Carry On Caravanning
8pm, Channel 5
This is billed as a lighthearted documentary featuring some of the nation’s one million caravan owners. No previews were available, but the phrase “lighthearted” conjures the usual plucked-strings accompaniment and knowing voiceover that are usually tacked on to this kind of show. And the emphasis will also, no doubt, be on the eccentric as the film-maker rides shotgun with various enthusiasts to find out why they love their mobile homes so. At least one clip from Carry On Camping must be shown by law. Julia Raeside
Storyville: Circus Elephant Rampage
9pm, BBC4
This grimly compelling film tells the story of Tyke, an African circus elephant who died in a hail of bullets in 1994 after going rogue, trampling her handler to death and rampaging through Honolulu. The footage of the incident is horrifying enough; what’s worse is the context. Despite the best intentions of most handlers, circus animals are often mistreated and the notion of a special relationship between man and beast is frequently mere window dressing for exploitation and cruelty. Phil Harrison
Erotic Adventures Of Anaïs Nin
9pm, Sky Arts
“That afternoon in Henry’s room was like a white-hot furnace.” Shivani Kapur and Broadchurch’s Lucy Cohu play author Anaïs Nin in these re-enactments from her diaries, interwoven with ruminations from the likes of the Erotic Review’s Rowan Pelling. While the dramatisations are all teasing, nipple-flashing, Vaseline-lensed affairs, the writing remains as revolutionary, powerful and seductive as ever (“I want to bite into life and to be torn by it”); this is a celebration of Nin as a literary marvel, first and foremost. Ali Catterall
Life On Marbs
9pm, ITVBe
Naturally, the makers of Towie have chosen Marbella – the Essex crew’s holiday hotspot – as the setting for this new “reality” series following minted expats. Among the cast are 34-year-old retiree Jon, permatanned promoter Jeff, nightclub boss Lina, and Natalie, a cosmetic surgery fan who dubs herself the “Marbie Barbie”. There’s even a guy who washes his watches in Cristal, proving that money can’t buy you brain cells. Straddling the line between binge-worthy and bin-worthy, could this be so bad that it’s great? Hannah J Davies
Witnesses
10pm, Channel 4
The opening scenes in this French thriller could hardly be more unsettling, as cops pore over a crime scene that involves a trio of recently exhumed corpses – a man, a woman and a teenager – posed in a show home. Why has this been done? And why has someone placed a photo of retired cop Paul Maisonneuve (Thierry Lhermitte) in the bedroom? Detective Sandra Winckler (Marie Dompnier) would certainly like to know. If Spiral is France’s The Wire, this may be its Broadchurch. Both chilling and compelling. Jonathan Wright
Wentworth Prison
10pm, Channel 5
Season three of the Prisoner Cell Block H reboot. Bea (Danielle Cormack) is back, doing life without parole for killing the gangster who murdered her daughter, so she has nothing to lose in her war with twitching, vinegar-breathed governor Ferguson (Pamela Rabe). The scenes where they and other sworn enemies camply eyeball each other would be hilarious if the show weren’t so suffocatingly grim: its vision of screws and inmates dedicated to manipulating and injuring each other is surprisingly well made but hard to enjoy. Jack Seale
Cashing In
10.35pm, BBC1
From decluttering to parting with possessions for financial reasons, there are myriad reasons for visiting a high-street secondhand retailer such as Cash Converters. This new series considers the patrons and personnel of two of the chain’s stores, examining life among the racks of used guitars and copies of Fifa 11. In this opener, Glasgow manager Harry Harrison formulates a strategy to generate an upturn in sales, while on the other side of the counter a family find themselves needing a quick intake of cash for funeral expenses.

Lonely Are The Brave
(David Miller, 1962) 11.20am, More4
A thoughtful, affecting contemporary western with Kirk Douglas in fine, unusually subtleform as an old-fashioned outlaw: a lone horseman pursued by sympathetic sheriff Walter Matthau’s helicopters and jeeps. The formerly blacklisted Dalton Trumbo’s script is an elegy to a vanished time, while Philip Lathrop’s stark monochrome photography is bleakly stunning. Paul Howlett
Blackfish
(Gabriela Cowperthwaite, 2013) 9.55pm, BBC4
Killer whales are pretty relaxed about humans in the wild. But stick them in a marine park pool and train them to do daft stuff for people’s amusement, and they start to change into homicidal beasts – ie, proper killer whales. That’s the drift of this fascinating and really suspenseful documentary. PH
