Most of the Northumbrian soldiers in this episode were played by extras who usually play vikings. Many of them felt strange taking part of the torture of their "leader".
Travis Fimmel said this was a very difficult episode because of the weather conditions. It was very cold and sometimes raining on the set.
This was the only episode not to have a new scene with Floki (Gustaf Skarsgård), though he does appear in Ragnar's flashback.
This is the highest rated episode of the series.
