(Although Game of Thrones team would probably tell you the horses were a pain in the rear.)
Just last season, the HBO drama aired an episode called “The Battle of the Bastards” in which soldiers supporting Jon Snow fought against soldiers supporting Ramsay Bolton–many of them on horseback.
Rachel Weisz wasn’t specific when she talked about what her horse on the set of My Cousin Rachel was previously doing on Game of Thrones, but that movie has featured plenty of fighting scenes in the past.
There were a lot of horses charging and more, and it’s nice to know that they were properly trained to get the shots needed without causing any problems for the horses themselves.
