Dust off the record player: Idris Elba’s Eighties comedy In the Long Run (Sky 1) has returned for a second series. Loosely based on Elba’s childhood, the show brings us into the day-to-day life of a West African couple, their British-born son, and the community in their Leyton council estate.

Sir Lenny Henry, PhD and CBE, is scarcely recognisable as the teenager who made his TV debut on New Faces in 1975. He’s been a stand-up comedian, musician and Shakespearean actor, and even wrote his own dramatised autobiography for BBC One.

Apparently your odds of dying in a plane crash are about one in 11 million, while chances of death in a car accident are about one in 5,000. Therefore flying is theoretically safe, and supposedly getting safer. You wouldn’t know it from the TV schedules though, littered as they are with the likes of Air Crash Investigation, Seconds from Disaster and documentaries about Concorde’s hideous demise in Paris in 2000.

If there was ever a documentary that needed you to have good speakers on your TV setup – or good headphones if you're watching on computer or tablet – this is it. It maybe goes without saying that reggae needs good bass reproduction to appreciate, and in the case of this one the constant pulse of classics and obscurities was absolutely vital to the structure of the piece.

What did we learn at the end of The Capture (BBC One)? A rice jar is a good place to hide USB sticks. It’s possible to withhold the opening credits for 11 whole minutes. A green coat works exceptionally well with light blue eyes and shoulder-length auburn hair. And Ben Chanan, who originated the script and directed it himself, is a television dramatist to watch, and watch again.

Monday night’s first episode of this three-part series was a bit ordinary, as it introduced its cast of British recreational cocaine users and explained why their habit may be ill-advised.

What’s extraordinary about Bake Off is not just the staggering complexity of the cooking challenges, but the amount of technical shenanigans that go into turning it into a finished programme (actually, spoiler-averse Channel 4 had teasingly left the ending off my preview version of this week’s show, but you catch my drift).

“I want something Russian…” It’s with such a cry that Helen Mirren, bored by the bizarrely transgressive masked ball that comes at the close of the first episode of Catherine the Great, gets the dancing going: nothing from the imported fashions of Europe will do for her, and the music duly strikes up, a soupily romantic melody on violin, the quintessence, you might think, of mythic "Russianness”.

Five episodes ago, BBC One's The Capture set off at a cracking pace with the apparent abduction and murder of barrister Hannah Roberts by army lance-corporal Shaun Emery.

The themes of food and cookery have already been boiled until the bottom of the saucepan melted, but TV commissioning editors can’t stop searching for new twists in the formula. So how about this one – get a couple of prestigious superchefs, and challenge them to make a perfect copy of that famous mass-produced snack, the KitKat.
