Sky Atlantic’s new show Britannia is everything you didn’t know about the dark and dirty world of Roman Britain. Here are 7 reasons to watch.

NEW Sky Atlantic show Britannia is offering you the opportunity to delve into the untold dark and dirty world of Roman Britain.

But, that isn’t the only reason it's worth a watch. From its stellar ensemble cast, award winning writer and exciting themes there’s something for everyone.

Here are 7 reasons you need to watch when all episodes are available on Sky Atlantic on 18 January.

1. It’s got a star-studded cast

It stars David Morrissey as a Roman General, Zoe Wannamaker as a Celtic Queen and Mackenzie Crook as a druid, amongst many others.

2. Learn about the dark and dirty side of Roman Britain

The world as we know it used to be very different when the romans were ruling Britain. Britannia will see you thrown into a world that’s all about sex, booze, power and fighting.

3. It’s set in Britain

So many of our favourite shows are set abroad, or even in made up or mythical lands. Britannia is different because not only is it set in Britain, but it’s set in our past and based on a time in our history. (We should say, though it's all based on history, it's not all strictly true. It's Jez Butterworth's interpretation of a fairly unknown part of history).

4. Find out more about the powerful Druids

Mackenzie Crook (Pirates of The Caribbean) stars in Britannia as Veran the leader of the Druids. Feared and respected all at once, Veran answers to no one but the gods. Tune in to find out why the Druids were so powerful in Roman Britain.

5. Experience a world run by wild warrior women

Britannia is set in 43AD, 100 years after the first failed attempt by the roman army to take Britain. At this time, our island was overrun with wild warrior women heading up their different tribes. Britannia will show the power struggle between these women, the druids and the romans.

6. It’s written by Jez Butterworth

Multi award winning screenwriter and playwright Jez Butterworth is behind the show. With movies like Spectre and Black Mass in his portfolio he’s sure to have created an exciting and action packed story.

7. Get a taste of what life could have been like

The story centres on the power struggle between the Celts, Druids and Romans. Each group has a different set of surprising and shocking traditions, traits and attitudes. Find out more about how Britain could have been if someone else won.

Britannia is exclusive to Sky Atlantic, and all episodes are available on Sky Atlantic from 18 January.
