After the shocks of series three, Game of Thrones star Kit Harington has said that fans should prepare themselves for even more character deaths in season four.

Speaking to Access Hollywood, Harington, who plays Jon Snow, said there would be "more deaths this season than any other".

"I can't tell you who dies," he said. "You'd think they'd tone the deaths down, but they don't."

Harington added: "They've realised that's a successful option, so they're just killing more people than they've ever killed."
