(FILES) -- A file photo taken on April 19, 1956 shows Prince Rainier III of Monaco and US actress and princess of Monaco Grace Kelly saluting the crowd as they leave Saint Nicholas' Cathedral after their wedding ceremony in Monaco. Monaco's royals on May 2, 2014 accused those behind a biopic starring Nicole Kidman as their mother Grace of hijacking their family history, just days before the film premieres at the Cannes Film Festival. In a statement, Prince Albert II and Princesses Caroline and Stephanie said the film did not accurately portray events involving their mother, the Hollywood actress who married Monaco's Prince Rainier III in 1956.
