Jessica Chastain, who recently lit up the screen in The Help, is reportedly in talks to star in Caught in Flight, which will focus on Diana’s relationship with heart surgeon Dr. Hasnat Kahn.
Theron was said to be in line for Closely Guarded Secret, based on the book by Diana’s bodyguard Ken Wharfe. And both Knightley and Johansson were rumored to star in a movie simply titled Diana.
The projects have yet to go before the cameras, but which actress would you like to see wearing Diana’s crown?
