Christie, 36, known for portraying the warrior Brienne of Tarth in the HBO fantasy-drama, said all the projects have women roles that eschew the stereotypical narratives that many female characters are forced to follow in film, reported Variety.
Christie plays Captain Phasma, in "Star Wars".
"I don't think many female actors get the opportunity to play a part where they're not having to think about the way their face looks... I found exactly the same thing with Brienne of Tarth, and that was very liberating.
The actress said "Game of Thrones" provides opportunities for both women and men on the show.
"I totally fell in love with the character (of Brienne), but the books were so fascinating because the narratives were so unconventional.
"There were character viewpoints from women, and women were written about in a three-dimensional way with depth, with reality, with huge positivity and with faults - you've got human beings.
