Luckily, the budget for this two-part adaptation of Andrea Levy's prizewinning novel stretched to some location shooting in Jamaica. The contrast between the Caribbean's luminous skies and brilliant colours and crushed, monochrome, half-dead 1940s London is almost too painful to watch. It's the perfect visual metaphor for a story about Technicolor dreams crashing to earth

At the end of series seven, our tight-lipped MI5 squad risked designer shoe leather and impeccable coiffure to defuse a Russian atom bomb in London, and their boss Harry Pearce (Peter Firth) was kidnapped by dubious Russian agent Viktor Sarkisian. Hence series eight began with the hunt for Harry, whisked (unbeknown to his underlings, who expressed their concern by smiling even less than usual) by helicopter to a mansion in “Moscow on Thames”.

In Garrow's Law: Tales from the Old Bailey, writer Tony Marchant has turned to the real-life archives of the Old Bailey to find cases to illustrate the pioneering legal work of William Garrow. In the late 18th century, courtroom trials bore more resemblance to bear-baiting or witch-finding than to anything connected with justice or due process.

Lesley Sharp could be thought of as an actor's actor: a talent equally at home in theatre, cinema and TV who has been impressing audiences and critics regularly for a quarter-century without quite becoming a star name.

You can only assume they decided to confront the, er, generously proportioned mammal in the room. ITV launches a new police procedural starring the star of an old police procedural. Said star is a sizeable Scot with an old Toby jug of a face and, oh sod it, let’s just admit we’ve cast him because of the baggage. Yes, Cracker is back. OK, not Cracker, nor even Fitz, but a lived-in Glaswegian high-rise of a man who cracks murder cases on primetime, pausing only for the commercial breaks. It’s almost as if the young witness already knows all about Robbie Coltrane. “I’ve seen you before,” she says in the incident room. “Yeah?” he drawls. “I’ve been in the papers a few times.”

Hung is about a teacher with an enormous penis who becomes a gigolo, which might sound like prime Judd Apatow real estate, but is a surprisingly tender foray into the male and female sexual psyches.  Part two of HBO’s current male midlife crisis fixation is a completely different kettle of fish-out-of-water to Eastbound & Down – quirkier and less boisterous – and its pedigree (written by the creators of The Riches and shot by the director of Sideways) tells you a lot of what you need to know.

Is HBO trying to tell us something? Is the once peerless cable channel signalling a midlife crisis? I only ask because Hung, the HBO comedy-drama that starts on More4 in mid-October, features a marginalised middle-aged basketball coach who turns to prostitution, while Eastbound & Down is about a Major League baseball pitcher who, “several shitty years later”, finds himself teaching PE back at his hometown high school.
