The thing almost no one remembers about the great Nora Ephron/Rob Reiner 1989 romcom When Harry Met Sally is that the love story is intercut with real couples talking to camera about the mechanics and longevity of their true-life loves. It shouldn’t work, but it does. Remarkably, Fergus O’Brien’s deeply moving BBC film Against the Law, armed with far darker material, pulls off the self-same trick.

Presumably it seemed like a good idea at the time.

“The northern white rhinos are just a symbol of what we do to the natural world,” as one of the contributors to this haunting documentary put it. “We witness them disappearing in front of our eyes.” The programme ended with names of endangered animals jostling for space on the screen, from hawksbill turtles and the South China tiger to whales, orangutans, the red panda and the snow leopard.

Immigration…immigration… immigration… that’s what we need! Not the words of record-breaking, tap-dancing trumpeter Roy Castle, rather it’s the gist of a Times leader from 1853 (admittedly, fairly heavily paraphrased).

There has always been an air of incipient doom hovering over Ripper Street, since the show is more of a laboratory of lost souls than a mere detective drama.

Playwrights have long migrated to the small screen in search of better pay and room to manoeuvre. Most don’t leave it as long as Conor McPherson, who was perhaps cushioned from necessity by the global success of The Weir. A quarter of a century after his stage debut, Paula (BBC Two) is his first go at television drama.

In the dog-eat-dog world of White Gold it’s 1983, when greed was about to become good and (as the show’s creator Damon Beesley puts it) “a time when having double-glazed patio doors installed meant you were winning at life”. The streets were full of sludge-coloured cars from British Leyland, and Duran Duran and Bonnie Tyler ruled the charts.

Imagine a doctor has just told you that you have only a year to live. What would you do? Learn to sky dive, spend every last penny you have, be brutally honest with anyone who has crossed you, or curl up in a ball and wait for the inevitable? Producer and director Sue Bourne decided to talk to people who have indeed been told they have only a little time left, and A Time to Live on BBC Two is the remarkable result.

Do you ever wonder what you’d do if you were given a terminal diagnosis and told you may only have months to live? That question is what my latest film is all about. It may sound maudlin and sad but I can assure you it isn’t. And the reason for that is that the people I set out to find may have been terminally ill but they’d all chosen to make the most of the time they have left. The film is honest, uplifting, thought-provoking and, I hope you don’t mind me saying this, it’s also pretty remarkable.

Actor Oliver Chris, who plays William in Mike Bartlett’s ingeniously-crafted play about the monarchy, was doing some pre-transmission fire-fighting by going round telling interviewers he couldn’t see what anybody (eg the Daily Mail) could find to get upset about. Why would they?
