The 22-year-old actress, who shot to fame as Hermione Granger in the Harry Potter franchise, is in talks to take up the racy role.

An insider say bosses feel Emma Watson would be perfect for the part of Anastasia Steele, thanks to a combination of her acting skills and believable innocence.

Meanwhile, the debate still rages on over who will win the role of handsome billionaire, Christian Grey.

So far Ryan Gosling, Robert Pattinson and Michael Fassbender are all strong contenders for the part, while Vampire Diaries actor Ian Somerhalder, Superman star Henry Cavill and Brit boy Eddie Redmayne are also said to be in the running.

But as yet there's been no word from the Actress herself as to whether she would accept the role.

It’s very common for a star who has grown up in the spotlight to experience backlash when coming of age, and breaking into more adult theme content. However, Waston is one of the classiest actors in Hollywood, and is expected to handle herself well if chosen for the role.
