This episode of the celebrity genealogy show began with footage of Naomie Harris at Ian Fleming's former home in Jamaica, where she was helping launch Bond 25 (to be released next year), in which she is playing Moneypenny for the third time. It was a fitting location, as Harris’s folks hail from the Caribbean; her mother was born in Jamaica and her father's family are from Trinidad via Grenada.

Cindy Sherman predicted the selfie, so goes the claim. From our current standpoint, it is all too easy to analyse her many hundreds of photographic self-portraits made since the late 1970s as cultural forebears of the digital medium.

It was a year ago that BBC One scored a smash hit with the first series of Keeping Faith, but as series two opens 18 months have passed since Faith Howells’s husband Evan (Bradley Freegard) disappeared and triggered a traumatic chain reaction of events.

It’s a bold idea by director Dominic Savage, to create three improvised dramas for Channel 4 depicting women confronting different forms of crisis. To make it work he needed brave and powerful performers, and this first one starred Vicky McClure (the remaining two will feature Samantha Morton and Gemma Chan).

It was on 16 July 1969 that Apollo 11 lifted off from Florida en route for the Moon, and exactly 50 years later, as we nervously anticipate the dawn of commercial flights into space, the event resonates louder than ever. Here, Professor Brian Cox called it “the greatest achievement in the history of civilisation.” According to veteran broadcaster Sir Trevor McDonald, it was “the most magnificent thing that ever happened.”

Not everybody is on Facebook, yet. So far, Mark Zuckerberg’s social media monolith has only managed to scrape together about 2.3 billion users, roughly one-third of the planet. But as this fascinating documentary revealed, Facebook’s plans are huge and its ambitions boundless.

The Apollo 11 mission remains the most celebrated journey humanity has ever made. It produced some of our most iconic images, as well as the greatest speech gaffe, and a documentary of epic scale could be made that focused solely on the influence it has had on our popular culture.

“I want to discover how our government could fall apart and the country become bitterly divided in just a few weeks,” historian Lisa Hilton announced at the start of her BBC Four account of the traumatic demise of Charles I. In a mere 50 days in 1641-2, it seemed that the foundations of the state were sawn away as England tumbled towards a calamitous civil war.

Healthy, efficient and carbon-neutral, cycling ought to be a transport panacea. But in the dash for lycra, perhaps not enough attention has been paid to letting bikes and motor vehicles co-exist peacefully. This deliberately provocative Channel 5 documentary, which has sparked an angry backlash from within the cycling community, found plenty of ammunition from both sides.

It’s a topical idea, at least. Isaac Mensah, a child actor from a working-class family in London, has been cast in a Hollywood sci-fi blockbuster, and when he returns home his family and friends are agog to find out what his amazing movie experience was like. But the sky falls in when Isaac (Max Fincham) plays his parents a video he shot on his phone, containing evidence that he was abused by the film’s all-powerful producer, Jotham Starr, the boss of Yonder Starr Productions.
