TV tonight: the must-see new drama for Marian Keyes fans

The bestselling novelist brings her beloved Walsh sisters to the screen. Plus: Patrick Dempsey lets loose with Jonathan Ross. Here’s what to watch this evening

The Walsh Sisters

Sat, 9.15pm, BBC One

Finally, Marian “Queen of the Romcom” Keyes is bringing her flawed, hilarious and painfully relatable characters to the small screen. It starts with Rachel being forced into facing her relationship with alcohol – but does she really think she has a problem? Meanwhile, outgoing single mum Claire is finalising her divorce. Heart-tugging and thoughtful, with that cracking Irish comedy laced throughout. Hollie Richardson

Sailing the Shipping Forecast With the Rev Richard Coles

6.15pm, Channel 4

The Rev finds the shipping forecast so soothing that he considers it a sort of prayer. For the penultimate leg of his lovely journey marking the radio broadcast’s centenary, he’s exploring the area of Wight, a stretch of the Channel. He starts on the Isle of Wight where the annual regatta is taking place in Cowes, before training up for seven-star service at a superyacht school. HR

Michael McIntyre’s Big Show

8.15pm, BBC One

B*Witched are pranked in Unexpected Star; Shane Richie and Gillian Taylforth contribute to a special EastEnders-themed TV Takeover; and Peter Crouch and Abbey Clancy are the first ever couple on Remember Me. They may or may not recall who sang at their wedding … but someone definitely remembers their secondary school crush. Ali Catterall

Roman Empire By Train With Alice Roberts

8.15pm, Channel 4

The latest archaeological odyssey with Prof Roberts stops off, inevitably, in Rome and she seems delighted to explore such a richly historic city. Then she hops on a bike for a bone-rattling detour on the Appian Way, the ancient but durable road that helped a voracious empire expand. Graeme Virtue

The Jonathan Ross Show

9.25pm, ITV1

One for Grey’s Anatomy fans: Patrick Dempsey is plugging his new thriller Memory of a Killer in Ross’s studio this week. They’re joined by Jack Whitehall, last seen having a hoot as a bad nanny in last year’s Malice, and Self Esteem – AKA Rebecca Lucy Taylor – who is currently on the West End stage in a revival of Teeth’n’Smiles. HR

Dinosaur

10pm, BBC Three

In this series-closing double bill of the brilliant Glasgow sitcom, a museum open day brings the love triangle to a sharp point and there’s further iniquity from antiquities (“Grave robbing and boyfriend robbing?!” says Evie). Then some advice from her lovely colleague Declan sends Nina on a dash to declare her feelings. Ellen E Jones

Film choice

The Fabelmans, 9.15pm, Channel 4

Steven Spielberg mines his own history for his most personal film yet, a 1950s-set drama about family, growing up and the power of cinema. It follows Sammy Fabelman (played by Gabriel LaBelle as a teenager), who becomes obsessed with movie-making at a young age and persists with his celluloid dream as the family relocate from New Jersey to Arizona to California. Although there is nostalgia for the postwar age of opportunity, there is antisemitism, too – and domestic turbulence between his very different parents (Michelle Williams and Paul Dano).
