"The first season we got the scripts like you should get them and then you could sit and do notes and stuff. And then after a couple of years, they got paranoid because there was some leaks so we had to get them only digital, on a PDF file.
"Game of Thrones" season eight will film until summer next year, with the six final episodes of the series set to debut at some point towards the end of 2018 or in 2019.
