If Britain has created a national myth about slavery, it’s surely been centred on the pioneering abolitionists whose actions in the early 19^th century led first to the ending of the slave trade across the British Empire in 1807, later to the abolition of the institution in 1834. It’s a record of which, compared to the approach of other nations to the same issue (and the speed of their actions), we may even feel a hint of pride.

When least expected, comedy has come stumbling into the work of French auteur Bruno Dumont. In his seven films to date, from the Cannes-winning Humanité of 1999 through to the stark Camille Claudel 1915 from two years ago, the director, frequently working with non-professional actors, has marked out a distinctive territory defined by its bleakness and emotional intensity.

US films about and aimed at African Americans broadly fall into two categories: gangsta life in the ‘hood action flicks and broad comedies, the latter niche dominated by Tyler Perry, who does for Black Americans what Mrs Brown does for Irish women. Dear White People, on the other hand, is a sophisticated social satire in the vein of Spike Lee’s early She’s Gotta Have It or Bamboozled.

The clue is in the name: Selma, after the Alabama city that was the site of three crucial confrontations in the 1960s struggle for African-American civil rights, not King, after the eloquent spokesman and de facto leader of that struggle. Because director Ava DuVernay is more interested in saluting the power of a grassroots movement than in lionizing a Great Man of History, this inspiring, profoundly moving film avoids the pussyfooting and over-reverence that has afflicted biopics of other secular saints like Gandhi, Lincoln, and Mandela.

Shami Chakrabarti (b. 1969) is the director of the civil liberties organisation Liberty, a position she famously and, some would say, fortuitously took up the day before 9/11. Raised in suburban north-west London, she became a barrister for the Home Office in the mid-Nineties. Regularly voicing her opinions on a multiplicity of current affairs programmes, notably Newsnight, she has spoken out on a huge number of issues, especially taking a stance against Britain’s “anti-terror” legislations.

You might think you know what you’re in for with a play by Anders Lustgarten, winner of the inaugural Harold Pinter Playwright’s Award and current go-to political activist for the Royal Court and the National. Listed alongside the plays on his CV is the boast that he’s been “arrested in four continents”.

The story of the 1964 Smethwick election, with its unofficial Tory slogan, “If you want a nigger for a neighbour, vote Labour,” is well known. The successful Conservative candidate, Peter Griffiths, subsequently became MP for Portsmouth North, 1979-97, where he advocated the similarly opportunistic but less controversial cause of the naval dockyards, and died in 2013. What really shocked about this often eye-wateringly revealing documentary was the extensive footage of the caustic casual racism prevalent at the time.

With a similar title to Samuel Fuller’s White Dog, White God, too, is an allegory on racism with a canine slant. Where the 1982 film centred on a dog trained to attack black people, Kornél Mundruczó’s film is set in a Hungary where mixed-breed dogs are rounded up and sent to pounds. An edict from a government which is neither mentioned specifically nor seen, permits only pure “Hungarian” breeds. Mutts have to be reported.

Plays about Muslims in British theatre tend to open a door on a segregated community, a place cut off from the mainstream. But stories that show cultural conflict – between whites, Asians, Muslims, Hindus, Poles and Sikhs – are much rarer. So it’s good that actor-turned-playwright John Hollingworth’s debut play, with a title which alludes to Walt Whitman’s “I am large. I contain multitudes” from Song of Myself, dares to explore conflict between social groups.

As worst-case scenarios go, the prospect of a UKIP government in a little under three months’ time is a frightening but unlikely one – isn’t it? That they have only two MPs, and leader Nigel Farage is yet to find a seat, has done nothing to stop UKIP setting the political agenda, bulldozing its way to centre stage to demand a place in the forthcoming televised election debates.
