Derek Jacobi

"We're not burglars, we're pensioners," cries Celia (Anne Reid), spooked by the creaks and groans of Southowram Hall where she and Alan (Derek Jacobi) remain locked in. Their families are frantic over the couple's whereabouts, but the panic brings their respective daughters closer together and a tentative friendship is formed. Sally Wainwright's comedy-drama has charm in abundance, its chief joy the pairing of Reid and Jacobi, particularly delightful in tonight's episode when they spar off each other over a candlelit game of cards.

Aged lovebirds Celia and Alan (Anne Reid and Derek Jacobi) potter happily through their new life together as their families fall apart around them. Celia's brittle daughter Caroline (Sarah Lancashire) rages against the infuriating and inept drunken man of straw she married, while Alan's daughter Gillian (Nicola Walker) is humiliated by that nasty piece of work she's sleeping with.

This all sounds desperately soapy, but it isn't, though things get a bit weird by the end with some nonsense about a haunted country house that feels like it belongs in another drama altogether.

Still, writer Sally Wainwright likes to spring surprises (and there are quite a few of those in this episode) as Alan and Celia take the next step in their relationship. Caroline, meanwhile, drops her guard in that lovely big house in Harrogate so we glimpse the well of loneliness that lies beneath her flinty exterior.

The classy silvery romcom continues. The vicar refuses to let Celia (Anne Reid) and Alan (Derek Jacobi) marry in church - well, neither of them has attended church since 1977 - so the second-time-around lovers go in search of venues for a civil ceremony. Soon they end up trapped inside a creepy medieval mansion in a storm, telling each other ghost stories. Elsewhere Gillian (Nichola Walker) tells John (Tony Gardner) he needs to stick up for himself, prompting him to return to Harrogate and tell Caroline (Sarah Lancashire) that he's moving back in.

Celia and Alan (Anne Reid and Derek Jacobi) are having a ball as the late-blooming romance drama beds in. They're racing through the gears of the relationship that escaped them 60 years earlier and, while their daughters are less than impressed, nothing touches Celia's wastrel son-in-law, John. Played by Tony Gardner, he is as gloriously dissolute here as he is creepy as Fresh Meat's Professor Shales.

Anne Reid as newly betrothed Celia has such a quiet-killer way of delivering a line; when her spineless twerp of a son-in-law gleefully explains the torrid sexual relationships in his latest book she fells him with, "Oh well, there we go." She might as well have shot him with a bow and arrow. Celia later explains to her fiancé, Alan: "He writes novels... they're nowt."

As Sally Wainwright's flinty romantic drama picks up pace, Celia and Alan (Derek Jacobi), reunited after 60 years, are planning an engagement party. Their respective families are still angry and baffled that the pair so suddenly decided to marry. Celia's unhappy daughter, who recently dabbled with lesbianism and who even more recently took back into her home the adulterous, novel-writing spineless twerp (the brilliant Tony Gardner), is particularly furious. But Celia and Alan don't care, they are too busy buying a sports car.

Celia (Anne Reid, mumsy with a hint of steel) and Alan (Derek Jacobi, twinkly with a hint of melancholy) are unbowed by the uniform opposition of their families to their engagement. In fact, while their children's private lives crumble (affairs, betrayals, midlife crises), their own bond looks stronger than ever. But could an engagement party reopen old wounds? As a portrayal of old age, it's not exactly 'Amour': the narrative signposting is constant and occasionally distracting. But what could have been whimsical - bordering on twee - is lent integrity by Sally Wainwright's characterisation, dignity by Reid and Jacobi, and drive by the goings-on among the excellent supporting cast, with professional scene-stealer Tony Gardner's oleaginous cheat as the stand-out.

Celia and Alan's touching whirlwind romance has been 60 years in the making. After dropping the bombshell on their children at the end of last week's episode that they're getting married, the newly engaged couple - played by Anne Reid and Derek Jacobi - have some exciting plans to make.

Not to mention bridges to build between their daughters Caroline and Gillian, who didn't get off on the right foot. "Trailer trash" and "b****" isn't the best way to greet your prospective in-laws.

So Alan and Celia decide to throw a little ­engagement party, which, as things turn out, should at least take the heat off their romance and stop it from being the sole topic of chat for a while.

This wonderfully bittersweet comedy drama from Sally Wainwright about love among the over 70s ticks all the right boxes thanks to sympathetic writing and excellent performances with depth.

Underneath Celia's twinkling optimism and girlish delight there lies a lifetime of experience and, when she puts a patronising young salesman firmly back in his box tonight, we can see exactly where her daughter Caroline (Sarah Lancashire) gets her take-no-c**p attitude from.

One scene tonight where Caroline cuts a meddling colleague down to size makes you want to stand and cheer.

Caroline's estranged husband John (played by Tony Gardner, who also plays Professor Shales in Fresh Meat) is back in the family home, but the appearance of his other woman (Ronni Ancona) is about to rock that little boat, too.

It's not often that a TV comedy comes along that's geared towards older viewers, but Last Tango in Halifax's such a show - and it's surprisingly good.

Set in Yorkshire, the story follows two OAPs, Celia and Alan (Anne Reid and Derek Jacobi) who used to be close school-friends, but drifted apart after school, got married to different people and ended up widowed. The two then rediscovered each other on Facebook and arrange to meet up for the first time in 60 years.

Last Tango in Halifax's a comedy drama so don't expect it to be laugh a minute, because it isn't. However, what it lacks for in jokes it makes up for in surprise. The first episode, for example, sees (amongst other things) a boy getting seriously injured after falling off his motorbike and a mother accused of killing her husband.

The main plus point for Last Tango in Halifax, though, is that while you think that it's going to be very predictable, it turns out be more complicated than you think. For example, I knew that one of the characters in the show was bisexual. In the first scene one of Celia's grandsons is reading Anthony and Cleopatra and I thought, "Oh, don't tell me they made the intellectual bookworm the bisexual one, with some gushing coming out scene to his headmistress mother." But no, it turns out that the bisexual one is in fact the said headmistress mother Caroline (Sarah Lancashire), so I was certainly taken aback by that.

The other falsely-predictable moment occurs when Alan parks his car up in a car park before meeting Celia. He doesn't buy a ticket to use the car park and just walks away, leading me to think, "Oh, don't tell me that he and Celia are going to go back to the car, only to find being in the middle of being towed away or clamped." Again, I was wrong. Instead he goes back to buy the ticket, and finds some smashed up glass where his car was, as it's stolen. This in turn leads to the funniest sequence in the opening episode, where in Celia's car they discover Alan's stolen car being driven and the two go in hot pursuit of it across Skipton.

While I wasn't expecting much, it turns out that this has been a rather charming, warm, surprising programme. Certainly worth watching, considering the plot developments that occur at the end of the first episode.

Despite its charm it was difficult to see how Sally Wainwright's romantic comedy could sustain itself for another five episodes after ageing Yorkshire love-birds Alan (Derek Jacobi) and Celia (Anne Reid) announced they were getting married last week. Fear not, though, this second part proves just as engaging as the back stories of the extended families led by their put-upon daughters, headmistress Caroline (Sarah Lancashire) and farmer Gillian (Nicola Walker), develop into an entertainingly fraught family saga.
