Yet, this was the exact reason she turned down the lead role in "Fifty Shades of Grey."
In an interview with The Hollywood Reporter, Clarke said that she doesn't want to build an entire career off of it.
"I'd done nudity before and was concerned with being labeled for doing it again," she explained. "No regrets."
Clarke was not the only big name to turn down "Fifty Shades," which has grossed about $558.6 million worldwide since its February 13 release.
Shailene Woodley was an early favorite to play Anastasia Steele, but she had to turn it down because of press obligations for "Divergent." Ryan Gosling was a possible contender for Christian Grey, because of his strict "no sequels" philosophy.
Because of her busy "Game of Thrones" shooting schedule, Clarke has had to turn down several other films as well, including Oliver Stone's "Snowden."But with a reported salary of $7 million per season for "Thrones" (Clarke denies this number, and simply says that the show "takes very good care of [her]"), and a starring role in the upcoming "Terminator: Genisys," out July 1, the 28-year-old actress is doing all right for herself.
