The trailer for the biopic of Diana Princess of Wales has been unveiled and Naomi Watts has certainly proved to be a stunning choice.

Naomi, 44, plays the much loved mother of Princes William and Harry in a big screen adaptation of her life, directed by German director Oliver Hirschbiegel.

The film, simply titled Diana, is due for release later this year and will focus on the Princess’s relationships with heart surgeon Dr Hasnat Khan (to be played by Naveen Andrews) and Dodi Fayed (portrayed by Cas Anvar).
