Emma Watson to star in 'The Perks of Being a Wallflower'

Emma Watson has signed on to star in a Hollywood adaptation of a book criticised for its treatment of sex, drugs and suicide.

The 20-year-old ‘Harry Potter’ actress will play the subject of an adolescent boy’s affections in Stephen Chbosky’s controversial book ‘The Perks of Being a Wallflower’.

Chbosky’s book is among those that have prompted most complaints to the American Library Association, for its treatment of drugs, homosexuality, nudity and offensive language.

“Emma is not afraid to take risks as she grows up as an actress,” the Telegraph quoted one of her associates as saying.
