This documentary about the 1970s activist movement Rock Against Racism comes with festival prizes and much acclaim. It’s certainly a nostalgic feast for those old enough to remember when punk and reggae musicians were purposely united and it’s a timely release in the age of Grenfell, Windrush and Brexit.  

Fires are raging: by human agency – unthinking greed – in the Amazonian rainforest, by climate change, arson and accident in California and the American Northwest, and barely under control in Australia, another country whose leading politicians and media deny climate change.

If there was ever a balm for these confusing times, then it’s Max Richter’s Sleep, a lullaby of a documentary that explores the composer’s eight-hour-plus experimental 2015 composition based on sleep cycles. Richter is a remarkable musician and, alongside his experimental albums, has also been responsible for some of the most moving film scores of recent years, such as Dennis Villeneuve’s Arrival and James Gray’s Ad Astra.

Apart from her acting abilities, the qualities which made Sheridan Smith a star were her authenticity and lack of pretension.

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.

In 2018, directors Ian Bonhôte and Peter Ettedgui burst onto the documentary scene with McQueen, a visually stunning study of British fashion designer Alexander McQueen. Acclaim and offers followed, but no-one could have predicted the subject of their second feature.

“Manctopia” sounds like a blissed-out buzzword from the golden years of New Order and Happy Mondays, but in this four-part series (BBC Two) it’s used to describe the explosive redevelopment of Manchester.

During World War Two, President Franklin D Roosevelt described the USA as “the arsenal of democracy”. Only a couple of decades later, Fidel Castro was busily turning Cuba, only 100 miles from the US mainland, into the factory of revolution, exporting armed struggle around the world. It made his country a geopolitical player out of all proportion to its size, at the cost of violently antagonising the Americans.

On one level this documentary could be summed up as “parents have baby”, but since the parents in question are “Britain’s most prominent transgender couple”, it was a lot more complicated than that. Jake Graf used to be a woman and his wife Hannah was previously a man, and the path to having their first child caused them considerable soul-searching.

It was Alison Ellwood who directed 2013’s History of the Eagles, and now she’s at the helm of this new two-parter on Sky Documentaries, telling the story of the Los Angeles music scene from the mid-Sixties to the early Seventies.
