Game of Thrones star hits out at "snobby" book fans [SPOILERS]

Game of Thrones star Maisie Williams has hit out at "snobby" fans of George RR Martin's original novels.

Williams told TVLine that she dislikes "mean" book readers who spoil the series for fans who have only seen the HBO TV series.

"I'm so sick of going on the internet and seeing all the book readers being snobby, spoiling it for other people - then saying, 'Well, it's not a spoiler. The books have been out for years'," the actress said. "Like, couldn't you just stop being mad for a second and let other people enjoy the show? They feel they have a claim on the series because they read the books first, and I understand that, but they don't need to be mean about it."

Aficionados of Martin's 'A Song of Ice and Fire' franchise were recently left frustrated when Lady Stoneheart - a zombified version of Catelyn Stark - failed to materialise on the TV series.

"That was a massive deal, but honestly, I really like [the backlash]," Williams said. "Book readers think they know what's coming, then we change it and it's really funny to watch their reactions. They're always like, 'That's not what happened in the books, so the show's really bad now' - but really, they just feel insecure because they're used to knowing what's coming next."

Game of Thrones will return to HBO and to Sky Atlantic in the UK in 2015.
