Answer the following question: Question: Who was the greatest murderess in the history of mankind? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Bathory Context: The gruesome tale of Countess Elizabeth Bathory, notorious yet obscure, has been recounted by historians, writers, poets, playwrights, musicians, painters, and moviemakers. Tradition has it that Countess Bathory was the greatest murderess in the history of humankind, as documented by her entry in the Guinness Book of Records.She tortured her victims, exclusively women, before killing them. She bathed in their blood, and tore the flesh from their bodies with her teeth while they were still alive. But is that really true? In four centuries, no historical document has been found to reveal what had exactly happened. The plot of the film diametrically opposes the established legend. [D-Man2010]Bathory is a European co-production film written and directed by the Slovak filmmaker Juraj Jakubisko. The filming started in December 2005, and the film was released in July 2008. This is Jakubisko's first English-language film.The film is based on the story of Elizabeth Bathory, a 16th/17th century Hungarian countess. Her story takes place in a part of the Kingdom of Hungary, now Slovakia. She is infamous for killing many young women because according to legend she thought that bathing in their blood would preserve her youth. Eventually the royal authorities investigated, and she was walled up in her castle, where she died three years later. [D-Man2010]
