Kit Harington thinks the final season of 'Game of Thrones' was "designed to break" the cast, because they were so exhausted by the time show wrapped.
The hit HBO fantasy show is set to return for its eighth and final season in April, and Kit - who plays Jon Snow - has said that filming for the show's final episodes left all the cast so "sleep deprived" and "broken", that they'd "had enough" of being on set by the time the programme wrapped.
Speaking to GQ Australia, he said: "The last season of 'Thrones', seemed to be designed to break us. I remember everyone walking around towards the end going, 'I've had enough now. I love this, it's been the best thing in my life, I'll miss it one day - but I'm done.'"
Several cast members of the show - which is based on the 'A Song of Ice and Fire' book series by George R.R. Martin - have previously spoken about the highly-anticipated final season, with Gwendoline Christie teasing that viewers are in for a shock so big they'll need to seek "professional help".
The 40-year-old actress - who stars as Brienne of Tarth - said: "You're going to need therapy. I think just the show ending is going to send all of the world into professional help."
Gwendoline also believes the show's finale will be "incredibly emotional", especially for the cast, as she says the programme has been a "truly incredible thing" to be involved with.
She added: "I think it's going to make me incredibly emotional. We're all emotional about the fact that this is the end, and this is the end of something incredibly significant for all of us, and it's been a truly incredible thing to be a part of."
And Emilia Clarke - who plays Daenerys Targaryen - also teased the show's finale when she said "everything" from the costumes to the camera checks have been "more intense" than ever before.
She said: "[Camera] checks take longer, costumes are a bit better, hair and makeup a bit sharper - every choice, every conversation, every attitude, has this air of 'this is it.' Everything feels more intense."
'Game of Thrones' will return in April, though no specific date has yet been announced.
