Tonight's TV highlights

Outcasts 9pm, BBC1 It's taken half a series, but Outcasts' heroic commitment to portentous dialogue and careful scene-setting is yielding results. Much like the Red Planet of Ray Bradbury's Martian Chronicles, Carpathia is revealing itself as a place where the past haunts the present. In other words – and this will make more sense after viewing tonight's episode – it's all about the ankle-biters, the golden retriever and the skeletons. Probably. Meanwhile, a raggle-taggle stranger shows up in Forthaven carrying tension-provoking diamonds . . . Excellent. Jonathan Wright When Teenage Meets Old Age 9pm, BBC2 The adage "respect your elders" is all but lost on the majority of teenagers, and the "elders" themselves believe the youth of today are obnoxious, undisciplined and impertinent. This new show attempts to bridge the generation gap, as young upstarts Jace, Johnny, Estenetia and Zoe are packed off to Whiteley Village care home to look after the residents for two weeks. They are soon bonding over a body wash or game of bowls, or jamming with a guitar and harmonica to Knockin' On Heaven's Door, in a show that's tender and touching, with humour that'll have you either creasing or cringing. Zachary Colbert Mrs Brown's Boys 10.35pm, BBC1 New, fourth-wall-smashing sitcom starring Dublin playwright Brendan O'Carroll as an interfering, gutter-mouthed mother- of-six – the TV version of a hilariously rude stage show. We're rarely more than 20 seconds from a "feck", or the more common Anglo-Saxon equivalent – although even the clean one-liners are often pretty wonderful ("When I was 18, I married his son, because of a condition I had called pregnancy"). Ali Catterall When God Spoke English – The Making Of The King James Bible 9pm, BBC4 It's 400 years since the King James Bible was first published. As writer Adam Nicolson's documentary makes clear, the creation of an official English translation was a mammoth task, undertaken by committees filled with bickering scholars. Not that you'd believe this from the glorious prose. The finished text, Nicolson argues, could only have been written by "the mind of England itself" – in part a way of saying that the King James version reconciled competing voices in an era when religion was at the epicentre of life. The programme is preceded by The Beauty of Books. JW Glee 9pm, E4 A virulent strain of "monkey flu from Borneo" takes Principal Figgins and Mr Schu out of action, leaving the school in the hands of Sue and substitute Holly Holliday, whom you may recognise as Goop proprietor Gwyneth Paltrow. This is no Britney-style stunt cameo – Gwyn rolls her sleeves up and gets fully involved, taking Cee-Lo's Forget You for a spin. And just when the prospect of Will doing baby talk threatens to undo all this good work, they pull a Journey joke out of the bag. Rebecca Nicholson Ross Kemp: Extreme World 9pm, Sky1 Chicago is the most racially and economically polarised city in America, with some 100,000 gang members and a heroin problem that stretches from the worst areas of the cities out to the suburbs, where young women are the largest new take up group. Venturing, as is his wont, into danger zones, Kemp interviews addicts living in organised communities on the edge of town, outreach workers and heavy-duty dealers. There are some insights but the Alan Partridge-like credits featuring Kemp striking thoughtful poses do the show no credit. David Stubbs
