Jez Butterworth, the Tony-nominated playwright of Jerusalem and The River, is at work on an original drama series for Amazon and the U.K.’s Sky, entitled Britannia, according to Deadline.com.

Kelly Reilly, David Morrissey, Zoë Wanamaker and Stanley Weber are reported to star in the series, set in 43 A.D. and charting the Roman invasion of what would become Great Britain. Britannia is described as a “mysterious land” ruled by wild warrior women and powerful druids who can channel the forces of the underworld.

The 10-part series will also include Hugo Speer, Nikolaj Lie Kaas, Stanley Weber, Eleanor Worthington-Cox and Ian McDiarmid.

Jez and Tom Butterworth will write alongside Richard McBrien, and the series will be shot in Prague and Wales. It is planned to air on Sky 1 in the U.K. and Ireland and be available on Amazon Prime Video Stateside in 2017.

Vertigo Films will produce in association with Neal Street Productions. Vertigo’s James Richardson will executive produce with Pippa Harris and Nicolas Brown from Neal Street and Anne Thomopoulos. Rick McCallum is also a producer.
