It's interesting to consider at what point in someone's career does he or she become a national treasure - as Alan Bennett once so scathingly remarked, “If you live to be 90 in England and can still eat a boiled egg they think you deserve the Nobel prize” - but there can surely be no debate about whether Dame Judi Dench deserves her status.

Geoffrey Palmer said of his co-star for several years on the BBC sitcom As Time Goes By, “She's everything that everyone says about her” - and what they had to say about her in Charlie Stuart's The Many Faces of Dame Judi Dench was overwhelmingly nice; she's a joy to work with, a stellar presence on screen and stage, and a jolly presence in the rehearsal room.

The film was an enjoyable, if undemanding run-through of Dame Judi's career and, although billed as a documentary, there was little by way of personal biography. For the record, she was born into a Quaker family in York in 1934 and made her professional debut in 1957 with the Old Vic Company and hasn't stopped working since. Palmer was among a long list of talking heads who included Michael Parkinson, Ronald Pickup and Simon Callow, and a smattering of critics, but she was noticeably absent from the programme, and the clips perforce were mostly of her television work and some recent films.

Much was made of her wide range of credits as one might expect from an actress with an extensive and varied CV. Palmer, an old friend who made some drily mocking contributions, explained, “She just likes working, so if someone offers her a job, she takes it. She’s crazy."

She has always, we learnt, moved with ease between stage, television and film, and - unusually for an acclaimed serious actor of her generation – has done as much popular entertainment as she has highbrow work, in a career dripping with awards, including an Oscar. Her longevity means that each generation discovers her for themselves; for many, she's the definitive Lady Macbeth (in Trevor Nunn's 1976 RSC production), or Sally Bowles (in the first London production of Cabaret in 1968), or Queen Victoria (in John Madden's film Mrs Brown, pictured right).

To a huge number of TV viewers she will be known as the kindhearted Miss Matty in Cranford (pictured below), and to filmgoers for a heartbreaking study of the novelist Iris Murdoch descending into the hell of dementia in Iris (2001), or as the positively evil Barbara Covett tormenting fellow teacher Cate Blanchett in Notes on a Scandal (2006). For me her definitive role was Titania played as Gloriana in Peter Hall's magnificent production of A Midsummer's Night's Dream in 2010. It was, simply, awesome.

Despite being made in DBE in 1988, Dame Judi's fame was confined to these shores until a trio of roles in films released in three years – M in Goldeneye (1995), Queen Victoria in Mrs Brown (1997) and Queen Elizabeth I in Shakespeare in Love (1998) – gave her worldwide stardom. As her Goldeneye co-star Samantha Bond remarked, Dame Judi become an overnight success in her sixties in the United States and some American journalists, unfamiliar with her extensive CV, innocently asked what she had been doing before M. Dame Judi had been offered Broadway roles when she was younger, but decided to stay put in Britain to look after her beloved husband, the late Michael Williams (her co-star in the BBC sitcom A Fine Romance) and their daughter Finty Williams, herself now an actress.

Much of Dame Judi's popularity, I suspect, comes from the fact that lots of TV viewers know her as a notorious corpser from her appearances on bloopers shows down the years - “We did have the odd retake...” attested Palmer - while director Sally Potter talked about the “weeping levels of hilarity” during the making of her film Rage (2009), when a young man had to be drafted in to tutor the dame in the art of smoking a spliff.

Others may quibble with Dame Judi's recently elected status in a trade newspaper as the greatest stage actress of all time – surely an impossible thing to judge, and one that I suspect she herself would bat off as silly – but as this programme showed, she is head and shoulders above her peers in the breadth of her roles. She's done everything from Shakespeare to Sondheim, sitcom to Z-Cars and Bond to Brecht. And even at an age where others might be retiring she is still taking on demanding and boundary-pushing work, such as her role in the experimental film Rage.

This was decent trot through an interesting and full career, and it was fun to see some footage of Dame Judi as a young actress. But ultimately her absence meant that the film lacked any meaningful analysis of her work.

There are all sorts of reality shows, but the best ones really do strip people bare. It’s the reason why The X Factor is more interesting than Strictly Come Dancing, why Don’t Tell the Bride is more revealing of the gamble of love than Snog, Marry, Avoid? It’s the reason why Masterchef: The Professionals is more gripping than the estimable Great British Bake-Off.

He would not hesitate to wake up employees at all hours to yak about ideas. He could fire an underling in the seconds it took for the elevator to ferry him to or from his fourth-floor office. He shouted, like, a lot, even at Bill Gates. Especially at Bill Gates. And yet the great and the good last night all queued to waft smoke up the posthumous iHole: Tim Berners-Lee, who invented the internet, Norman Foster, who invented the glass airport, Stephen Bayley, who invented designer waffle.

It’s not long until we’re told, “There is enough money in the world to make everyone in the world a millionaire.” And if everyone was? Utopia and freedom might not be inevitable. Inexorable price rises would restore some sort of balance. Or a crash might follow. But as this extraordinary look into what’s been inspired by the American money motivators who’ve washed up on our shores showed: logic, be damned.

There were those who laughed and those who spat outrage when Lloyd Blankfein, chairman of Goldman Sachs, said in a press interview that he was simply “doing God’s work”. Although Blankfein did have the insight to add that if he slit his wrists everyone would cheer, post-crash we would much rather our rich bankers expressed their religiosity by donning hairshirts and crawling on knees through broken glass - or at the very least stopped rewarding themselves so generously for the mess they got us in.

This is a very odd series. Even the BBC seem to be wondering what on earth they're supposed to be doing with it, since after the Wednesday night airing of these first two episodes Pan Am is moving to Saturday evening, with a Thursday repeat. 

Coming as it did over this Armistice weekend, when the soldiers who have died for us are foremost in our thoughts, last night's Art for Heroes: A Culture Show Special was a salutary reminder that soldier-victims are not just those who are killed or sustain terrible physical injuries but also those with psychological wounds which can't be stitched together. It went beyond, however, an exploration of Post-Traumatic Stress Disorder into how art therapy is helping some of these veterans process and express and salve their aggression and anxiety.

Those of us who regarded The Office as a work of comic genius (not a word I use lightly) will, I'm afraid, take some convincing about Stephen Merchant and Ricky Gervais's latest offering. Keen fans who have followed the duo's every move since that landmark sitcom will feel they know every last trope on display in Life's Too Short, from its mockumentary setting and unPC subject matter to dark comedy and celebrity guest spots.

Tubular Bells, the first half of which is being currently revived as a live piece in the UK, sold between 15 and 17 million units worldwide. Quite apart from the work’s innocence being co-opted and made spooky in William Friedkin's The Exorcist, there was something about Mike Oldfield’s first stab at quasi-symphonic rock which seduced the music-consuming public.

He’s been in the presence of murderers, rapists and paedophiles. He’s auditioned naked for a porn movie and submitted his tender midriff to liposuction. He’s spent more time than can be good for anyone in the company of Mr and Mrs Christina Hamilton. Yet it was only last night that, for the first time ever, audiences glimpsed Louis Theroux in a state of unvarnished terror. And fair play, he wasn’t afraid to show it.
