WOW! New Trailer For Princess Diana Film Shows Her With Her Last Love

We couldn't be more excited about the release of Oliver Hirschbiegel's Diana biopic - especially now that a new trailer has revealed more about the relationship she had with heart surgeon Dr. Hasnat Khan. That's right, it was the heart surgeon before Dodi al-Fayed AND p.s it looks like the former has a bigger role to play.

Naveen Andrews plays alongside leading lady Naomi Watts in the film which looks at the last two years of Diana's life - it was through her avid charity work that she met Hasnat.

The trailer documents the early stages of the relationship with Hasnat where Diana reveals that: 'He doesn't treat me like a princess, it's almost like he doesn't know who I am". Not only was this relationship kept on the downlow but - as the trailer intimates - it was destined to fail from the start.

Roll on 20 September when the movie hits the big screen, then and only then will we get to see the full story - and see Naomi take on this huge role. Until then, take a look at the trailer below...
