The secrecy surrounding。Game of Thrones。is formidable, even to viewers who just want to avoid spoilers. Gemma Whelan, who plays Yara Greyjoy, didn't know that her initial casting was meant to stay close to the chest, so she went ahead and updated her resume, much to the chagrin of HBO.。

“The first lesson I learnt was when I first got the job. No one told me to keep quiet about it,” she told the U.K. Times。. “I just thought it was normal to pop it in my Spotlight entry, so I wrote on my CV, ‘This summer, Gemma will be playing Yara Greyjoy in Game of Thrones。.’" 。

called me into his office and said, ‘This is very serious. We almost can’t employ you because of this.'” Almost is right, and Whelan ended up playing Yara for the next six seasons (at least). In the meantime, the producers tightened their nondisclosure agreements, and Season 7 -- premiering July 16 -- is more secretive than ever. 。
