The issue of public inquiries into the conduct of the military is in the headlines again, with a current focus on Northern Ireland, but at the centre of screenwriter Robert Jones’s Danny Boy was the attempt to find British soldiers guilty of war crimes in Iraq.

Nick Broomfield made his first film 50 years ago, and his career over those five decades (and some three dozen works) has been as distinctive, and distinguished as that of any British documentary maker.

Admittedly, Antarctic explorer Captain Scott was at the other end of the earth from the protagonists of The Terror (BBC Two), but they would surely have concurred with his anguished observation: “Great God! This is an awful place.” Based on Dan Simmons’s novel, The Terror is a fictionalised account of the 1845 attempt by Sir John Franklin to find the Northwest Passage between the Atlantic and the Pacific via the Arctic Ocean.

Back to Georgian brothels, now – at least, for those of us who don’t have a Hulu subscription. The BBC’s airing of the second series of Harlots over the summer felt strangely timely. Barely an episode in and an angry crowd was hammering at the local judge’s door, demanding justice after the needless death of one of the city’s poorest residents.

Enlisting Hollywood giant Samuel L Jackson to host a series about the history of slavery, his own ancestors having been trafficked from West Africa to the Americas, was a headline-grabbing move, and scenes where we travelled with Jackson to the historic slaving hotspot of Gabon rang with a steely sense of commitment.

Stories of the destruction of the natural environment are depressingly common, but Frank Gardner brought a fresh slant to this punchy account of a botanical expedition to Colombia (BBC Two). Best known as the BBC’s security correspondent, Gardner was partially paralysed in a terrorist attack in Riyadh in 2004, but was determined that this wouldn’t stop him.

The story of the malignant fantasist Carl Beech is one of the more iniquitous episodes in British legal history, a stomach-turning swamp of lies, gullibility and heinous incompetence. It shook faith in some of our supposedly most robust institutions to the core, and Beech’s lies tainted the reputations of some innocent victims who went to their graves with a shadow still hanging over them.

Mandy started life in the Comedy Shorts season last year, and has now been given a six-part series. Diane Morgan, who has a solid CV in other writers' work including Philomena Cunk, Motherland and After Life, here writes, directs and stars as the title character, who has a messy beehive, always wears thigh-high boots, has a fag on the go and a face set to permanent grimace.

Sun bears and moon bears are probably doomed, so why bother? Wildlife trafficking is a hugely profitable worldwide criminal enterprise, with small charities (fingers in the dyke, anyone?) doing their best to stem the flow.

As an opening line to BBC Two's new three-part series, “Rupert Murdoch is an enigma” failed to set pulses racing. It rather implied that after three hours of documentary TV, we may end up none the wiser about what makes the scary Australian media tycoon tick.
