Hannah Murray has been spotted looking virtually unrecognisable from the character which kicked off her carer on critcially acclaimed teen show SKINS.
The actress, 33, played mentally un-stable teen Cassie in the show Skins and has since taken on a string of roles which have been widely appreciated by both fans and critics.
But a recent snap of her at a comic con event showed Hannah has gone back to her roots and ditched her character Cassie's blonde locks.
Hannah looked in good spirits as she smiled back at the camera while wearing a Buffy the Vampire Slayer t-shirt and hair flow loose in a side parting.
The actress was in Skins between 2007-2008 and returned again in 2013 for two episodes.
After Skins Hannah went on to read English at Cambridge University.
Following her success on the show, between 2007-2008, she took to the West End to play Mia in the critically acclaimed play That Face, before appearing in popular black-comedy movie In Bruges as well as the ITV adaptation of Agatha Christie's Why Didn't They Ask Evans?
Since then she has starred alongside Johnny Depp in the 2012 film Dark Shadows, Bridgend in 2015 and Detroit with John Boyega in 2017.
But her Game of Thrones casting as Gilly saw her nominated for a Screen Actors Guild (SAG) for her portrayal as a wildling girl, who is both the daughter and wife of Craster.
Although her career had proved impressive, she admits it was her role in American biographical movie Charlie Says starring as Le Leslie Van Houten alongside Matt Smith as infamous killer Charles Manson which saw her digging deep for empathy.
She told Buildseries: "It was testing the limits of my empathy and seeing how much I can stretch that."
She told how after reading the script which tells the story of of a an American girl who is transformed into a cold-blooded killer, it was a 'no brainer' to explore and spent time sitting with the character to ask 'why' which was out of her comfort zone but she felt compelled to do.
She added: "I was interested in how someone can go to that place, and I think it's important to not judge people so harshly where you have people saying 'that could never happen to me', as in the wrong circumstances, this could have happened to a lot of young women."
