You can’t move for the World Wars on the BBC. Gallipoli (100 years ago) and VE Day (70) are this month’s on-trend anniversaries, and they’ll soon budge up for VJ Day and the Somme. And let’s not forget older victories: there’s Waterloo (200 years ago), and isn’t it time to go once more unto the breach, Agincourt being 700 this year? And for extra lashings of commemoration let us now turn to Britain’s Greatest Generation.

It is perhaps a clever piece of ironic perversity to have scheduled the first part of a three-part documentary on sharks on polling day, but the subject here is the comings and goings inside the complex world of the predators of the sea. The series is an amazing feat on the part of the BBC Natural History Unit, in tandem with the Discovery Channel.

The phrase “improbable life” crops up more than once in Greg Olliver’s highly engaging documentary Turned Towards the Sun about the poet Micky Burn (its title is that of the writer’s autobiography).

Agitprop is a term that seems to have dropped out of use. It has too many negative connotations; it smacks of political rant. Yet artistic director Neil McPherson, whose small and feisty Finborough Theatre at Earls Court receives no public funding whatsoever, has never pandered to delicate West London sensibilities, and I Wish to Die Singing: Voices from the Armenian Genocide, scripted by him, certainly doesn’t flinch from its task. This is, no less, to fill a gaping hole in the official history of the 20th century. Propaganda? You decide.

The past is a foreign country. Celebrities do things differently there. Programmes which put people in time machines and whizz them back to a less centrally heated era have been around for a while. Back in the day they’d pick on ordinary people and make them live as a skivs and drudges in some specifically benighted era before the invention of such new-fangled concepts as electricity or the flush mechanism or gender equality. But that was then. Reality in the jungle has turned us all into schadenfreude addicts, so now we get the same idea but with famous faces.

Remember the Hitler diaries? Stern and the Sunday Times were so eager for them to be true they went ahead and published even after historian Hugh Trevor Roper had changed his mind about their authenticity. Such was the hunger for stories about Nazis. It’s still there, but Die Welt was on firmer ground when – to accusations of sensationalism – last year it published extracts from the cache of letters, diaries and memos in the hand of Heinrich Himmler.

Dennis Marks, who has passed away at the young age of 66, was in every way larger than life. A talented and prolific music and arts documentary filmmaker, an inspired head of music for BBC Television, and artistic director of the ENO, he latterly reinvented himself as a consummately erudite and warm-voiced broadcaster who took his listeners on fascinating journeys down the Danube and along the Appian Way.

All the politicians lined up to chorus "Je suis Charlie" after the nauseating massacre of the Charlie Hebdo cartoonists in Paris in January, but three months later, how is that emotional declaration of solidarity against murderous extremism holding up? For this documentary, British Muslim Shaista Aziz went to Paris to find out.

Rude Boy is a rotten film. Nonetheless it exerts an inexorable draw as it includes live footage of The Clash which is amongst the best of any rock group on stage. The performance of “Safe European Home”, caught on camera in July 1978, is white hot. That is, the performance as seen. The audio track was subsequently modified in a recording studio.

Louis Theroux just wants to make good television. This may seem an obvious thing to say of a programme-maker, but many programme-makers concerned with the kind of human interest story that Theroux has made his own, often want to do more than this. They want to understand subject and motive, to get under the skin of a thing, or perhaps somehow resolve an issue. They believe, and sometimes perhaps they may even be right, that this in itself will produce good television, or at least go most of the way there.
