If you've watched this week's Game of Thrones episode, we're sure you'll have been blown away by the spectacular battle scenes. The show has had some impressive combat setpieces over the years (The Blackwater, Castle Black) but they truly outdid themselves this time round.

The show's masterminds were kind enough to put together a 10 minute featurette outlining how they managed to pull off The Battle of Winterfell, and it's a must see for any fan of the show or anyone with an interest TV and film.

We can't even begin to imagine what they have up their sleeves for next week.
