Kristen Stewart is to portray Britain's Diana, Princes of Wales in a film about the end of her marriage to Prince Charles.
The Hollywood Reporter says the drama from Jackie director Pablo Larraín is called Spencer - the late Diana's maiden name - and is written by Peaky Blinders creator Steven Knight.
The entertainment trade publication says the film is set over Christmas at the British Royal Family's Sandringham Estate as Diana decides that her marriage to Prince Charles is over. Their divorce was finalised in August 1996. Diana was killed in a car crash in Paris in August 1997.
Production on the film is expected to begin early next year.
Twilight star Stewart won rave reviews for her portrayal of the late actress Jean Seberg in recent biopic Seberg.
