Meet What You Eat
8pm, Channel 4
A show dedicated to revealing the secrets of the food industry, this week with an aquatic emphasis. How can you tell if a fish is fresh? Do chip shops really guard their batter recipes like state secrets? And how do you make the perfect homemade fish and chips? (According to this show, with a third of a bottle of prosecco – yippee!) Elsewhere, Michelin-starred chef Shaun Rankin cooks up steamed sea bass with lemon and asparagus. Ali Catterall
Medicine’s Big Breakthrough: Editing Your Genes – Panorama
8.30pm, BBC1
Reporter Fergus Walsh examines the future of medicine – specifically, gene editing, which promises astonishing advances in seeing off disease but also threatens complex ethical dilemmas as it becomes more possible for clever boffins to divert evolution itself. Gene editing has the potential to be literally life-changing, and not for the first time, science will challenge our wisdom to keep pace with our knowledge. Andrew Mueller
Handmade: By Royal Appointment
8.30pm, BBC4
A series focusing on brands that attain the royal seal. Wedgwood pottery makes items such as its jasperware panther vase using 200-year-old technologies, while, behind the scenes, trying to evolve its business strategy. It’s compelling to watch a vase being formed by the thrower, the turner, and the ornamenter, while hearing about how the brand is futureproofing by, as boss Ulrich says, “getting the dust away” from how the company name is perceived. John Robinson
Reg
9pm, BBC1
After Reg Keys lost his son Tom in Iraq, he discovered that the war itself had likely been unjustified, if not illegal. It led him to stand against Tony Blair in Sedgefield in the 2005 election in order to highlight the scandal. This true story provides the plot for Jimmy McGovern’s one-off drama starring Tim Roth as Reg and Anna Maxwell Martin as his wife, Sally. It explores extreme grief as it exists beneath the crushing shadow of culpable but unrepentant authority. Rachel Aroesti
Heathrow: Britain’s Busiest Airport
9pm, ITV
We want three things from airport docs: sparky characters in uniform, humiliating equipment malfunctions, and punters shouting because they’ve missed their flights. This series is too keen to advertise Heathrow’s efficiency to allow such levity. There are jetlagged alpacas and a man crying over a VAT refund, but mainly we’re building to the launch of BA’s new Dreamliner plane. Will there be last-minute snags? Let’s hope so. Jack Seale
Paul O’Grady’s 100 Years of Movie Musicals
9pm, More4
Via a mix of clips and talking heads, including James Corden, Sheila Hancock and Benny Andersson, comedian O’Grady traces the development of the big-screen musical. While you might question some of the editorial choices – more on the genius of Fred and Ginger would have been welcome – there’s still plenty to enjoy, not least O’Grady’s own affectionately catty contributions. On Natalie Wood being upset that Marni Nixon re-recorded her vocal parts as Maria in West Side Story: “That’s showbusiness, gerrover it.” Jonathan Wright
Game of Thrones
9pm, Sky Atlantic
Last week’s instalment was a classic table-setting episode, with pieces nudged gently into place in anticipation of something dramatic further down the line. This week, then, expect the banished Jaime Lannister heading to Riverrun for a clash with Blackfish Tully, Arya looking to beat a hasty retreat from Braavos, trailed by the Faceless Men, and the continuing integration of church and state in Kings Landing, which may well spell trouble for Cersei.

The Angels’ Share (Ken Loach, 2012) 11.25pm, Film4

There’s a touch of the wonderful Whisky Galore about Loach’s Cannes jury prize winner. It’s the story of young Glasgow chancer Robbie (Paul Brannigan, one of many non-professionals in the cast) and his dozy community-service mates; taken on a visit to a distillery by their kindly supervisor (John Henshaw), Robbie spots an opportunity for profit, and salvation, in the form of a rare single malt whisky that’s up for auction. Just as the title refers to the 2% of whisky that evaporates in the cask, they aim to make the precious liquid disappear. Paul Howlett
Outbreak (Wolfgang Petersen, 1995) 10.50pm, TCM
Dustin Hoffman’s army medic tries to contain a deadly, Ebola-type virus that arrives in California from Africa. Sinister general Donald Sutherland has a different agenda, and although the film switches into predictable action mode, with Hoffman an unlikely Rambo type, the smart cast – including Rene Russo, Morgan Freeman and Kevin Spacey – keeps it very watchable.
