She asks him not to tell his loving but despairing father (Tom Davis) – the vampire king! Can poor Valentine pull off being the heir to the vampire throne? Neil and Rob Gibbons – the team behind Alan Partridge – have done a fun job of adapting Eric Morecambe's much-loved children's book.

Star Trek: Strange New Worlds

In the year of Star Trek's 60th anniversary, it's pleasing that this vibrant streaming hit – a direct prequel to the original series – is getting beamed down to terrestrial TV.

The Deb, 6.15am, 5.45pm, Sky Cinema Premiere
Rebel Wilson's directorial debut is the subject of long-running legal disputes but you wouldn't know it from watching this sweet, simple musical comedy. It's set up as a city v country clash: rebellious Sydney teenager Maeve (Charlotte MacInnes) is banished to the bush to stay with farming cousin Taylah (Natalie Abbott) in "the town where feminism has come to die" – and where the debutante ball is still a thing. Issues of body positivity and stifled ambition are showcased in songs with a certain Aussie pep (the first one is titled Fuck My Life).
The Order, 10pm, BBC Two
Jude Law adds to his recent run of interesting character choices (Putin, Henry VIII, a Star Wars villain) in Justin Kurzel's gripping fact-based crime thriller. He plays FBI agent Terry Husk, whose new posting to rural Idaho comes with an Aryan Nation splinter group, led by Nicholas Hoult's charismatic Robert Jay Mathews, who are progressing from counterfeiting and bank robbery to something much bigger. Law's Husk is a convincingly raddled near has-been but he's a dog with a bone when he gets a sniff of Mathews's racist plot.
The Crime Is Mine, 12.50am, BBC Two

However, aided by her flatmate, lawyer Pauline (Rebecca Marder), she plans to confess to "legitimate defence", hoping the publicity will be good for both their careers. That is, until Isabelle Huppert's wrecking ball of a silent film star pops up.
