Television choices: BBC3's dead clever drama In the Flesh is running wild

TV pick of the week: In the Flesh

Sunday 10pm & 1am BBC3

Slipping seamlessly into the Sunday-night BBC3 slot vacated last week by Being Human (RIP) is this equally inventive horror drama – a far more witty and original take on the zombie genre than Fox's feted but (in my opinion) monotonous The Walking Dead.

Luke Newberry plays Kieren, an un-dead teenager being re-integrated into his rural community under a new scheme introduced by a liberal government that sees zombies not as evil but as sick (their suffering labelled as PDS, or Partially Deceased Syndrome). But a local hate preacher (Kenneth Cranham in full Oranges Are Not the Only Fruit mode) disagrees, mobilising a militia, the Human Volunteer Force that includes Kieren's sister. Ricky Tomlinson and Steve Evets also stars.

Churchill and the Fascist Plot

Saturday 7pm Channel 4

How, in May 1940, Winston Churchill was facing the prospect of German invasion, but it wasn't just Hitler that concerned him. There was also the threat from Britain's own fascist sympathisers – and a few days after Churchill became prime minister, MI5 swooped on members of the Right Club, an extreme pro-Nazi society led by the anti- semitic MP Archibald Ramsay.

Can Eating Insects Save the World

Monday 9pm & 2.45am BBC4

The recent horsemeat scandal has exposed cultural sensitivities about what animals we will or won't eat, and in this film, Stefan Gates expands on his pet theory that eating insects could be the answer to future food shortages.

Anyway... live from homes across the nation, the psychologist Tanya Byron and a team of specialists help parents tackle their children's bedtime habits, aiming to get under-10s to sleep by 9pm.

Goodbye Television Centre

Friday 8.30pm BBC4

Michael Grade gathers former BBC luminaries – from David Attenborough, Ronnie Corbett and David Jason to Penelope Keith, Michael Parkinson and Fiona Bruce – for a final stroll down memory lane as the Corporation quits its west London headquarters for a final time, after 53 years' residence. Meanwhile, Victoria Coren takes a studio tour with Brian Blessed and Barry Cryer.

Horizon: How to Avoid Mistakes in Surgery

Thursday 9pm BBC2

"We are wired up to fail", says Dr Kevin Fong, as he explores research into removing as much human error as possible from surgical operations. His quest takes him from a casino, where he learns about 'cognitive load theory' (erm... I'll explain another time), to a flight simulator, where verbal checklists have drastically reduced pilot error.

Iraq: Did My Son Die in Vain?

Wednesday 9pm BBC2

A retired teacher from Wales, Geoff Dunsmore, visits the Iraqi city of Basra, where his RAF auxiliary son, Chris, was killed in a rocket attack in July 2007. Dunsmore's search for the truth about his son's death unwinds in tandem with his unfolding comprehension of the agony suffered by the Iraqis themselves during the British occupation and subsequent political vacuum.
