Its the controversial biopic that claims its got the untold story of Dianas final two years.
And, at long last, the first trailer is out.
Weve seen pictures, but this is the long-awaited glimpse at Naomi Watts in action as the Peoples Princess.
With that bouffant 80s blonde look and signature pearls, Naomi Watts looks almost eerily like the People's Princess and as the film clip proves she's got her mannerisms down-pat too.
The film focuses on Dianas relationship with Doctor Hasnat Khan, who supported her humanitarian work before her death.
Directed by Oliver Hirschbiegel, the film co-stars Naveen Andrews as Dr Khan.
Watch the trailer below.
DIANA will be released nationwide on September 20th 2013.
