Amazing Spaces Shed Of The Year
8pm, Channel 4
If it’s a wacky series about garden sheds, it can only be Channel 4 – but this show has unearthed some remarkable constructions, whose eccentricity speaks volumes about the UK. Tonight, it’s the Workshops and Studios category, and those competing for advancement include the owner of a lawnmower museum, an avid anvil collector, an artist inspired by the arte povera movement and a Star Wars fan with a shed to match.

Highlands: Scotland’s Wild Heart
9pm, BBC2
Scotland’s dramatic scenery occasions this trip through its “wild heart”, in which cameras soar over ruggedly breathtaking landscapes with a Ewan McGregor voiceover. Tonight: summer, and a look at parenting habits. A visit to the Handa Cliffs in the northern Highlands finds adorable, clumsy pairs of guillemots, whose eggs are preyed upon by bigger, sneakier herring gulls. A hundred miles south, single mothers teach otters to fish. John Robinson
8 Out Of 10 Cats Does Countdown
9pm, Channel 4
Jimmy Carr hosts another helping of humorous word wrestling, with regular team captains Jon Richardson and Sean Lock joined by David Mitchell and Katherine Ryan. Rachel Riley remains on number and letter duty, while Susie Dent shuffles along her Dictionary Corner bench to make room for guest dictionary delvers and YouTube popmakers the Brett Domino Trio. And, believe it or not, that name is not an anagram. Mark Gibbings-Jones
The Out-Laws
9pm, More4
A slow burner, but also one of the best Walter Presents offerings to date, this dark Belgian dramedy about four sisters plotting to kill their vile brother-in-law reaches a key moment when Jean-Claude’s body is exhumed. Meantime, in flashback scenes, we learn that Jean-Claude wasn’t much interested in sex with his wife. Instead, he preferred to channel his energies into competing for a promotion at work, targeting potential rivals with obnoxious pranks. Jonathan Wright
X: The Generation That Changed the World
9pm, National Geographic
No deep insight this week from the US nostalgia doc: geeks used to be mere runts, but a process that began with Star Trek and ended with Google saw them reinvent humanity. Mobile phones, Pong, samplers and Apple’s still-astonishing 1984 Super Bowl ad flash past in a shallow but enjoyable parade of retro images. At the close, there’s a brief pause to wonder whether computers will now kill us all. Jack Seale
Friday Night Dinner
10pm, Channel 4
Robert Popper’s family sitcom has become something of a fixture. It probably writes itself by now, but for all its occasional predictability it remains effortlessly amusing, mainly thanks to the cast’s enviable chemistry. Tonight, Adam feebly regresses back to childhood after tonsillitis. But how long can Johnny bear his brother’s coddled antics? A trip to Grandma’s house is the trigger for the familiar fraternal jousting. Phil Harrison
It’s Not Me, It’s You
10pm, Channel 5
Eamonn Holmes is released from daytime TV to embrace his cheeky side on this panel show about the perils of dating. Perennial pin-up Kelly Brook and Vicky Pattison, who made her name on Geordie Shore but is crafting herself a fine career as a TV personality, are captains. Sharply scripted one-liners keep things on the right side of Celebrity Juice-style crassness, but few gags are off-limits, so expect plenty of mother-in-law and Tinder-based laughs. Hannah Verdier
Film choice
A Fish Called Wanda (Charles Crichton, 1988) 10.40pm, ITV
Never a dull moment in Charles Crichton’s lovely Ealing-esque comedy. A gallery of rogues includes barrister Archie (John Cleese) – who falls for gangster’s moll Wanda (Jamie Lee Curtis) – stooge Michael Palin and, most of all, Kevin Kline as Wanda’s psychotic boyfriend, Otto: he wants his jewels back, and he’ll eat goldfish to get them. Paul Howlett
Flying Blind (Katarzyna Klimkiewicz, 2012) 11.10pm, BBC2
Helen McCrory has attracted richly deserved praise recently for her matriarchal role in TV’s Peaky Blinders and her smouldering stage performance in The Deep Blue Sea. She is also the highlight of Katarzyna Klimkiewicz’s implausible thriller: her Bristol-based engineering lecturer, Frankie, falls for handsome student Kahil (Najib Oudghiri), who, apart from the rampant sex, is suspiciously interested in her drone-design expertise.

Olympic choice
Remember when Jessica Ennis-Hill won both gold and our hearts to the soundtrack of Bowie’s Heroes? Those were the days. Perhaps new mum Jessica can provide some needed optimism as she begins her defence of the heptathlon title (1.35pm, BBC2). Later in the evening, Team GB aims for gold in the equestrian dressage (7pm, BBC1) and Bradley Wiggins leads the cycling men’s team in the first round of the pursuit (8.50pm, BBC1). Amy Walker
