Twilight star Kristen Stewart will play Princess Diana in an upcoming movie about the late princess, according to a new report.

The flick, titled Spencer, is centred on ‘a critical weekend in the early ’90s when Diana decided her marriage to Prince Charles wasn’t working’, according to Deadline.

The movie is set across three days during the Christmas holidays in the House of Windsor in the Sandringham estate in Norfolk and is about the princess ‘finding herself, about understanding that possibly the most important thing for her is to be well, and to be with herself and by herself’, according to director Pablo Larraín.
