TV highlights 27/08/2012

Only Connect 8.30pm, BBC4 Quite possibly the best quiz show on TV – though Pointless might contest that accolade – Only Connect returns for another series of ferociously complex conundrums. For the uninitiated, it's the anti-Red Or Black, where clever people are tasked with finding connections between apparently disparate things. The puzzles are challenging enough to warrant wild living-room celebrations on the rare occasion where you get one right, while Victoria Coren just about manages to remain on the right side of annoying smart-arsery in the host's chair. Fun. Gwilym Mumford Horizon: How Big Is The Universe? 9pm, BBC2 The titular question would appear to be the very definition of unanswerable but, as this typically intriguing documentary demonstrates, there are boffins who beg to differ. Horizon meets cosmologists trying to create a definitive map of absolutely everything, a task that becomes ever more difficult as their tireless cataloguing proceeds further into the infinite. The conundrum they grapple with seems as much philosophical as physical: their latest research suggests that the universe may not be all there is, but the beginning of something even bigger. Andrew Mueller The Boyle Variety Performance 10pm, Channel 4 For those wondering what a variety performance hosted by Frankie Boyle would look like, here it be: an "entertainment extravaganza" featuring guest musicians and comedians such as Rob Delaney and Nick Helm. Boyle has also hinted this may be his final TV performance. And that being the case, it may apparently be even more controversial than usual! We wait with unbated breath. Ali Catterall Fraud Lord 10pm, More4 The extraordinary tale of Lord Edward Davenport or, as he should probably properly be known, "Lord" Edward Davenport. Davenport became notorious in the 80s for organising raucous raves for his fellow moneyed teenagers, experience he parlayed into a profitable line in event promotion, most famously at 33 Portland Place, the vast London residence he somehow acquired from the government of Sierra Leone. In 2011, Davenport was sentenced to seven years for his part in a multi-million pound fraud; his unrepentant website remains decorated with pictures of him with the stars who once came to his parties. AM Hunderby 10pm, Sky Atlantic As a black comedy-cum-period drama based on Daphne du Maurier's Rebecca, it's reasonable to point out that Julia Davis' first full series since Nighty Night isn't quite like anything else on television. It's also markedly different to her previous work, with a tight, playfully literary script accentuating the bizarre bleakness. A shipwreck survivor marries the local pastor, and Davis' Mrs Danvers-esque Dorothy is most displeased ... Original, bold and brilliant. Rebecca Nicholson Citizen Khan 10.20pm, BBC1 A new family-based sitcom starring Adil Ray as self-appointed community leader Mr Khan, previously a character in Radio 4's Down The Line and its underappreciated television offshoot Bellamy's People. This opener sees Khan struggle to keep face after forgetting to book the venue for his daughter's upcoming wedding, leading to conflict with well-meaning mosque manager Dave (Kris Marshall). Despite the occasional laboured gag, it's an affable enough debut, deserving a wider audience than this post-watershed slot is likely to attract. Mark Jones
