Express.co.uk has had an exclusive look at the first series ahead of broadcast and can confirm that the show sees some breathtaking coastal scenery. But is it real or CGI?
Well it turns out that some is computer generated and sets are built specially for the show, but other backdrop locations include the Czech Republic and Wales.
Ten large sets were built for the drama, and more than 20 locations in total feature in the series.
Some interior shots were filmed at Barrandov Studios in Prague.Related articles

Sky Atlantic also had a copy of Stonehenge made, along with dwellings and a meadow near the small town of Mořinka.
Velká Amerika, an abandoned limestone quarry near Mořina village, served as a spectacular backdrop, while a large set with footbridges, stalls, carts and boats were specially built for the production beside the lake.
The old quarry of Alkazar was also used, along with its system of underground tunnels.
Crew also carried out filming in the Prachov Rocks area near Hrubá Skála, along with building a primitive settlement in the cove beneath Nash Point in South Wales, and scenic horse riding shots of Worms Head at Rhossili Bay on a sandy beach in Gower Peninsula.
