Rungano Nyoni’s debut feature premiered at last year’s Directors' Fortnight in Cannes, and immediately marked the Lusaka-born, Wales-raised director down as a figure to watch. Putting her film into any category is more challenging, though, with its elements of fable and somewhat surreal satire, although “surreal” and any associated hints of the absurd risk saying more about the perspective of the observer than the world Nyoni herself depicts.

But however you look at it, I Am Not a Witch is a startling, vibrant piece of filmmaking. Over a spare 90 minutes Nyoni follows her nine-year-old heroine on an unlikely journey: rejected from one community because she stands out as an unlucky outsider, she is attached to a state-supported witch colony, then exploited as a curiosity and for commercial ends by her semi-official “minder”. The name she is given by the community of much older women into which she is partly absorbed is Shula, which tellingly means “uprooted”. She’s outstandingly played by Maggie Mulubwa, a tribal girl found by Nyoni, whose silence through most of the film leaves her face to speak, indelibly, about unspoken fear and apprehension and plaintive bafflement.There’s such sadness there: the few moments when Shula seems to be discovering something about herself, for herself, are so tentative that the film’s conclusion almost comes as a tragic relief. In parallel to the wider position of women in society, Nyoni has come up with an unnerving central image for her community of witches: they are tethered on long ribbons, attached to huge bobbins, that supposedly prevent them from flying away. Her opening scene shows a witch camp (the director spent time in one such place, in Ghana) being visited by tourists, a pitiful place where impassive old women sit around apathetically, their faces daubed in white.

At least when they are taken out to work – they travel on a special lorry, converted to accommodate their bobbins, a bizarre and unforgettable sight – there’s a certain sense of community, of personality, laced with unlikely, sometimes dark humour (the visit of a wig-seller peddling the latest models, mis-named after US pop celebrities is just one such moment). Gin is another consolation for them. Surrounding official structures, nominally perhaps benign but in practice indifferent, are resolutely male, embodied by the rotund Mr Banda (Henry BJ Phiri, pictured above, centre) – he’s attached to “Tourism and Traditional Beliefs” – who exploits the girl for money, making her adjudicate village disputes or perform to bring on rain. He’s not actually cruel to her, though: his own wife is a “reformed” witch, having earned nominal respectability “because I did everything I was told” (she puts her bobbin in a supermarket trolley when she goes out).

This is a society in which superstition is a convenient garb for prejudice

Nyoni leaves the plentiful elements of mystery in her story to speak for themselves, not least because Shula remains the passive protagonist throughout, but there’s no escaping the fact that this is a society in which superstition is a convenient garb for prejudice. There’s an undeniable aesthetic consolation – not perhaps the right way of putting it – especially in the work of cinematographer David Gallego (previously seen in the no less strange jungle exploration of Embrace of the Serpent), whose compositions capture the arid beauty of the film's scrub landscapes and delight in its particular visual details. A score from Matthew James Kelly is dominated by treated Vivaldi effects for violin, complete with snatches of Schubert and Estelle’s “American Boy”. 

This DVD release includes two of Nyoni’s short films. From 2011, her 23-minute Mwansa the Great is a playful Zambia-set story of a village boy attempting to assume the mantle of his late father, in a family environment where the female presence, in the form his assertive younger sister, looms large. There are lovely moments that touch on the contrasting worlds of children and adults, a theme also there in Listen, from 2014. The 13-minute film, codirected with young Finnish-Iranian filmmaker Hamy Ramezan, was in Directors’ Fortnight too, its story of immigrant experience, and how past attitudes can’t be escaped even in new worlds, all the more chilling for the concentrated, formal control with which it is executed.

Overleaf: watch the trailer for I Am Not a Witch

Over 25 years since his modest inception as a parody sports reporter, Alan Partridge has become one of comedy’s most enduring icons. With a new BBC series expected in 2018, we were treated to a tribute (or Partribute, if you will) to the impressive and varied career of Norfolk’s favourite fictional broadcaster.

As we reach December, the year of Stephen King comes to a close with this 4K Blu-ray restoration of his very first film adaptation: Carrie. It was the first major success for Brian De Palma, Sissy Spacek and John Travolta, but how does the original high school horror hold up in the 21^st century?

Outrage knows no time barrier, as the world at large reminds us on a daily basis. So what better moment for the National Theatre to fashion for the internet age a stage adaptation of Network, the much-laureled 1976 celluloid satire about lunacy and, yes, anger in the televisual age.

Repetition can help clarity. It emphasises significance, and shines a light more directly onto something hidden. It can guide us gently into an area we might have otherwise circumvented, and urge us to stare at something for long enough to see beyond, and transcend previous, long-held opinions. It can also, of course, become very tired very fast and that was, sadly, the case with the third series of John Morton’s BBC mockumentary sitcom.

I’ve said it before and I’ll say it again: you have to be pretty silly to take Gilbert and Sullivan seriously. But even sillier not to.

Donald Trump’s electoral success was, we have been told, fuelled by the anger of the American working class. But how do you show that kind of anger on stage, and how do you criticise its basis in traditional masculinity?

Men playing boys playing girls, women and men, all female parts convincingly falsettoed and high musical standards as backbone: Sasha Regan's single-sex Gilbert and Sullivan has worked a special magic on Iolanthe and The Pirates of Penzance, HMS Pinafore and now The Mikado, not so much. Energetic song and dance are still in evidence.

Catfights can be entertaining, till the blood starts to flow – or, as in Onur Tukel’s brutal social comedy, you take turns putting your opponent in a coma. During three increasingly ritualised donnybrooks, Anne Heche and Sandra Oh batter past the title’s fetishising of female fights.

It’s a bigly Trump-fest over at the Donmar, with adaptor Bruce Norris determined to make Brecht great again – or at least pointedly contemporary.
