Name this advert. Woman strolling the streets of Glasgow. “We Scots,” she says. “We’re something else. We’re friendly (shot of a local bamboozling tourists with directions), determined (brolly v horizontal rain), and we don’t take ourselves too seriously. Best of all, we’re always there for each other (cue elderly lady asking, “Are you lost, wee laddie?”).

It’s Susan Calman of course, punting the wares of a certain bank. The ad was mostly shot in Glasgow, and there is more of the comedian’s love for her home city on display in Susan Calman’s Great British Cities (Channel 5, Friday, 9pm). Make that adoration. How much does Susan love Glasgow? Let her count the ways.

Glasgow is the setting for the penultimate episode in the six-part series. The format calls to mind Who Do You Think You Are? with the focus on cities rather than individuals, but there is scope to be personal as well, which Calman duly grabs. As someone born and educated in the city and who still lives there, she says: “It’s not that I’m frightened of change, I just know where I belong.”

But does she know all the secrets and stories Glasgow has to offer? Slightly ashamed to say I didn’t. Calman, too, had her eyes opened to people and places that surprised her.

The first appointment on her “detective trail of discovery” is her alma mater, the University of Glasgow, where she hears about a previous student who blazed a trail for other women to follow. After that it is on to the world’s oldest surviving music hall, the Britannia Panopticon.

Calman learned only recently that her grandfather worked in the shipyards. A delve into the city’s golden age of shipbuilding follows, then it is on to Templeton’s carpet factory and the Mitchell Library. Finally, a local guide introduces Calman to “the original sassy Glasgow lassie”.

It’s a fact-filled, emotion-packed hour. Filmed in the summer, everything looks lovely in the sunshine to boot. Calman does the old place proud.

What a dear diary year Andrew Scott is having, and it’s only March. Widely acclaimed for his performance in the film All of Us Strangers, his one-man Uncle Vanya won him best actor at the Critics' Circle theatre awards. Now he gets to play one of the slickest villains in crime fiction in the eight-part Ripley (Netflix, from Thursday).

The latest adaptation of Patricia Highsmith’s classic The Talented Mr Ripley stars Scott in the title role, Johnny Flynn as poor little rich boy Dickie Greenleaf and Dakota Fanning as a watchful Marge.

In Anthony Minghella’s 1999 movie the three main roles were played by Matt Damon, Jude Law and Gwyneth Paltrow. Quite the espadrilles to fill, but Scott hasn’t put a foot wrong since his breakthrough parts in Sherlock (playing Moriarty) and Fleabag (the “hot priest”).

Minghella’s film was nominated for five Oscars, including art direction-set decoration, and costume design. In the Netflix series, writer-director Steven Zaillian (Moneyball, Gangs of New York) puts his mark on things by shooting in black and white. It looks great in the scenes in New York and even better when the action switches to Europe.

Mammals (BBC1, Sunday, 7pm) is the no frills, does-exactly-what- it-says-on-the-tin title of the latest Sir David Attenborough extravaganza. None of your Blue Planet or Life in Cold Blood for this six-parter. The starkness is fitting, though. As Sir David informs us, mammals are nature’s success story. When the asteroid hit Earth 66 million years ago, three quarters of animal life was wiped out. Not the mammals, though. “Highly adaptable and remarkably widespread”, they conquered all before them.

Sir David begins his study with a chimpanzee family settling down for the night in the treetops. Just like humans, you think. Yet most mammals thrive in the dark, using the hours before dawn to hunt and couple up.

The action is shot with night vision cameras so the viewer has a sense of what the animal is seeing. There is no blurring or impenetrable gloom; everything is as clear as day and the effect is quite magical. It’s like watching an animated film. Usual word to the wise, though: this being a nature documentary the scenes are not all sweetness and light.

Balancing the grisly sights are shots of almost ridiculously cute mammals at work and play. Stars of the show are the Fennec foxes of the Sahara. These tiny creatures, with their big eyes and even bigger ears, do their best to keep as far as possible from humans - always a wise move. To get any shots of them on camera is a rare achievement. To get the images seen here is borderline miraculous.

After Mammals finishes, switch over for Paul O’Grady’s Great Elephant Adventure (ITV1, Sunday, 8pm). The late and much-missed O’Grady loved elephants as much as he adored dogs. In the words of Bananarama, that’s really saying something. Here the cameras follow as O’Grady visits rescue centres in Thailand and Laos. The need for such centres speaks to the worst aspects of humans, but the staff who work in them, and O’Grady himself, are a reminder that there is hope for humankind yet.
