La Brea
10pm, Channel 5
Executive-produced by, among others, David Applebaum, one of the writers and producers of The Mentalist, here’s an ambitious sci-fi disaster drama about a humongous sinkhole that pulls people and buildings into its depths in Los Angeles. While the rest of the world tries to work out what just gobbled up half a city, those inside it need to navigate its inexplicable primeval land – and each other. The full season will be available to stream on Paramount+ after this debut episode. Hollie Richardson
MasterChef Australia
7pm, W
The Aussie take on MasterChef is a good deal more showbiz than the UK version – whoops and high fives proliferate. It also feels more stretched: in tonight’s opening episode, nearly 20 minutes pass before any cooking happens. Once we get going, it’s the usual foodie’s treat, as new contestants are put up against returning stars from previous seasons. Phil Harrison
Westworld
9pm, Sky Atlantic
Even with this season’s revitalising plot twists, Westworld is still most electrifying when it allows its actors to face off. Tonight, Charlotte (Tessa Thompson) torments a confused Caleb (Aaron Paul) over the whereabouts of his daughter. Meanwhile his grownup daughter C (Aurora Perrineau) tries to suss out the motivations of Bernard (Jeffrey Wright). Henry Wong

Big Zuu’s Big Eats
10pm, Dave
