New film on Queen Elizabeth

Britain's Queen Elizabeth and her sister Princess Margaret are set to be the focus of a new film.

'Girls' Night Out' will tell the true story of the royal sisters as they are allowed out of Buckingham Palace in London for one night to celebrate the end of World War II in Europe as chronicled by writer Trevor De Silva.

While no actress has yet been lined up to play the 84-year-old monarch, 16-year-old actress Dakota Fanning will play Princess Margaret.

Margaret married photographer Antony Armstrong-Jones in 1960 and had two children, David, Viscount Linley in 1961 and Lady Sarah in 1964.but the couple divorced in 1978. She was then linked to a number of men before her health deteriorated later in life as she suffered with pneumonia and had at least three strokes. Margaret died in 2002 aged 71.

This is not the first time the sisters have been depicted on screen, they are currently being portrayed in the Academy Award nominated 'The King's Speech' based on their father King George VI.
