Barbara Windsor’s laugh belongs in the National Sound Archive. It’s a birdlike chuckle that wavers between innocence and dirt. We all know Babs’s laugh. But what about her tears? There have been plenty of those too according to Babs, BBC One’s feature-length drama which sifted through the jigsaw pieces of a tumultuous life spent in the public eye.

In the midst of a general election campaign and with Euro-shrapnel flying around our ears, it’s an intriguing moment at which to revisit Britain’s history as a nuclear power. Although this film from BBC Science concentrated on the factual and technical aspects of building the British atomic and hydrogen bombs, the story was inescapably entwined with power, politics and national identity.

So here’s the thing: a heavily pregnant woman is hanging by her ankles above a raging torrent. Two teens, one with a broken arm, are stuck down a well. And 15 miners, deep below ground, take refuge from a fire in an emergency chamber, unaware it has been sabotaged by the serial killer among them, who then, using “a gadget”, proceeds to switch off the mine’s pumps so they will all slowly drown.

Cop a load of that, then. Hana Reznikova is serving time for triple murder. Ted Hastings is on permanent gardening leave. The Huntleys have renewed their wedding vows on a family trip to Disneyworld. Just kidding. This is a Reg 15 alert to advise you that the following paragraphs contain almost nothing but spoilers.

The simplest ideas are often the best. Here’s one – take AC/DC’s Tyneside-born vocalist Brian Johnson and get him to chew the fat with a list of fellow rock’n’roll veterans. Later in the series he gets to meet Sting, Nick Mason and Lars Ulrich, but for this first show (on Sky Arts) the guest was Roger Daltrey of The Who.

If Robert King and Michelle King, creators of The Good Wife, took the Joss Whedon line on sequels – “They are inevitably awful” – then we would not have The Good Fight (More4) gracing our screens. But, thankfully, this sequel (actually, more a spin-off) is far from awful – it's very, very good. You could say this is Frasier (born out of Cheers) rather than Joey (Friends).

Turning the real-life murder of an 11-year-old boy into a four-part TV drama carries obvious risks (might it be exploitative, sick or in bad taste, for instance?), but judging by this opening episode of Little Boy Blue (ITV), screenwriter Jeff Pope has skilfully walked the line.

“Take your pick. Who shall we talk to first?” DI Alec Hardy (David Tennant) and DS Miller (Olivia Colman) had their three prime suspects waiting for them in custody.

It was a long time coming, but Homeland’s sixth series at last awoke from its early-season slumbers to put on a late surge over the closing episodes. For a while, it had seemed that the story was barely advancing at all, as the screen was self-indulgently hogged by Carrie Mathison’s emotional life, particularly her anguish over her daughter being taken into care.

We’re three films into Rowan Atkinson’s tenure as Inspector Maigret and so far he’s barely twitched a facial muscle. Gone are the eye bulges and nostril flares, the rubbery pouts. There’s sometimes a hint of a frown, the odd twinge in a wrinkle around the eyes, but Atkinson’s performance continues mainly to be about keeping his cards superglued to his chest. Gnomic is about the size of it.
