'50 Shades Of Grey Film': Emma Watson Denies Anna Steele Casting Via Twitter

Emma Watson has denied she's signed up to play Anastasia Steele in the '50 Shades Of Grey' film adaptation.

The 'Harry Potter' star tweeted: "Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life."

Watson spoke out about the saucy role after a Twitter account claiming ties to hacker-activist group Anonymous posted information reportedly taken from internal memos of German studio Constantin Film linking her to the part.

Rumours that Watson will be involved with the film version of the best-selling trilogy have been circulating for months. However, the actress has previously denied that there's any truth to such speculation.

The film adaptation of the raunchy novel is still a way off, so the rumour mill will likely keep churning. A director for the project has yet to be confirmed, and the release date isn't until summer of 2014.
