Maisie Williams: Success of Game of Thrones is daunting
Game of Thrones star Maisie Williams has said the success of the TV series is "daunting".
The 17-year-old, who plays the character of Arya Stark in the show, also said there weren't that many viewers for seasons one and two.
Speaking to Nick Grimshaw on the Radio 1 Breakfast Show, she said: "The success didn't happen overnight.
"It happened gradually, which was great for the younger members of the cast to get used to."
The American TV drama is an adaptation of George R. R. Martin's series of fantasy novels A Song of Ice and Fire.
The series, now in its fourth season on Sky Atlantic, has recently been commissioned for a fifth and sixth series.
Williams, who was born in Bristol, was 12 when she became a member of the show's cast but says she wasn't bothered by fans early on.
"The viewing figures keep going up and up and people are catching up with the box sets now," she said.
"It's really great, but also really daunting. During season one and two I didn't get recognised."
The first Game of Thrones was filmed in a Belfast studio and on location in Northern Ireland, Malta, Scotland, Croatia, Iceland and Morocco.
It premiered on HBO in the US in 2011.
There is a small break in filming at the moment but series five will start shooting in June or July, and Williams was careful not to give too much away or give out any spoilers.
She revealed that the filming of stunts often happens a couple of months before the cast has seen the script.
"They keep it so locked up, it's so top secret," she said.
She describes her character as a sword fighting "bad ass" but says she is nothing like that in real life.
"I'm not that cool but it's nice to pretend to be that cool," she said. "I have the whole world fooled."
When asked about the threat of her character being killed off, she said: "You've got to be nice to the script writers, but no-one tells me anything."
