Nicole Kidman’s highly anticipated biopic about Hollywood star Grace Kelly is being slammed by the ruling family of the tiny Mediterranean principality of Monaco. The film focuses on her marriage to the tax haven’s ruler Prince Rainier III.

Prince Albert, the son of Rainier and Kelly, and his two sisters, Princess Caroline and Princess Stephanie, are all protesting the movie.

The royal family issued a statement attacking the film as “pointlessly glamorized and historically inaccurate,” according to French daily le Figaro. Some scenes were branded “pure fiction.”

What the royal statement had to say: “We have had absolutely no association with this project which is claims to be about the lives of our parents. For us, this film does not constitute a biographical work, but portrays only a part of her life and has been pointlessly glamored, and contains important historical inaccuracies as well as scenes of pure fiction.

The film focuses on Kelly’s life after her 1956 marriage to Albert’s father. She gave up a successful film career to become Princess Grace of Monaco. From outside appearances their lives were storybook. But behind the scenes their relationship was said to be rocky.

In 1982, Kelly died at age 52 in a car accident on a treacherous Monaco road. Her Jaguar sedan plunged down an embankment. She was reportedly arguing with Princess Stephanie, who was in the car. It’s never been fully resolved who was driving. Stephanie, who was 17 at the time, only received minor injuries.

For her part Kidman has said she was interested in the film because it focuses on Grace’s transition from film star to Princess in 1962.

“It reveals her great humanity but also her fears and frailties as she leaves her career behind,” she said.

It also stars UK actors Robert Lindsay as Greek shipping billionaire Aristotle Onassis, and Derek Jacobi as Count Fernando D’Aillieres. Tim Roth plays Prince Rainier.

The movie is due for release in 2014.
