The newest Hollywood it-girl Jessica Chastain, who was basically in every single Oscar-baiting role this year ranging from a sad, wise housewife in The Tree of Life to a sad, dumb housewife in The Help, is rumored to be up for the role of a possibly sad Princess Diana in a new film about her secret affair with Pakistani heart surgeon Hasnat Kahn. indiewire reports that Caught in Flight it set to go into production next spring with German director Oliver Hirschbiegel at the helm.

The film will depict the affair between the princess and the doctor, which began shortly before her divorce from Prince Charles and lasted for nearly two years. Diana tried desperately to keep the affair on the DL, but she was questioned regularly by the press about her relationship with Kahn. After her death in 1997, close friends reported that Kahn was "the love of her life."

The princess met Dr. Hasnat at the Royal Brompton Hospital in 1995 when she was visiting a friend who was recovering from heart surgery. The couple pursued a quiet two-year affair. Dr. Kahn, who she named “Mr. Wonderful,” maintained an eleven-year silence over the relationship, until he spoke The Telegraph about the affair in 2008. In the article, the relationship is described as being so serious that Diana was thinking of converting to Islam. She wore traditional dress to meet his family on a visit to Pakistan. “The Khans are deeply religious,” the newspaper reported, and “his wall-hangings include a painting that has an inscription of verses from the Koran.” Dr Khan left Britain in 2007. Diana is said to have been heartbroken that he wanted to end the relationship.

This would be the first major film about the princess (if you don't count The Queen, which focused on Queen Elizabeth in the days following Diana's death), although Kiera Knightley was once in talks to play her in a biopic. This may also be the first major starring role for Chastain, who came out of nowhere to star opposite Brad Pitt in The Tree of Life (with her name above the title, no less). Like Diana's life and death, Caught in Flight will likely cause some buzz among those expecting a faithful and favorable portrayal of the princess: the script penned by Steven Jeffreys is rumored to show her "as a damaged person who stalks the doctor after he ends the affair."
