Jessica Chastain to Star in Princess Diana Biopic

The project looks at Diana's secret affair with a heart surgeon

Jessica Chastain may not win Oscar gold this year, but it appears she will wear a crown nonetheless.

Chastain, omnipresent in 2011 with roles in movies from “The Tree of Life” to “The Help” to “Take Shelter,” is in talks to play Princess Diana in “Caught in Flight,” according to Indiewire.

The film revolves around a covert affair between the Princess of Wales and a heart surgeon, Dr. Hasnat Kahn. Though Diana was with lover Dodi Al-Fayed during her infamous fatal car crash, Kahn was believed to be the love of her life.

Kahn remained silent about the affair until 2008, when he spoke about it with the Telgeraph. Kahn said Diana was even willing to convert to Islam to make it work.

The film, which will be directed by Oliver Hirschbiegel (“Downfall”), is ready to shoot in several locations, such as Pakistan and Angola, next year. Steven Jeffreys wrote the script.
