Naomi Watts has defended her portrayal of the Princess of Wales, saying that although the film may be sooner than some expected, "it was a story that was going to be told."
Speaking the day before the UK premiere, Watts told ITV News correspondent Nina Nannar of the difficulty in capturing what made Princess Diana so instantly recognisable - her voice and mannerisms.
Director Oliver Hirschbiegel said that although 'Diana' will undoubtedly have an effect on the princess' sons, William and Harry, they were used to scrutiny and the attention their mother garnered, throughout her life and since her death.
Watts said that while preparing to play the people's princess she had two vocal coaches and it required "a lot of hard work."
Watts also spoke about her fears of taking on the role and how she actually turned the part down twice because of her concerns.
- 'Diana' will be released in the UK on 20th September
