TV Guide: Early Evening (5pm – 8pm)
Celebrity Bridge of Lies – BBC One, 5:40pm
Series 3, episode 2. Ross Kemp hosts, which continues to be an interesting casting choice that somehow works. Amy Dowden, Nina Wadia, Montell Douglas -- known to Gladiators viewers as Fire -- and Toyah Willcox are tonight's contestants crossing the lie-detecting bridge.
Celebrity Catchphrase – ITV1, 6pm
Stephen Mulhern is back, which is always a good sign. Guz Khan, Angela Scanlon, and Joel Corry are competing for £50,000 for charity. Say what you see.
Blankety Blank – BBC One, 6:25pm
Series 5, episode 3. Bradley Walsh runs the panel tonight, which includes Rhod Gilbert, Jill Scott, Aisling Bea, Guz Khan, Nitro, and Rev Kate Bottley. Guz Khan appearing on both Celebrity Catchphrase and Blankety Blank on the same Saturday evening is a scheduling coincidence worth noticing.
Secret Africa Into the Wild – Channel 4, 7pm
New series, episode 1 of 3. Explorer Lucy Shepherd sets off across Tanzania with a team of Indigenous hunter-gatherers. No crew, no safety net, no comforting production bubble -- just a camera and some of the most demanding terrain in East Africa. The stripped-back format gives it an unvarnished quality. This one is worth watching from the start.
Britain's Got Talent – ITV1, 7pm
Series 18, episode 7. The auditions wrap up in Blackpool tonight with £250,000 on offer for whoever makes it all the way to the end. If you've been watching from episode one, you'll have strong opinions by now. If you haven't, tonight's as good a place to start as any.
Elizabeth II The Unseen Photos – Channel 5, 7pm
What would have been Queen Elizabeth II's 100th birthday is marked tonight with a documentary built around rare and unpublished photographs -- candid images from private collections of someone whose entire existence was otherwise exhaustively documented. A companion piece, Philip and the Queen: A Royal Fairytale, follows at 8:30pm on the same channel. BBC Two is also running Elizabeth: The Unseen Queen at 6:35pm.
Michael McIntyre's Big Show – BBC One, 7pm
Series 5, episode 4 of 6. Lewis Capaldi is among the guests tonight. If you enjoy McIntyre's particular brand of high-energy warmth, this is your slot before the evening shifts into more serious territory.
TV Tonight: Prime Time (8pm onwards)
World's Most Secret Hotels – Channel 4, 8pm
The second series gets going with a globe-spanning first episode that starts in Bolivia, where a brutalist lodge sits over the largest salt flats on the planet. From there it moves to a futuristic mirror-clad resort in Norway, a bubble dome hideaway in County Fermanagh, and an art deco hotel perched in the Pyrenees. You will not be able to afford any of them. That is rather the point. The show works precisely because the destinations are so impractical as to feel like fiction -- and the filming makes them look even better than they have any right to.
The Weakest Link – BBC One, 8pm
Series 3, episode 7 of 14. Mel B, Eamonn Holmes, Shobna Gulati, Denis Lawson, Arielle Free, Briony May Williams, Nick Pickard, and Rob Bent are in the quiz chair tonight. The format does what it does.
Casualty – BBC One, 8:45pm
Series 46, episode 12 of 12 -- the series finale. See the full BBC One schedule for tonight. The episode opens at a funeral, with Stevie (Elinor Lawless) poised to deliver a eulogy. It's a disarmingly direct place to begin a finale, and the show uses it well: the opening immediately raises the question of who died and how, then cuts back two weeks to walk us through the events that led the team to the church. It's a structure that turns viewers into active participants rather than passive observers -- you're scanning every scene for clues, reading faces, second-guessing which decisions turned out to be the fatal ones.
Whether or not you've been following series 46 closely, this is television doing what it does best when it's working: using an ordinary genre format to get at something real about grief and consequence. Elinor Lawless has made Stevie one of the show's most compelling characters over the last few series, and this finale puts her right at the centre. Available on BBC iPlayer.
Black British Music at the BBC Volume 1 – BBC Two, 8:45pm
Trevor Nelson presents a 40-track archive celebration of black British music. An impressive selection from decades of BBC recordings. Followed later by Stormzy: Live at Glastonbury 2019 at 11:15pm -- more on that below.
Not Going Out – BBC One, 9:35pm
Series 14, episode 3 of 6. Lee has acquired a campervan. Lucy's reaction to the campervan is what this episode is about. If you know this show's rhythms, you already know how that is going to go.
TV Guide UK: Late Night
The Murder Line ⭐ – ITV1, 10pm & 11:10pm
This is the one. Oscar-nominated Minnie Driver -- fresh from Harlan Coben's Run Away -- turns up in a Canadian crime thriller that ITV1 is launching with a double bill tonight. The show goes by The Borderline in Canada, the title a reference to the 5,525-mile US-Canada border, the world's longest undefended frontier. Ontario cop Henry Roland (Stephen Amell) takes extraordinary risks to protect his old friend Tommy Hawley from a British criminal operation that has crossed the Atlantic looking for its missing cocaine shipment. Driver plays May Ferguson, the power-suited matriarch of that criminal organisation, and she is the reason to stay up. The series ran in Canada post-Super Bowl -- ITV1 airs two episodes tonight, with more tomorrow.
Dark, well-constructed, and full of the kind of plot turns that make you rewind to check you heard correctly. The six-part run has the bones of something that could hold its own against the best ITV1 crime drama of recent years. Don't miss this. Check the full ITV1 schedule or stream on ITVX.
The 1% Club – ITV1, 9pm
Series 5 premiere, episode 1. Lee Mack is back with the quiz that arranges its questions from easiest to hardest -- except the hardest ones aren't knowledge-based, they're logic puzzles that only one per cent of people can solve. A series premiere that should deliver the format at full energy.
Match of the Day – BBC One, 10:25pm
Five Premier League matches tonight, including the big one: Chelsea v Manchester United, with both clubs fighting for Champions League places. The highlights show will be structured around that fixture -- but get the full live experience on TNT Sports 1 from 7pm if you can. Available on BBC iPlayer.
Stormzy: Live at Glastonbury 2019 – BBC Two, 11:15pm
Seven years on and this still lands. When Stormzy took to the Pyramid Stage in 2019 as the first black British solo artist to headline it, the set he delivered felt like a statement and a party at the same time. Gospel choir, multiple costume changes, pyrotechnics, and a setlist that ran from grime to gospel without ever losing the thread. Late-night Saturday television doesn't get much better than this. Available on BBC iPlayer.
