Anne Hathaway - One Day Author Backs Anne Hathaway Over Accent

The Devil Wears Prada beauty plays British-born Emma in the film, but many critics have been left unimpressed with Hathaway's regional dialect.

However, David Nicholls, who wrote the hit 2009 novel on which the movie is based, is adamant Hathaway has done his literary creation justice.

He says, "I just really hope that people can go into the cinema open-minded. Loads of British actresses go in the other direction and put on an American accent and we don't even notice.

"Anne is wonderful in the film, very sweet and funny, and has brought Emma to life in a way that I couldn't have anticipated."
