Game of Thrones season 7 showrunner teases 'massive sea battle' bigger than Blackwater

Could the White Walkers be hitting the high seas?

If there's one thing Game of Thrones knows what to do, it's to deliver a spectacle - and, with Daenerys (Emilia Clarke) on her way back to Westeros, season seven looks to be one giant battle sequence (we can hope).

With under a week to go until its return, showrunners of the HBO series have been teasing one of season seven's big battles

David Benioff, one-half of the showrunning duo, confirmed the forthcoming episodes will feature a “magnificent” sequence he believes eclipses one of the series' most memorable.

“There's a massive sea battle that will sail past season two's Blackwater in scope,” he told TV Insider.

“Everyone is facing something more dangerous to all of them than any danger they are to each other.”

It's unclear what “something more dangerous” is referring to, but it could perhaps be something to do with the series' new big bad Euron Greyjoy (Pilou Asbæk), the uncle of characters Yara (Gemma Whelan) and Theon (Alife Allen) who Asbæk himself stated is worse than former villains Joffrey and Ramsay.

Benioff may even be alluding to the White Walkers meaning season seven could well see the Night King hit the high seas for the most groundbreaking action sequence yet.

Game of Thrones returns to HBO on 16 July and will be simulcast at 2am on Sky Atlantic. It will air the following evening (17 July) on Sky Atlantic and NOW TV.
