Sky has released a rather gruesome red band trailer for the new historical drama, Britannia and it looks set to give Game of Thrones a run for its money.

The new nine-episode drama, which will air on Sky Atlantic and TV streaming service Now TV, will focus on a time when mystical Druids run free, invincible Celts reign unopposed and invading Romans try to civilise them, but since when did anyone want to be civilised.

The synopsis reads;

Set in 43AD, the captivating, anarchic drama follows the Roman army as they return to crush the Celtic heart of Britannia, a mysterious land led by warrior women and powerful Druids who claim to channel the powerful forces of the underworld.


The show also has a cream of British talent heading up the cast with the likes of The Walking Dead star David Morrissey as Roman general Aulus Platius. Game of Thrones and The Office actor Mackenzie Crook is druid Veran, who’s something of an enigma and claims he was the second man on the planet and is 10,000 years old. Zoe Wanamaker who plays Queen Antedia, the leader of a rival tribe the Regni and saw her only one married off to Cantii princess Kerra. Ian McDiarmid portrays King Pellanor, the leader of the Cantii and the father of the headstrong Kerra. As well as  Kelly Reilly as druid Kerra, who’s a skilled warrior and a member of the Cantii tribe.

Britannia starts on Sky Atlantic on January 18 and all episodes will be available to watch on NOW TV.
