The latest Game of Thrones episode, Battle of the Bastards, received critical praise and is a leading contender to win several Emmy awards. James Hibberd and Jethro Nededog looked at the numbers behind the episode:

• 500 extras were hired for the various armies involved. They trained separately from one another to create on-screen rivalry.
• 70 stunt horses were used – the use of real-life horses in battle is incredibly rare for a TV show.
• A typical episode takes about two weeks to shoot. Battle of the Bastards required 25 days.
• There were four camera crews responsible for capturing the action on all the various points on the battlefield.
• The entire season is thought to have cost over $100 million, and this episode is estimated to have been responsible for up to $25 million of that.
