A Discovery of Witches will air on Friday 14th September at 9pm exclusively on Sky One and NOW TV

Adapted from Deborah Harkness's bestselling All Souls trilogy, A Discovery of Witches is a modern-day love story, set in a world where witches, vampires and daemons secretly live and work alongside humans, hidden in plain sight.

The Sky original production stars Teresa Palmer (Hacksaw Ridge) as academic and historian Diana Bishop, a witch denying her magical heritage. Until the discovery of an ancient manuscript in Oxford's Bodleian Library throws her into the heart of a dangerous mystery - and into the path of enigmatic geneticist and vampire Matthew Clairmont, (Matthew Goode - Downton Abbey, The Crown), who hides a dark family secret.

As Diana and Matthew embark on a journey to find the secrets of the manuscript and their relationship develops, events threaten to unravel the fragile peace between the creatures, a peace overseen by the Congregation, a shadowy institution of powerful vampires, witches and daemons.

Alex Kingston plays Diana's aunt, Sarah Bishop, a practising witch and coven member. Owen Teale is Peter Knox, a powerful witch and leading Congregation member. And Louise Brealey plays Gillian Chamberlain, a witch and professor at Oxford University.

Made by Bad Wolf Productions, A Discovery of Witches has been adapted for screen by writer Kate Brooke (Mr Selfridge), who is also an executive producer. The co-founders of Bad Wolf, Jane Tranter and Julie Gardner, and Lachlan MacKinnon are executive producers along with Deborah Harkness. Juan Carlos Medina (Painless) is the director.

Filming took place in South Wales and on location in Oxford and Venice.
