There are a few powerful new series marking 20 years since the biggest terror attack on UK soil - this one is a three-part documentary that attempts to dig deeper into the "why?" As well as hearing devastating first-hand accounts from survivors and investigators, it opens by recalling the horrors of the day of the attack, alongside insight into how young men were being radicalised.

The final episode of the rebooted series centres on the lusotitan which, at 25 metres long, was one of the largest dinosaurs (and it's got the gangly neck to prove it). While not as impressive as it was in 1999, mixing CGI with real-life palaeontologists still leads to intriguing dino details. Hannah J Davies

"I just wish they wouldn't call it the tea time slot," 80-year-old Rod recently told the BBC. "That sounds like pipe and slippers." The crooner will try to prove them wrong as he takes to the Pyramid stage to deliver hits such as Do Ya Think I'm Sexy? and Maggie May.

DS Janie's mechanic is found murdered at a school reunion, in the series finale for the mismatched cop comedy-drama. Once again, Timothy Spall's retired actor uses Stanislavski methods to ferret out the truth, in a "consultant" role. Or as he puts it, "I'm very much here in a criminal psychologist capacity - don't mind me!" Ali Catterall

It's the penultimate episode of Margaret Atwood's not-too-dystopian drama and, while this final season has been frustratingly dragged out, we're still on the edge of our seats. After Aunt Lydia let June go ahead with Mayday, night has fallen and the Handmaids have dispersed on the streets of Gilead armed with razors.
Past Lives, 10pm, BBC Two
With Celine Song's new film Materialists on the brink of release, now is the perfect time to revisit the film that put her on the map. Past Lives is an extraordinary piece of work about a woman forced to re-examine her entire sense of self when an old love reappears, long after she has moved on. It's a film that aches with longing. It's knotty with the mess of cultural identity. All three of its leads do tremendous, heartbreaking work, but Greta Lee deserved an Oscar for her outstanding central performance. That she didn't even receive a nomination is utterly baffling. Nevertheless, consider this an update to Brief Encounter, only with a less infuriatingly paternalistic ending.
