Grace of Monaco takes place six years after Kelly's picture-perfect marriage to Prince Rainier III, and depicts the dark underside of her marriage. Grace wants to go back to Hollywood to act -- Hitchcock wants her -- but Rainier wants her to maintain her royal image.
The film was originally slated for a November 2013 release -- just in time for awards season -- but will open May's Cannes Film Festival instead. It might have had something to do with avoiding the fallout from Naomi Watts' Princess Diana biopic last year, a critical and commercial flop.
