Bodyguard
9pm, BBC One
Arguably the finest practitioner of his craft currently writing for British TV, Jed Mercurio (Line of Duty) raises his game yet again with this six-part political thriller. It concerns a protection officer assigned to guard the home secretary, who may be the target of a terror plot following her support of a controversial new “snooper’s charter”. Trouble is, the bodyguard is an ex-soldier who resents the political masters who sent him to Afghanistan. Keeley Hawes and Richard Madden are outstanding as the leads. Continues tomorrow.

7pm, Channel 4

Hidden Britain By Drone
8pm, Channel 4
Tony Robinson’s latest cunning plan involves sending drones to shoot aerial footage of otherwise unobtainable sights. This intriguing series concludes with a look inside an active nuclear decommissioning site, as well as some revelatory up-close-and-personal film of bats on the wing. Phil Harrison
Eight Go Rallying: The Road to Saigon
9pm, BBC Two
Last time out, the Hillman Imp blew up and the Mini got rolled, so this week’s show is full of improvisation involving taxis and hire cars. On the way to ancient Khmer capital Angkor Wat, Tinchy Stryder displays his philosophical side, while Noel Edmonds somehow grows more smug than ever. MB
Krypton
9pm, E4
The cosmic prequel about Superman’s moody teen ancestor getting caught up in Kryptonian caste rivalries risks feeling so distant as to be irrelevant. Luckily, the inclusion of Adam Strange – a time-displaced wiseass from “our” Earth – makes things more relatable, and the politicking comes with a side order of kickboxing. Graeme Virtue
Ozzy & Jack’s American Roadtrip
9pm, History
Heading out on the road yet again, the Osbournes visit New Mexico. Here, they make “nuts” gags at the PistachioLand ranch, see the bleak beauty of the White Sands desert and hear a mariachi version of Paranoid. Plus Kelly joins the duo (“I’m being suffocated by misogyny!”). Jonathan Wright
Film choice
World War Z, 9pm, Channel 4
Max Brooks’s cult novel gets the blockbuster treatment from director Marc Forster. Brad Pitt is in full-on hero mode as a UN investigator zapping round the world in search of the origin of the zombie plague that’s laying waste to humanity. The zombies, fast-footed and swarming insect-like over all defences, are genuinely scary. Paul Howlett
