New TV shows in 2021 on NOW TV and Sky

Your Honor

Coming soon to Sky Atlantic with NOW TV

It stars Bryan Cranston. It’s a ten-part morally murky thriller. It’s created by the producers behind The Night Of and The Good Wife. If you’re not excited by Your Honor, get someone to check your pulse.

In his first TV lead since Breaking Bad, Cranston plays a respected judge who tries to protect his son after he becomes involved in a hit-and-run, believing he can keep him safe if he tells no one.

A high-stakes game of lies, deceit and impossible choices, check out the nail-biting trailer to get a flavour of what’s to come.


Coming in 2021 to Sky Atlantic with NOW TV

Inspired by real events, the drama explores the lives of convicted killers Susan (Olivia Colman) and Christopher Edwards and asks how this devoted and mild-mannered couple came to kill Susan’s parents and bury them in the back garden of their Mansfield home, in a crime that remained undiscovered for over a decade.

Blackly comic and taking viewers into the surreal fantasy world that Susan and Christopher created for themselves, this promises to be a dark murder story quite unlike any we’ve watched before.


Coming in Spring 2021 to Sky One with NOW TV

Starring Eleanor Tomlinson (Poldark), Savannah Steyn (The Tunnel), Thomas Turgoose (This Is England), Sharon Duncan-Brewster (Sex Education), Natasha O’Keeffe (Peaky Blinders), Craig Parkinson (Line of Duty) and Oliver Coopersmith (Tin Star), Intergalactic is an ambitious and emotional new sci-fi series coming this Spring.

All she has to do is kill her husband (Nicholas Hoult), beat the church, baffle the military and get the court onside.

The Pembrokeshire Murders

Airs on ITV on 11th, 12th and 13th January at 9pm


Hollywood star Luke Evans delivers an incredible performance in this three-part true story of a serial killer and the incredible Detective Superintendent Steve Wilkins.

In 2006 Wilkins (Evans) reopened two unsolved double murder cases that had cast a shadow over the Dyfed Powys police force since the 1980s and through a combination of forensic science, sheer determination and, remarkably, footage of the ITV gameshow Bullseye, they were able to suddenly make inroads into the case.

The Pembrokeshire Murders is a stranger-than-fiction story that acts as a tribute to the power of humour endeavour and showcase one of the most extraordinary cold cases.


John Simm, Richie Campbell and Rakie Ayola star in ITV’s highly-anticipated adaptation of Peter James bestselling novels about Detective Superintendent Roy Grace.

Filmed in Brighton and the South Coast, the series will bring to life the addictive page-turners and twist-filled stories that have gripped millions.

Adapted by Russell Lewis (Morse, Kavanagh QC), we can expect the series to rank among the very best detective dramas.
