Prepare for blood and guts galore in Crystal Lake. Plus: David Harewood’s great legal drama, Pierre. Here’s what to watch this evening

9pm, Sky Atlantic
A Friday the 13th prequel series produced by A24? Halloween has come early for gorefest fans. Linda Cardellini plays small-town single mother Pam Voorhees, who takes her son Jason (Callum Vinson) to summer camp where she works as a cook. But one day Jason drowns in the lake. Fast forward a year, and Pam is grieving but clings to a shred of hope as her son’s body still hasn’t been found. When two cops knock on her door to tell her they have discovered Jason’s remains, things take a huge turn – and it turns out there’s more to her and Jason’s story than meets the eye … It has all the jump-scare beats of a classic 70s slasher movie and Cardellini gets stuck in – blood, guts and all.
