In January 2013, more than a year before the release of this movie, Grace Kelly's children Prince Albert, Princess Caroline, and Princess Stephanie of Monaco, issued a joint statement saying they had no association with the production. The family added that this movie contains major historical inaccuracies, and that Director Olivier Dahan ignored their requests for changes.
Nicole Kidman has stated that the movie is not a documentary, nor a biopic. Instead, it is a study of Grace Kelly's vulnerability and humanity.
In September 2014, before this movie's release in the U.S. was sorted out, Nicole Kidman admitted in a BBC interview with Simon Mayo that the movie had problems: "I did do my best and obviously it didn't work."
The script was listed in the 2011 "Black List" as one of the best-liked unproduced screenplays of the year.
