends to resist being put under the spotlight himself, even as his own plays offer often deeply intimate, sometimes scabrous views of people no longer around to answer back. (Those who saw The Habit of Art during its extended run on the South Bank and then on tour will have learned more than they could ever have anticipated about the poet W H Auden's sexual, um, habits.) How open was Bennett willing to be, then, about a process - writing - that is itself notoriously tricky to dramatise? Enough to satisfy up to a point. And yet it was left to Hytner briefly to play the analyst, making clear that the play's original title, A/B, referred not just to its putative subjects, Auden and the composer Benjamin Britten (pictured below), but, of course, to the initials of its author. (This script's intermediary title, Caliban's Day, reported previously, went unmentioned.)

Instead, we got footage of Bennett and Hytner reflecting both jointly, and individually, on the play's birth pangs, along with snippets of commentary from its enormously talented leading men, Alex Jennings (Britten) and Richard Griffiths (Auden), the latter of whom stepped in during rehearsals following the departure due to illness of original co-star Michael Gambon. (The full impact of Gambon's exit on the rest of the company was not explored.) This recent material was interspersed with a version of, presumably, much the same enquiry into Auden and Britten's own professional and personal dovetailing and eventual separation that Bennett must have engaged in himself, though Bennett's own preface to the published script of the play is, in fact, more complete on this front than the documentary manages to be.

That said, it was fascinating to be reminded of the extraordinary ravines of Auden's face and how aptly evocative they are of Gambon, next to whom the smooth-cheeked Griffiths was about as far-removed physically from the poet he was asked at the 11th hour to play as it was possible to be. (Hytner's finished stage production made a wry joke out of that very fact.) And one might have liked an even greater investigation into the process whereby an apparently straightforward bioplay morphed over successive drafts into a far more complex and moving look at the relationship between play and playwright as Bennett decided to encase his Auden/Britten face-off within a show that just happens to take place within the very rehearsal room that Bennett can by now call a second home - a play, in other words, first intended to lay bare the lives of others turned into a meditation in some way on its creator.

With musical scoring including Britten's always welcome Sea Interludes, Low's film hinted at a creative reckoning in Bennett that finds rough equivalents to Auden and Bennett in his play, images of Britten walking the Suffolk beach paralleled by shots of Jennings making his way down one or another backstage corridor at the National. I waited in vain for a recapitulation of that delicious final speech in Bennett's play in which Frances de la Tour's inimitable stage manager, Kay, spoke the author's title. But to see Bennett visibly worrying his latest creation at this point in a career spanning a half-century of kudos was to be reminded that the habit of art can be as hard as, with luck, it is glorious. Let's hope it's one habit Bennett doesn't kick any time soon.

Overleaf: more Alan Bennett

When the hit Broadway musical Fela! reached London last week, Femi Kuti joined the ovations on opening night with more feeling than most. The musical’s subject, his father Fela Kuti, was a government-taunting mix of James Brown and Che Guevara, a musical revolutionary who, with drummer Tony Allen, forged Afrobeat, and a polygamous, dope-smoking thorn in the side of successive corrupt Nigerian governments.

“It seems to me there’s nae end tae trouble. Nae end tae havin’ the heart torn out of you.” That’s the gut-wrenching cry of despair voiced by Maggie Morrison, the worn-down woman who is herself the heart of Ena Lamont Stewart’s vivid, sprawling 1947 drama. The piece was voted one of the 100 greatest plays of the 20th century in the National Theatre’s millennium poll; yet, aside from a landmark revival by Scottish company 7:84 back in 1982, it’s rarely been seen. Now young director Josie Rourke, who currently helms the Bush Theatre in west London, seizes upon the work for her South Bank debut. The results are nothing short of sensational.

As arts cuts announced today start to bite, few people are aware that the Royal Opera House pays its two top people more than £630,000 and nearly £400,000 each. Although Covent Garden is refusing to identify them, it is likely that they are chief executive Lord Hall and music director Antonio Pappano. But they are not likely to have to sacrifice their earnings even while smaller arts organisations fold.

The National Theatre’s new production of Hamlet is both a very good Hamlet, yet also a somehow disappointing one. For a work so rich in possibilities, with so much emotion, so much superb and intricate engineering, it is often like this, in England or anywhere else - inspiring and unconvincing at once.

Theatrical conceits, much like London buses, seem these days to come in threes. Or so it is suggested by the Neil Bartlett/Handspring collaboration Or You Could Kiss Me, the third Cottesloe production this year to peer into the future, albeit only as far as 2036, whereas Mike Bartlett's Earthquakes in London leapt forward to 2525. (Completing the trifecta: Tamsin Oglesby's Really Old, Like Forty Five, set a comparatively imminent 40 years ahead.) And while Oglesby's play featured a robotic nurse, this latest opening puts some very singular puppets centre-stage, alongside a vision of infirmity that could not be either more human - or humane.

In 1913 a 25-old-year mathematician from Tamil Nadu sailed to England. He journeyed at the behest of a Cambridge professor who had been mesmerised by the display of untutored genius evident in the young Indian’s correspondence. Within four years the visitor had grown so depressed by his isolation that he attempted to throw himself under a train.

The longest and most densely historical play by Georg Büchner (1813-37) is a potential monster. In German, Dantons Tod can run to four hours or more. There's little action and much speechifying. In plays by his equally wordy, history-obsessed predecessor, Friedrich von Schiller, there are at least fights, battles, a lot of love - and some sex.

Political playwright Howard Brenton (b. 1942) is always in the process of being "rediscovered". Yet at the same time he has been at the heart of British theatrical life for the past 40 years, since his debut in 1969 with Christie in Love. True, he has spent the odd decade out of the theatrical limelight - a few years ago, he "went out of fashion" in his own phrase – and then he just happened to pen some of the liveliest scripts on television with the BBC’s spy drama series, Spooks (2002-2005).

“Tragedy reminds us how to live,” declares Moira Buffini’s democratically elected heroine, Eurydice. It’s a reminder the playwright herself and her latest work, Welcome to Thebes, is eager to provide. Following on the well-worn heels of last season’s Mother Courage at the National comes a new play that once again places women in the front line. Leaving to Brecht the barren fields of Western Europe, Buffini sets up her stall in the fertile dramatic ground of contemporary Africa – a place where gang-rape and murder are just the prologue.
