Emilia Clarke of “Game Of Thrones” fame had turned to Wikipedia before auditioning for the HBO hit show. Clarke, who was named Esquire’s “Sexiest Woman Alive 2015” on Tuesday, told the magazine she did not fit the appearance of the character of Daenerys Targaryen, also known as the “Mother of Dragons,” when her agent told her to audition for the role.

“My agent told the casting director, 'I know that the breakdown for this character is tall and willowy and blonde. I know she's short and round and brown, but I'd like you to see her,’” Clarke told Esquire. “I had two scenes which told me nothing and not very much time in which to read all those [George R. R. Martin] books. So I did what every good actor does and Wikipedia'd the living crap out of it."

Clarke admitted that playing the role was initially difficult for her because of the nudity in the TV show. "Once, I had to take a little time out," Clarke said, confessing that at 23, it was tough for her to expose her body. "I said I needed a cup of tea, had a bit of a cry, and was ready for the next scene."

Besides “Game Of Thrones,” the 28-year-old actress was also seen alongside Arnold Schwarzenegger in “Terminator Genisys,” which was released in June.

Clarke will feature on the cover of Esquire magazine's November issue that will hit the stands on Tuesday.
