Emilia Clarke has revealed she felt uncomfortable with some of her nude scenes in Game Of Thrones.
The British actress played queen Daenerys Targaryen in HBO's sprawling epic, which became notorious for its explicit portrayal of sex and violence.
Clarke, who was 23 when she started filming Game Of Thrones, said she would be in tears before shooting certain nude scenes.
Speaking on actor Dax Shepard's podcast, she said: "I took the job and then they sent me the scripts and I was reading them, and I was like, 'Oh, there's the catch!'
"But I'd come fresh from drama school and I approached it as a job, if it's in the script then it's clearly needed, this is what this is and I'm going to make sense of it. Everything's going to be cool."
Clarke, 33, added: "I've never been on a film set like this before, I'd been on a film set twice before then, and I'm now on a film set completely naked with all of these people, and I don't know what I'm meant to do, and I don't know what's expected of me, and I don't know what you want, and I don't know what I want.
"Regardless of there being nudity or not, I would have spent that first season thinking I'm not worthy of requiring anything; I'm not worthy of needing anything at all."
However Clarke, who credited her Game Of Thrones co-star Jason Momoa with encouraging her to speak up about her reservations, said she became more "savvy" in her later roles.
She said: "I've had fights on set before where I'm like, 'No, the sheet stays up,' and they're like, 'You don't wanna disappoint your Game of Thrones fans.' And I'm like, 'F*** you.'"
Representatives for HBO and Game Of Thrones creators David Benioff and DB Weiss have been contacted for comment.
