This April, Game of Thrones fans will finally see the eighth and final season of their favourite series, which has just unveiled a little more in a first teaser. And this final season promises to be HUGE.The filming was so long and intense that it wore out the actors. ‘The last season of Game of Thrones seemed to be thought up to break us! Everyone was broken at the end, I don’t know if we were crying because we were sad that it was over or we were crying because it was really exhausting…’ explained Kit Harrington, who plays Jon Snow, to GQ.But that's not all. The English actor also added, ‘We were totally sleep deprived. It was as if this final season had been designed to make us think “Frankly, I'm sick of it!” I remember at the end we were all saying "I'm sick of it now. I loved it, it was the best thing in my life, I'll miss it one day... but for now, I’m done with it!”’ We cannot wait to see that on screen!Check out the video above for more on why the Game Of Thrones final season is likely to break all our hearts!
