  HBO ordered a second season of ''Game of Thrones'' on April 19, 2011, two days after the series premiere. The second season obtained a 15% increase in budget in order to be able to stage the war's most important battle, the Battle of the Blackwater, in episode nine.
  Filming took place during 106 shooting days. During three-quarters of those, two crews ("Dragon" and "Wolf") were working simultaneously in different locations.
