Emilia Clarke says she felt pressured to do nude scenes in Game Of Thrones .
The star has revealed she felt uncomfortable with taking her clothes off on the hit show.
The British actress played queen Daenerys Targaryen in HBO's epic, which became notorious for its explicit portrayal of sex and violence.
Emilia, who was 23 when she started filming the hit show, said she would be in tears before shooting certain nude scenes.
Speaking on actor Dax Shepard's podcast, she said: "I've had fights on set before where I'm like, 'No, the sheet stays up'.
"They're like, 'You don't want to disappoint your Game of Thrones fans.' And I'm like, 'F*** you."'
Emilia added: "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.
"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.
"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 Emilia, 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.
