TV highlights 05/09/12

Who Do You Think You Are? 9pm, BBC1 Singer Annie Lennox plumbs her heritage, discovering a family on her father's side struggling to survive in her home town of Aberdeen and in Banff. Few opportunities emerged for her great-great-grandmother, given to a life of work before she was 10 years old after being orphaned. On her mother's side, however, fortunes were rather different: her grandfather William Ferguson was a gamekeeper at Balmoral who once danced with the Queen Mother. But a rather scandalous case of illegitimacy preceded such salubriousness. Ben Arnold Mrs Biggs 9pm, ITV1 Sheridan Smith plays the innocent young Charmian who, in 1957, meets the cocky, older Ronnie Biggs on a train and falls for his puckish twinkle. Daniel Mays is the young swaggerer who dresses in a suit for his commute, even though he works as a lowly carpenter. Adrian Scarborough is magnificent as Charmian's austere father and Smith further proves her chops as the helplessly-in-love ingenue. But the script feels a bit route-one, spoken by actors who are capable of so much more. Julia Raeside Dallas 9pm, Channel 5 In the 80s, it was illegal not to watch the oil-rich family's fights every week – and now they're back. Chief baddy JR gets a rough deal (he has been shipped off to a retirement home) but ex-wife Sue Ellen's still strutting around in a fabulous wardrobe with a face that hasn't changed in 20 years. They've now added a glossy new generation with John Ross (Josh Henderson) and little Christopher (Jesse Metcalfe) all grown up and following their dads' bitter rivalry. The young 'uns are sexy, champagne-slugging and covered in oil, thanks to the first drill on Southfork. Hannah Verdier Top Dog Model 8pm, ITV2 Rather disappointingly, this is not, as the title suggests, a competition to find the nation's most beautiful prisoner, but a search for a new canine supermodel. The X Factor-style judging panel is led by reality TV staple Stacey Solomon, which should give a fair indication of the quality of this show. David Walliams provides the innuendo-laced voiceover as primped pooches parade before the judges, who make incisive comments such as: "Oh, he's so selling that sailor outfit to me!" You'll need an unwavering love of dogs and talent shows to get through this one. HV Storyville: The $750m Thief 9pm, BBC4 Marc Dreier was a New York lawyer who assembled his seemingly successful business empire and extravagant lifestyle by stealing from clients and financial institutions. After pleading guilty, and while awaiting sentencing, he is placed under house arrest for 60 days, which is where his ex-employee Marc H Simon interviews him about his misdeeds. The resulting film is intriguing; Dreier is frank about his crimes and the way the fraud spiralled out of control, though it's hard to sympathise with a wealthy, vainglorious man who saw himself as entitled to his dream lifestyle. Martin Skegg Awkward 9pm, MTV Series one of Awkward was a smart, sharp high-school comedy with a Mean Girls/Easy A splash of darkness. As it returns for a second run, there's much to resolve, not least whether Jenna's own mother really did send the note that led to her daughter's suicide attempt (which wasn't really a suicide attempt). It's a shame, then, that this first episode revolves almost exclusively around the Matty/Jake love triangle – it's a stronger show when the focus is on wry comedy, rather than soppy, OMG teen romance.
