Filming is underway on Spencer, the forthcoming film about Princess Diana starring Kristen Stewart.

To mark the start of production, the film’s producers have released a first-look image of Stewart.

The film focuses on one weekend in the life of Princess Diana, as she spends the Christmas holiday with the Royal Family at the Sandringham estate in Norfolk, and decides to leave her marriage to Prince Charles.

Filming is underway in Germany and the UK, with the film expected to be released later this year. The cast also includes Timothy Spall, Sally Hawkins and Sean Harris.
