'Diana' international trailer: Naomi Watts and Naveen Andrews fall in love

A much deeper look at the upcoming Princess Diana biopic "Diana" has been released. The above international trailer shows the struggles of Diana's last great love with heart surgeon Dr. Hasnat Kahn, and promises to be some major awards season bait.

Naomi Watts stars as Diana, Princess of Wales, while "Lost" alum Naveen Andrews plays Kahn. It's no secret that Diana and Kahn fell for one another during the last stage of her life, but that the constant paparazzi intrusion led to conflicts in their relationship. What will be interesting to see is if "Diana" probes as much into Diana's life as it wants us to think it will.

Directed by Oliver Hirschbiegel, "Diana" does not yet have a US release date, but has its first premiere in Hungary on Sept. 19.
