Monaco royals Prince Albert and his two sisters condemned the upcoming film 'Grace of Monaco' starring Nicole Kidman as Grace Kelly as a 'farce'. Ms Kelly, a former Hollywood actress, married Prince Rainier of Monaco in 1956 and became Princess Grace.

The royals labelled the film as a 'farce' upon watching the trailer which was released few days ago. Prince Albert and his sisters - Princess Caroline and Princess Stephanie said the film was based on wrong historical references and had no relation with the reality.

"The trailer appears to be a farce and confirms the totally fictional nature of this film..The Princely Family does not in any way wish to be associated with this film which reflects no reality and regrets that its history has been misappropriated for purely commercial purposes,"  the Prince and the princesses said in a joint statement.

Grace Kelly starred in yesteryear Hollywood hits such as  'To Catch a Thief' and 'High Society' as well as Alfred Hitchcock's 'Rear Window' and 'Dial M for Murder' and died in a tragic car crash in 1982. Grace of Monaco is scheduled to be released in Cannes Film Festival on May 14.

It was widely touted as a biopic of Grace Kelly and the Kingdom of Monaco. Director Olivier Dahan and the producers have refused to respond to the statement of the royals. But sources report that the producers are planning to decline the US distribution rights of the film as they are dissatisfied with the final version.
