The newest addition to "Game of Thrones" season 5 promised even more surprises when the HBO hit series returns in April. Meanwhile, the cast apparently hates spoilers being spread in various websites.

Jonathan Pryce will play the role of the religious leader, High Sparrow, in "Game of Thrones" season 5, described by Variety as "who might be the only actual King's Landing do-gooder."

Interviewed by Liverpool Echo, the veteran actor said, "I can't give too much away but there are some real surprises this season. Some surprise deaths too, but then that's Game of Thrones."

While fans are anticipating spoilers for season 5 of "Game of Thrones," the cast members apparently are not fans of trolls.

During the promotional video published on IGN, the cast members are asked what they think of the "Game of Thrones" season 5 spoilers.

Nathalie Emmanuel, who plays Missandei, said, "I think It's mean, I mean don't spoil it for everyone."

"I hate that. You know, if you're about to watch a film and then somebody tells you the ending. It's so frustrating," she added.

John Bradley, who plays Sam, weighed in, "'Game of Thrones' is a show that relies so much on guttural response and very, very quick changes of mood and very, very quick changes of narrative and action."

"To deprive people the chance of experiencing that in the way we want them to experience it, it's kind of cruel," he added. "It's detrimental to the show."

Alfie Allen, who plays Theon Greyjoy/Reek, added, "They can frankly just, you know, get a life. Why are you ruining everyone else's fun?

He then looked into the camera and pointed, "Stop that, Internet trolls."

Nevertheless, watch out for more "Game of Thrones" season 5 spoilers which will be published here as they come along ahead of the April 2015 airing date.
