Jessica Chastain will portray Princess Diana in the biopic Caught in Flight from director Oliver Hirschbiegel.

The movie will revolve around Princess Diana's real-life secret affair with heart surgeon, Dr. Hasnat Kahn, "who was said to be the love of her life." Their two-year affair began in 1995, and Kahn maintained his silence until he spoke on record to The Telegraph in 2008. The movie is described as a "love story between a princess locked in a tower and an ordinary man."

Production will begin in March 2012.
