Lord of the Flies
9pm, BBC One
Remarkably, this is the first TV adaptation of William Golding’s classic novel. Who better to handle such responsibility than Jack Thorne? He takes a faithful approach to the story in an epic four-parter, which has the support of Golding’s family. It follows a group of schoolboys who, while fleeing from a war during the 1950s, have crash-landed on a Pacific island. All the adults are dead and the boys must make decisions on how to survive and be rescued. Each episode comes from the perspective of one of the core four – Ralph, Piggy, Simon and Jack – with Piggy taking the opener. It’s beautifully shot on location in Malaysia and wonderfully performed by a cast of more than 30 young actors. Hollie Richardson
