Everyone (well, almost everyone) can tell a joke. But being a comic – holding an audience rapt, getting a roomful of strangers to like you and laugh at your material – takes real talent. So this is an interesting wheeze, in aid of Stand Up to Cancer, where five comedians mentored five celebrity beginners for two weeks so they could perform five minutes of material before a live audience.

Belfast-based thriller Bloodlands comes from the pen of first-time TV writer Chris Brandon, though he may find some of his thunder being stolen by the show’s producer, Line of Duty supremo Jed Mercurio. Line of Duty is filmed in Belfast too, though it doesn’t advertise the fact on screen. Bloodlands, on the other hand, is steeped in its northern Irish locations both rural and urban, as it unravels a dark and twisty tale of the legacy of the Troubles and how the past has an ugly habit of coming back to poison the present.

A story of obsession, media madness and the price of fame, as well as a filmic incarnation of Jim Morrison’s “bloody red sun of fantastic LA”, Matt Yoka’s film Whirlybird is a strange and fascinating hybrid.

Based on a book by Roberto Saviano, author of the Neapolitan gang saga Gomorrah, ZeroZeroZero (Sky Atlantic) is an account of the international drugs trade and the way its tentacles wrap themselves around the entrails of societies at all levels.

The theme of a parent haunted by the loss of a child can have powerful dramatic potential, and this is the premise behind The Drowning, Channel 5’s new four-night mystery. Nine years earlier, Jodie and Frank’s four-year-old son Tom vanished during a family outing to a local lake. His body was never found, and he was presumed dead.

Isabella Pappas was nominated for an Olivier Award seven years ago – before she’d even started secondary school. The 18-year-old now stars in ITV’s new comedy-drama about grief, Finding Alice, opposite Keeley Hawes, Joanna Lumley, and Nigel Havers.

If this had to be the end of Spiral, the final episodes of Series 8 (BBC Four) at least ensured that justice was done. We saw evidence that on occasion lawyers may be human after all, and there was even the somewhat disorientating semblance of a happy ending (or at least not the bloodbath that had threatened to erupt).

Anna Friel’s unstable detective Marcella Backland has been on the brink of existential burn-out ever since her first appearance on ITV in 2016, but it seems audiences have a perverse desire to see what psychological black holes she might plummet down next.

Polly Walker's character in Netflix's sumptuous new Regency romance, Bridgerton, could've easily been little more than a villainous Mrs Bennet. We meet Lady Featherington as she's forcing one of her daughters into a tiny corset, muttering about how she could fit her waist "into the size of an orange and a half" when she was the same age.

Finally, it seems, the time is right for a major British TV drama about how the AIDS crisis hit the early 1980s London gay scene.
