It took Picasso four years to learn to paint like Raphael, but it took him a lifetime to paint like a child, or so he said. For Brancusi it wasn‘t a case of relearning childhood, but of being careful not to lose it in the first place. “When we are no longer children we are already dead,” he said.

Brilliant though it was to be shooting an Imagine film for BBC One, we did experience the occasional tremor of foreboding about making a programme with Nigel Kennedy. We (that's me and director Frank Hanly) had a bit of previous with Nigel - I'd done several print interviews with him, and we'd shot a couple of short films with him for EMI.

The Doctor Who crew are fond of their encounters with historical characters. In his time, and let's face it he has infinite supplies of it, the Doc has rubbed shoulders with Shakespeare, Charles Dickens and Agatha Christie, and recently weathered the Blitz with Winston Churchill. For this one, "Vincent and the Doctor", le Docteur voyaged back to 19th-century Provence to straighten out a puzzling temporal kink.

Aptly, this new documentary about how the Rolling Stones fled from England to the South of France to record Exile on Main Street was premiered at the Cannes Film Festival, with a supernaturally healthy-looking Mick Jagger on hand to give it a promotional shove. Jagger (along with Keith Richards and Charlie Watts) produced the film, working closely alongside director Stephen Kijak to knit together an evocative and emotional portrait of "the greatest rock'n'roll band in the world", at what many would argue was their peak.

Idris Elba’s screen career is going so swimmingly that you wonder what can have tempted him back to Blighty. Probably not the weather, since the former denizen of Canning Town now lives in Florida, and is in perpetual demand Stateside thanks to the extreme hotness engendered by his portrayal of Russell “Stringer” Bell in The Wire. He was in the American version of The Office, co-starred with Beyoncé in Obsessed, has several movies in production and will executive-produce a new legal drama series for NBC.

Of course I’ve not been anticipating the appearance of the new Doctor with quite the counting-the-days excitement of many children, teenagers and anoraked adults across the land. But to invert the Jesuit motto, "Give me a child until he is seven and I will give you the man," my seven-year-old self has recently resurfaced, resulting in at least a frisson of excitement. After all, there’s also a new Tardis, a new assistant, some new bug-eyed monsters, and hopefully one or two scripts as scary as "Blink" or as inexplicably moving as "Human Nature/The Family of Blood".
