Naomi Watts as Princess Diana: A First Look

The first images of Naomi Watts in character as Princess Diana have hit the internet on Monday making waves.

The English actress, who launched her career in Australia, will play the royal icon and late mother to Prince William and Prince Harry in the upcoming film "Caught In Flight."

Watts was spotted on set in Croatia in an iconic sparkly dress, jewels, and cropped blonde hair that was Diana's signature look. Another image reveals Watts in a dark business suit on the set of "Caught In Flight."

The Academy Award-nominated actress is well known for her roles in "The Ring" and "King Kong," and her portrayal of Diana during shooting is uncanny.

"Caught In Flight" explores the final two years of Princess Diana's life, including her humanitarian work in central Europe and her reported affair with heart surgeon Dr. Hasnat Khan.

Speaking about the Oliver Hirshbiegel-directed film, Watts admitted that accepting the role as Diana was daunting.

"She is a part of our history, an incredible woman and fascinating but a tragic ending," said the 43-year-old actress, according to the Press Association. "The filmmakers came to me and it's a good script and it's very scary and I kind of wanted to say 'no' but I couldn't."

Diana, Princess of Wales was killed at age 36 in a car accident in Paris 15 years ago, but the details of her life continue to capture the media's attention.

"I'm looking forward to it, but am absolutely terrified," added Watts, according to Daily Mail. "It's going to be a tough one, It's a big beat to take on. I just try to do my best."

The biopic on the late princess is expected to hit theaters next year.
