Game of Thrones star on upcoming scene: 'It's hard to watch'

Alfie Allen says some major scenes are set to take place in Game of Thrones' fifth season.

A Game of Thrones star has warned fans of HBO's hit show to "get ready" for an upcoming scene set to make "huge waves".

The series, which screens on Soho in New Zealand, is up to its third episode of its fifth season, with seven remaining.

So far this season, there has been lots of manoeuvrings of the show's main characters, but not a lot of action.

That's set to change, says Alfie Allen, who plays Theon Greyjoy.

"There's something that happens about halfway through this season that is really going to make huge waves. And people aren't going to be happy about it. It's hard to watch," Alfie told website Zap2it.

"I bear witness to this thing, and it's crazy, sort of having to portray how messed up everyone's situation is through my own reactions to what happens," he added.

"Get ready for it."

Allen also hinted that Greyjoy's character is about to undergo a makeover.

"I would go so far as to say maybe Ramsay Bolton is the new Joffrey in town, and then probably me followed closely after that."
