Actor Jonathan Pryce has spilled a delicious little detail about Game Of Thrones season five – he only took on the character of High Sparrow because it's a game changing role.

The veteran actor enters the series in the fifth season, which starts on Foxtel's Showcase channel on April 13, as a High Septon who is considered an avatar of the gods.

Speaking from London, Pryce says that he's never been keen on "swords and sorcery" and he only signed-on because the character was extremely influential although he would not say how.

"If the role hadn't been what it turned out to be for High Sparrow, I probably would not have been involved," Pryce said.
