David Morrissey, Kelly Reilly, Zoe Wanamaker, Ian McDiarmid and Mackenzie Crook star in the series that takes place in 43 AD (very olden tymes), and centers on the Romans quest for power over the Celtics. There will also be Druids and maybe some supernatural jazz? I don’t know, but it also have Reilly wielding a bow and arrow which is worth the price of admission alone. Here’s the official synopsis:

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.

“Britannia” launches on Sky Atlantic tomorrow in the UK, and will hit Amazon Prime stateside later this year.
