In 1975, Sky captivated TV audiences. Created by Doctor Who writers Bob Baker and Dave Martin, the ITV series followed a time-travelling alien stranded on Earth and the children he befriended. Fifty years later, Sky returns, as a full-cast audio drama. 

In Sky, Before the Chaos, a box set of three brand-new episodes written and directed by Gary Russell, Sky (Cloud Quinn) arrives once more in the town of Stanton Cheyney, where his old friend Arby Vennor (Edwin Flay) now resides in a nursing home. 

Together with new allies – Bex Briggs (Jessica Hayles), Kyle Brannock (Samuel Morgan-Davies), and investigate journalist Jack Diver (Conrad Westmaas) – Sky and Arby discover that, from a malevolent natural force to a sinister tech corporation, the balance of life on Earth faces greater threat than ever. 

Sky: Before the Chaos is now available to purchase as a digital download to own for just £19.99, exclusively here. 

The three full-cast audio episodes are: 

Apotheose 

Two teenagers, the executive of Youngwell Corporation, a discredited journalist and an old man in a nursing home are brought together when a mysterious voice calls from within an ancient burial mound in the heart of Stanton Cheyney. The crows are flying, the public are chanting, and something malevolent is about to make itself known… 

Deitropism 

Sky is reunited with old friends and is now a TV superstar. A spy has infiltrated Youngwell Corporation and Jack Diver is trying to uncover secrets. Someone has a secret wrapped inside their genes and someone else is going to discover that the trees are not quite what they seem… 

Calyx 

As the survivors of mankind struggle to live beneath the biomass of plant life that literally envelops the planet, cutting off the sunlight and the air, an old enemy of Sky’s finally manifests, determined to make things worse.  As the hunt for the Juganet becomes more and more desperate, Bex Briggs discovers that one should never stand still for too long in this terrifying new world order… 

Lead actor Cloud Quinn takes over the role played by Marc Harrison in the original TV series. He said: “Sky definitely piqued my interest. I watched a little on YouTube and I read the novel of the original 1970 series, and I just loved the imagination of it. 

“It felt very challenging for children, but in a good way, opening their horizons to the big issues of the day around space flight and nuclear power and continuous industrialisation, and what that meant for the natural world – obviously that remains very, very relevant today.” 

Edwin Flay, who plays Arby Vennor, added: “The audio revival is very well crafted in that you don’t need to have seen the original, but it grows from it, it feeds on it, and it brings all of the concerns very much up to date. The way our two characters have evolved from the original series and the journeys they’ve been on in the interim give it a lot of its meat for me, certainly. 

“In the original series, Arby Vennor was young, vibrant, and kind – a very straightforward, uncomplicated character – and now his experience has left him a broken shell. Exploring that, as he finds his drive and his sense of self again, has been a pleasure.”
