Emma Watson has certainly grown up a lot since the first days of Harry Potter, but let's not forget that she is still one of Hollywood's sweetest young talents, and that doesn't look like it'll change anytime soon.

Since it was announced that the hit book series 50 Shades of Grey would be adapted to film, casting rumors have been flying about who will star in the raunchy roles of Anastasia Steele and Christian Grey. Somehow, the spotlight always lands right back on Emma for the role of Ana, but there are no shades of grey area about this -- she was black-and-white clear when setting the record straight about this one!

"Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life," she tweeted on Saturday. Although we've been waiting for news about this for months, E! News reports that casting for the film hasn't even begun! (Though surely they've started thinking about it. Since clearly everybody else has.)

Another actress that's consistently denied starring in the film is Elizabeth Olsen, so with these two ladies off the docket, the question of who will take the spotlight in the role of Anastasia still remains. As for the smoldering and sexy Christian, Ian Somerhalder has been attached to the project on several occasions, and seems to be all for it. So... maybe they should just cast him and Nina Dobrev and get this over with already, huh?

Who do you think should star in this film?
