Blue Planet II
8pm, BBC One
Tonight’s episode of this luxuriant homage to the world beneath the water focuses on coasts – and on the creatures at home in the oceans, on land and in the puddles in between. Sir David Attenborough narrates the extraordinary footage gathered once again by the BBC’s Natural History Unit, including glorious depictions of sea turtles, king penguins, puffins, eels and octopus. The Galápagos sea lion hunting yellowfin tuna is worthy of a Bond film. Andrew Mueller
Coastal Railways With Julie Walters
8pm, Channel 4
Walters is good company in this cheerily bog-standard travelogue, genuinely enthused by the “local person with unusual job” segments, and displaying a gift for ad libs that you might mistake for lines written by Victoria Wood. The trip from Newcastle upon Tyne up the east coast takes in the restored Alnwick branch line, an EE Cummings recitation in Berwick-upon-Tweed, a lobster nursery in north Berwick and a secret tunnel in Edinburgh. Jack Seale
Howards End
9pm, BBC One
The sumptuous period drama concludes, with Margaret soon consumed with worry over sister Helen, now incommunicado in Europe following the awkward meeting between the Basts and Henry at Evie’s wedding, and the revelation that Henry and Jacky had once engaged in an affair. While Margaret makes every effort to forgive Henry, the fate of the Schlegel sisters appears to be inexorably drawn to Howards End, but there will be tragedy before the reconciliation. Ben Arnold
Expedition Volcano
9pm, BBC Two
The Nyamuragira volcano lies at the heart of the Democratic Republic of the Congo – a troubled and impoverished region even without the looming presence of a huge, unpredictable, destructive force. The final part of this series sees Professor Chris Jackson and his team visit the area to both investigate the volcano and talk to the locals about how, for better or worse, living in Nyamuragira’s shadow affects every aspect of their lives. Phil Harrison
Snowfall
10pm, BBC Two
If you’ve made it through the highs and lows of this patchy first season, it’s time to claim your reward. This double-bill finale of John Singleton’s 1980s, LA-set cocaine trade drama sees some genuinely surprising plot twists, as Franklin acts the cool-headed kingpin (Peckham lad Damson Idris shines, as always), Lucia lays her father to rest in untraditional style, and that crack stuff proves rather moreish. All of it bodes well for a superior second season. Ellen E Jones
Babylon Berlin
9pm, Sky Atlantic
The second season of this series set in 1920s, pre-Nazi Berlin kicks off with a double bill. Rath, transferred from Cologne, is looking to assemble a team to investigate a multiple homicide but is uncertain about Charlotte. Meanwhile, a family visit from Cologne sees him reunited with his sister-in-law and nephew. The ominous redolence of the era is brought vividly to the screen; surreal touches include Bryan Ferry guesting as a cabaret crooner. David Stubbs
The Lowe Files
10pm, History
Is Rob Lowe secretly addicted to Most Haunted? It feels as if the only explanation for this deeply strange reality show, in which The West Wing’s vampire dreamboat and his two college-age sons use family bonding time to investigate spooky places. Their first stop is Preston Castle, an old Californian reformatory school for boys that is notorious for housing vengeful spirits. This leads to late-night Lowe jitters captured in sickly green night-vision. Graeme Virtue
TV films
Taxi Tehran (Jafar Panahi, 2015), Sunday, 11pm, BBC Four
Banned from making films for 20 years, dissident Iranian director Jafar Panahi has bravely continued his trade through imaginative guerrilla film-making, most recently with this Berlin Golden Bear-winning “road movie”. It’s a simple setup: Panahi installing video cameras in a taxi, then taking to the streets to record his passengers talking about their lives and opinions. With a black market DVD seller, Panahi’s niece and a human rights lawyer on board, a witty and highly amusing impromptu critique of Iran’s authorities unfolds. Paul Howlett
Nacho Libre, (Jared Hess, 2006), 7.05pm, ITV4
Jack Black is Ignacio, a paunchy friar who cooks the horrible gruel for the children at a Mexican orphanage. But, Zorro-like, he becomes the masked wrestler Nacho Libre, fighting for better food, and to win sexy Sister Encarnación (Ana de la Reguera). It’s an eccentric comic knockout. Paul Howlett
Mission: Impossible – Ghost Protocol, (Brad Bird, 2011), 9pm, Channel 4
Tom Cruise pits his Impossible Missions team against terrorist Michael Nyqvist, who plans a nuclear armageddon. It’s the same old stuff, but Brad Bird (director of The Incredibles) excels in the action sequences, from Hunt’s Russian prison breakout to a stunning scene up Dubai’s Burj Khalifa skyscraper. Paul Howlett
Gunga Din, (George Stevens, 1939), 1.45am, Movies4Men
This vintage Rudyard Kipling adventure has the wonderful writing team of Ben Hecht and Charles MacArthur fleshing out the imperialist poem. Leading the heroics is a top-notch trio – Cary Grant, Victor McLaglen and Douglas Fairbanks Jr – playing soldiers of fortune much in the spirit of Caine and Connery in The Man Who Would Be King. Sam Jaffe is Gunga Din, the self-sacrificing waterbearer who saves the day. Paul Howlett
