"Fifty Shades of Grey" set the record as the fastest-selling paperback of all time. It is the first novel in a trilogy about the intimate relationship between a college graduate, Anastasia Steele, and a young and wealthy entrepreneur, Christian Grey.

Watson told EW.com last July, "I haven't read the book, I haven't read a script, nothing," she said.

E.L James went to Twitter on Friday, March 15, to say, "There have been no casting decisions made about Fifty Shades."

A day later, Watson tweeted, "Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life."

Watson then sent out a smiley face emoticon noting that it was "sorted then."
