Maisie Williams has said she was "broken as a human" after a gruelling shoot for an epic battle in the highly-anticipated Game of Thrones final season.

The actress, who plays Arya Stark in the hit HBO fantasy series, has opened up about filming a battle scene which she said was "physically draining" and made her "just want to cry".

In an interview with Entertainment Weekly, the 21-year-old star revealed that a year before filming started she was told to start training as the scenes would be "really hard".

She said: ''And I said, 'Yeah, yeah, yeah.' But nothing can prepare you for how physically draining it is. It's night after night, and again and again, and it just doesn't stop.

"You can't get sick, and you have to look out for yourself because there's so much to do that nobody else can do ... there are moments you're just broken as a human and just want to cry.''

The episode will chronicle the great battle of Winterfell and will see many of the show's favourite characters team up to fight the Night King and his army.

It took 11 weeks of gruelling night shoots to capture the epic battle.

Ian Glen said filming fight scene was "the most unpleasant experience"

Williams' co-star Iain Glen, who plays Ser Jorah Mormont on the show, agreed that the fight was was "the most unpleasant experience" he's ever filmed whilst on the show.

He said: "A real test, really miserable. You get to sleep at seven in the morning and when you wake in the midday you're still so spent you can't really do anything, and then you're back.

"You have no life outside it. You have an absolute f***ed bunch of actors. But without getting too method [acting] about it, on screen it bleeds through to the reality of the Thrones world."

The Hound actor Rory McCann added: "Everybody prays they never have to do this again."

The final season of Game of Thrones will air in April.
