TV highlights 05/08/2011

Superheroes of Suburbia 7.35pm, Channel 4 It's doubtful that Lois Lane or Mary Jane ever waved off Superman or Spider-Man with the words "Bye, be safe, don't do anything I wouldn't do", as wife Julie does for her husband The Dark Spartan, aka 27-year-old Will from Torquay. Like the others in this fabulously quirky documentary, Will takes his costumed superhero duties entirely seriously – despite the fact that he has yet to stop any crime. There is darkness and melancholy here, rumbling quietly below the surface, but it never threatens to unbalance Christian Watt's funny, original and very English film. Superb. Ali Catterall Someone's Daughter, Someone's Son 9pm, ITV1 Just because a documentary is hard-hitting (such as the fly-on-the wall Strangeways earlier this year) doesn't necessarily make it insightful or informative. However, this new series, focusing on the impact of violent crime on victims' families, looks as if it may be. The murder of nurse Jane Clough was devastating for her family. What torments them still is that the murderer, Jonathan Vass, was at the time free on bail, having been charged with Jane's rape. This follows her parents as they campaign for a change in the bail system. John Robinson BBC Proms 2011: Human Planet Prom 7.30pm, BBC4 A minor self-indulgence on the BBC's part. The BBC Concert Orchestra, conducted by Charles Hazlewood, perform Nitin Sawhney's soundtrack scores from the BBC's Human Planet, while big screens play scenes from the series. The concert also acknowledges musicians who appeared in Human Planet, including Greenland's Rasmus Lyberth, Zambia's Enock Mbongwe, Mongolia's Khusugtun, and the Bibilang Shark-Calling Group from Papua New Guinea. It features interviews with the musicians, and behind-the-scenes footage. Explorer Paul Rose is an apposite presenter. Andrew Mueller America's Got Talent 9pm, ITV2 America's Got Talent comes to an end tonight, somewhat overshadowed by the imminent arrival of The X Factor USA and right-on sing-along The Voice. There have been plenty of impressively OTT performers vying to perform in Las Vegas, from motorcycling troupe the Smage Brothers to Miss Lynne's shadow-dancers, Silhouettes, but here's hoping pole dancer Steve Retchless makes it all the way, if only to see the devastated look on Piers Morgan's face. Sian Rowe Big Love 9pm, Sky Atlantic The start of the third season means another wife for polygamous Mormon Bill Henderson. Ana, the waitress he met last season, seems the best candidate, so Barb, spurred on by her cancer, decides to confront her about her intentions. You'd think having multiple wives would make Bill the envy of the neighbourhood, but local gossips make the going tough, so they throw a party to show everyone that they are just regular folk. Things don't go according to plan, but it does give Chloë Sevigny a chance to shine. Phelim O'Neill Alan Carr: Chatty Man; The Rob Brydon Show 9.30pm, Channel 4; 10pm, BBC2 Alan Carr has clearly earmarked this final episode of Chatty Man as the one that will grant him chatshow supremacy in the golden Friday night post-watershed slot. His line-up includes Justin Timberlake, Mila Kunis and Jessie J. Poor Rob Brydon struggles gamely to compete but, with due deference to Sophie Ellis-Bextor and Bruce Forsyth, he doesn't quite have the same star quality. Gwilym Mumford
