Nicole Kidman Stuns at Grace of Monaco Premiere at Cannes, but Grace Kelly Biopic Gets Less-Than-Glowing Reviews

Nicole Kidman, who plays Hollywood superstar turned royal Grace Kelly in the biopic

Ultimately, Grace of Monaco did open the 2014 Cannes Film Festival as scheduled.

But to what end?

Nicole Kidman, who plays Hollywood superstar turned royal Grace Kelly in the biopic, stunned as usual at Wednesday's premiere. The leading lady wore a strapless blue Georgio Armani Privé gown with a lace bustier and three-dimensional embroidery with crystals, baguettes and pearls.

The film itself, however, didn't come off quite as well.

"Cannes opens with a royal biopic worse than Diana," fumed The Guardian's review headline, under which a subhead called it a "breathtaking catastrophe."

Calling the "cringe-factor...ionospherically high," critic Peter Bradshaw wrote, "A fleet of ambulances may have to be stationed outside the Palais to take tuxed audiences to hospital afterwards to have their toes uncurled under general anaesthetic."

Variety's Scott Foundas called the film a "cardboard and frequently cornball melodrama" in which Kidman "never appears to fully connect with the character." The script, he wrote, "is agonizingly airless and contrived."

"The Real Scandal Around Grace of Monaco: It's Not Very Good," notes Time magazine.

Variety reported last month that Weinstein Co. chief exec Harvey Weinstein was considering dropping U.S. distribution of the film all together because he was still unsatisfied with the final cut, after already delaying the release date.

Monaco's royal family had publicly criticized the film's depiction of Prince Rainier III and Princess Grace and had promised that none of the late couple's three children would show up to support the film at Cannes.

Kidman defended the film at a press conference today, saying, "I feel sad because I think that the film has no malice toward the family or particularly towards Grace or Rainier. I understand the protection of the privacy of their mother and father. I want them to know that the performance was done with love and if they see it I think they'd see there's an enormous amount of affection for their parents and for the love story of their parents."
