The actress, who played the powerful and heroic Brienne of Tarth in the cult hit show was speaking inÂ GQ StyleÂ for the magazineâ€™s autumn/winter 2019 issue.
In the interview Christie emphasised the importance of embracing who you are particularly if you do not â€œfit into societyâ€ by conventional standards.
â€œI think, because my body seems to draw such extreme responses from people, that, well… itâ€™s fight or flight, isnâ€™t it? Sink or swim,â€ she said of her 6 ft 3â€ frame, according toÂ The Independent.
â€œYou either exist in a state of shame about not fitting into society or you embrace what you have.â€
The star also discuss how touched she has been to feel able to play a role in helping some women feel more â€œrepresentedâ€ on film and television.
â€œSo many women come up to me and talk about what it means to feel represented outside of the constraints of conventional society,â€ Christie said.
â€œIn 2011, I didnâ€™t think I would ever see women that looked like me in mainstream entertainment. It felt like there was one mould that wouldnâ€™t be broken andÂ diversityÂ was not part of the conversation.
â€œSo the fact that Brienne existed? Wow.â€
The starâ€™s determined attitude has won fans worldwide and was illustrated earlier this year when she submitted herself as a potential nominee for a Best Supporting Actress Emmy for her role on the HBO series.
â€œItâ€™s something I find hard to do, like everyone else, but I would like to be in charge of my own destiny,â€ Christie told theÂ Los Angeles Times.
â€œAnd I would like to endeavour to give myself opportunities. Particularly when working very hard on something very special and youâ€™ve pushed yourself beyond your limits.â€
