Nine Bodies in a Mexican Morgue
9.20pm, BBC One
The American authorities are in Mexico demanding answers about Flight CBZ517: was the aircraft even legit?

Romesh Ranganathan’s Parents’ Evening
9.35pm, ITV1

Her son’s name may be in the title but it’s Shanthi Ranganathan who is the MVP of this comedy game, often upstaging Romesh as she tallies the scores. This week’s parent-child teams being quizzed are Alex Brooker and his mum Elaine, Jeff Brazier and his son Bobby, and perhaps the ultimate glam fam: Janet Ellis and Sophie Ellis-Bextor. Graeme Virtue
The Intruder
9.45pm, BBC Four
It’s the second and concluding double bill of the moreish French psychological thriller about a shifty au pair. Paula has been arrested for neighbour Aline’s murder – and the fact Paula was having an affair with Aline’s husband isn’t great. But she’s adamant that Tess – who is still looking after her children in her home – is the real perpetrator. HR

The Twits, out now, Netflix

The first animated feature born out of Netflix’s purchase of Roald Dahl’s back catalogue takes the book’s cruel, disgusting, prank-playing couple and sets them against a bunch of resourceful American kids. Margo Martindale and Johnny Vegas voice Mr and Mrs Twit, whose dream of opening a theme park falls foul of Maitreyi Ramakrishnan’s Beesha, doyenne of the local orphanage. There is plenty of burping and farting – and the odd exploding bottom – to remind you of Dahl’s penchant for earthy physical comedy, before the hugs and learning kick in. Simon Wardell
The Menu, 9pm, Channel 4
Revenge is a dish best served with a potato confit and beef jus. Luckily, chef Julian Slowik (a steely Ralph Fiennes) is a feted master of fine dining. Unluckily, the 12 guests chosen to join him for a meal on his private island all have dark deeds in their pasts for which Slowik will punish them. Anya Taylor-Joy plays the cuckoo in the nest, Margot, who is the date of idiot gourmand Tyler (Nicholas Hoult) but is not what she appears. Mark Mylod’s darkly comic drama is an exquisite concoction – from the artful food to the escalating fear as the diners see what the next course brings. SW
