Jam review – obsession and resentment in the classroom

Debut play at Finborough Theatre about teaching and the unteachable hits a nerve

When TV drama tackles Britain’s class divide, the go-to working-class type is the northerner: gritty, blunt of vowel and partial to a deep-fried Mars bar. The first and perhaps only pleasant surprise in Matt Parvin’s debut play Jam, produced by the ever-adventurous Finborough, is that it’s set in Cornwall.

Decline and Fall review - 'a riotously successful adaptation'

★★★★★ DECLINE AND FALL, BBC ONE Evelyn Waugh brilliantly brought to TV life with Jack Whitehall and Eva Longoria

Evelyn Waugh brilliantly brought to BBC One with Jack Whitehall and Eva Longoria

Like many first novels, Evelyn Waugh’s Decline and Fall has a strong whiff of autobiography. It is a revenge comedy in which Waugh – like Kingsley Amis after him in Lucky Jim – transmutes his miserable experiences of teaching in Wales into savage farce.

Suzi Ruffell, Soho Theatre

SUZI RUFFELL, SOHO THEATRE Amusing take on how class defines us

Amusing take on how class defines us

Suzi Ruffell tells it straight: she's working-class and proud, but some people might think she's "common", which is the show's title. She has devised a quick quiz for us to check if we're working-class ourselves, and among the amusing tell-tale signs is: did your mum use to freeze milk? A new one on me, but the show is off to a good start.

John Berger: the critic as artist

JOHN BERGER: THE CRITIC AS ARTIST Remembering the influential and radical thinker who has died aged 90

Remembering the influential and radical thinker who has died aged 90

It’s hardly the lot of an art critic to be loved and admired, still less to speak to an audience that might reasonably be called “the public”. And how many will find their ideas still current 40 years on? All of these things can be said for John Berger, who has died aged 90, a man whose radical approach to looking at art was an absolute inspiration, and whose ideas were a solid presence in my childhood, woven into my early memories as surely as the pages of a photo album.

Half A Sixpence, Chichester Festival Theatre

HALF A SIXPENCE, CHICHESTER FESTIVAL THEATRE The Tommy Steele musical gets a triumphant, banjo-rehabilitating refresh

The Tommy Steele musical gets a triumphant, banjo-rehabilitating refresh

Watching Cameron Mackintosh’s joyful revision of this Sixties musical, it’s possible to believe for a moment that all the world needs now is love sweet love and a shit-ton of banjos. With a new book by Downton Abbey behemoth Julian Fellowes, new numbers by the pair behind hit musical Mary Poppins, and design that delights at every turn of the multi-revolve, Half A Sixpence seems destined to follow a flush of previous Chichester Festival musicals into the West End. It also puts vintage stars around the previously unknown name of Charlie Stemp.

The Violators

THE VIOLATORS Ballsy, bruising, brilliant directorial debut feature from novelist Helen Walsh

Ballsy, bruising, brilliant directorial debut feature from novelist Helen Walsh

British filmmaking does gritty suburban dramas better than anywhere. Stories stripped of superficial action, from Ken Loach’s early work through to more recent stand-out films like Tyrannosaur. The Violators offers a new voice producing a superb feature set in a bleak Merseyside suburb. Debut director Helen Walsh is better known as a novelist, creating tales thick with human drama, sometimes in grim settings, and The Violators adheres to this template.

Normal for Norfolk, BBC Two

NORMAL FOR NORFOLK, BBC TWO Posh doc about East Anglian farmer clinging to the wreckage provides blameless fun

Posh doc about East Anglian farmer clinging to the wreckage provides blameless fun

In 2014 the Channel 4 series Confessions looked at the changing face of the old professions. In the programme about doctors, one GP remembered the standard practice of deploying acronyms on patient notes that looked like arcane medical terminology but were in fact nothing of the sort. One of them was NFN, which meant Normal for Norfolk.

Arnold Wesker: His Life and Career in 10 Scenes

ARNOLD WESKER: HIS LIFE AND CAREER IN 10 SCENES The angry young playwright's career was as dramatic off the stage as on

The angry young playwright's career was as dramatic off the stage as on

Of all the dramas with the name Arnold Wesker attached to them, the most absorbing ran as long as The Mousetrap, but offstage rather than on. It was in the style of a remorselessly black farce, in which the little man as hero suffers an endless series of blows, reverses and pratfalls. Some are minor, some cataclysmic, but they all have one thing in common: they fail to deter their victim who, like one of those clown figures mounted on a toy rubber ball, always rolls back into the upright position.
