The 33-year-old played Daenerys Targaryen in the hit HBO series for eight seasons, starring alongside the likes of Kit Harington, Alfie Allen and Peter Dinklage.

During the recent Edinburgh TV Festival, Emilia revealed how her male co-stars had a number of on-set comforts which weren’t an option for her or her female co-stars.

She said: “The guys in the Night’s Watch, Jon Snow, are wearing a woolly mammoth all the time.

“When we were shooting things in a hot country when they had all of those things on, they had this pump that had its own little generator attached into the costumes.

“They used it to pump cold water into these pipes and cool them all down so underneath they had this weird kind of cooling system.

She continued: “Girls weren’t allowed that. All I could get was the back of my wig to be lifted up.

“It’s too hard, I’ve got a wig on, they don’t make cold packs you know, you put ice packs on yourself.”

Meanwhile Emilia’s co-star Maisie Williams recently opened up about the pressures of starring in the hit show from a young age.

Maisie, 23, was just 12 years old when she started as Arya Stark and in a new interview with The Independent she recalled the downsides of being so young on a hit show.

She said: “Even when I was 12, people were like, ‘Ooh, are you gonna get a drug habit and ruin your life?’ That is the problem, I guess.

“The fact that you’re doing interviews when you’re 12 and no one’s ever addressing why that’s a really difficult and dangerous thing for you to do.

“Everybody wants you to have an opinion on something when you don’t know who you are yet.”
