If you were a fan of Porridge (and if you've seen the 1970s prison-set comedy series you ought to be), then you'll know who Lennie Godber was. Godber was the gullible and studious young cellmate of Norman Stanley Fletcher, one of Britain's best-loved criminals. Unlike many actors whose egos get in the way of their good sense, the portly Ronnie Barker - a popular and talented man who brought Fletch to life - retired from a hugely successful and varied showbusiness career at pensionable age and bought an antique shop in a market town in England. Sadly, the life and career of Richard Beckinsale, the dark-haired actor who played Godber, was cut tragically short when he died from a heart attack while in his 30s. Fortunately, his acting legacy lives on in his pretty daughter, Kate, the star of Jane Austen's Emma (Pearl, 9.30pm). To date, Beckinsale has achieved her greatest exposure in Kenneth Branagh's Much Ado About Nothing. This Emma is not the recent Hollywood adaptation with Gwyneth Paltrow, but a reliable and relatively low-key British production. Beckinsale plays Emma Woodhouse, the heroine of Austen's romantic and trifling tale about love, hopes and marriage. After Emma's beloved governess marries, she quickly befriends the pretty but pliant Harriet Smith; her aim, to improve and help her rise in society. At Emma's suggestion (and much to the vexation of Emma's brother-in-law Mr Knightley), Harriet turns down an offer of marriage to an eligible young farmer, Robert Martin. Emma plans for Harriet to marry Highbury's vicar, Mr Elton. However, Emma is mortified when Mr Elton proposes to her instead. Her scheming is scupperd further when two new faces, the beautiful but reserved Jane Fairfax and the dashing Frank Churchill, arrive in Highbury. Of course, this is vintage Austen and all turns out well, each character paired off with the partner God intended. The production starts slowly but soon kicks into gear as the characters intermingle. Beckinsale is as spirited and youthfully naive as she ought to be and Mark Strong as honourable, gentlemanly and confident as the charming Mr Knightley. And talking of daughters - Eloise, the offspring of the most famous musketeer, is the subject of D'Artagnan's Daughter (World, 9.30pm), a film from director Betrand Tavernier. Sophie Marceau plays the passionate young woman whose blood, like her father's, courses with honour, loyalty, love for the poor and a lust for life. Her quest: to avenge the death of the mother superior of her convent who is killed for trying to protect a desperate slave on the run from the clutches of the odious Duc de Crassa (Claude Rich) and his evil muse, the woman in red (Charlotte Kady). Inevitably, D'Artagnan (Philippe Noiret) and his now portly companions, Porthos, Aramis, Athos and the faithful Planchet, become involved in the swashbuckling outing. However, their swordsmanship is not what it was. The ever-present threat of neighbourhood crime has prompted Victor and Margaret to step up security on their Riverbank home - with predictably disastrous results in tonight's One Foot In The Grave (World, 6.30pm). When new locks and bolts jam, they can't even open the backdoor without the aid of a crowbar. How will Victor break out of the house in time for his trip to the European Cup quarter-final at Wembley? Meanwhile, Mrs Warboys has gone to Blackpool to visit her sister, who is in a state of shock after having her head sawn off on stage at the resort's Winter Gardens.
