Olivier Dahan’s Grace Of Monaco starring Nicole Kidman will kick off the Cannes Film Festival on May 14, out of competition. There was some confusion yesterday when The Weinstein Co moved Grace off of its previously scheduled March 14 U.S. release date. I suspected this might have something to do with Cannes rather than with reported strife between Harvey Weinstein and director Dahan. Gaumont, which is distributing Grace in France, had, in December, changed its local release date from January 29 to March 19. That move was because the film had only just been finished. When I recently ran into Grace producer Pierre-Ange Le Pogam in Paris, I asked him if the date might change again for a surprise Cannes berth and he gave me a cryptic “Who knows?” I’m promised the biopic about actress turned princess Grace Kelly is a stunner. The film portrays a period in her life after marrying Prince Rainier III (Tim Roth) in 1956. Six years later, amid occasional difficulties in fulfilling her role, she was invited back to Hollywood by Alfred Hitchcock, to star in Marnie. At the time, France was threatening to tax, and even annex, Monaco. The film asks the question: Was Grace still an actress or was she really Princess of Monaco? Frank Langella, Parker Posey, Jeanne Balibar, Derek Jacobi and Paz Vega also star. The festival runs May 14-25.
