It took the best part of six episodes, but we got there in the end: the reason David Oyelowo accepted the confusingly underwritten part of Inspector Javert in BBC One’s adaptation of Les Misérables was finally revealed.

When British sitcoms head west anything can happen. For every success – The Office had a happy second life with Steve Carell – there are half a dozen others that got lost in translation, including Coupling, Getting On, Gavin and Stacey, The It Crowd and The Vicar of Dibley.

When they were children the interviewees in this film – the last survivors – were taken away in incomprehensible circumstances, on their way to be murdered for who they were, in Germany and places further east.

How does an unassuming 36-year-old with a terrifyingly sensible haircut and a mildly flamboyant taste in jumpers become the political playwright par excellence of his generation?

Reckless, unstoppable, one step ahead of everyone else, a hell of a lot of fun, utterly charming, street smart – descriptions of the artist Sidney Nolan (1917-1992) poured out from colleagues, rivals, curators, art historians and dealers, not to mention friends and family, in this persuasive film.

The multi-costumed Lucy Worsley is television marmite, loved or loathed: her gesticulating enthusiasm can grate, as can her stream of bland platitudes. Typically the title is Worsley-twee, evoking fibs instead of lies and falsehoods; are we in the nursery, as smart Nanny Worsley seems to think?

Perhaps inspired by the success of the revived Hawaii Five-O, CBS and Universal have gone back to the Eighties, and back to Hawaii, to see if the venerable Magnum P.I. could benefit from a similar overhaul. Early evidence suggests that as formulaic American dramas go, it’s… sort of business as usual.

How much more is there to say about the thrills and spills of midlife? Cold Feet made a surprisingly nimble return to ITV a couple of series ago after a long furlough. There was little evidence of stiff joints or saggy bottoms in Mike Bullen’s writing as he welcomed a gang of teens to the cast list.

On Drums was inhabited by a parade of fine-looking young and middle aged multi-ethnic anglophone drummers, all introduced by Stewart Copeland, the American drummer of the Police. In vintage film and contemporary interviews his chosen musicians seemed almost invariably fit and trim whatever the substances ingested in the past.
