The film, directed by Chilean filmmaker Pablo Larrain, is not a historical document. Rather, it’s how Larrain and screenwriter Steven Knight imagine the turmoil Diana was going through as she joined the royal family at Sandringham for what would be her last Christmas.The princess was pronounced dead at 4.57am on August 31, 1997 — as it happens, I was here in Venice then, as well — but it’s clear that people are still obsessed with her.
A poster for the film, showing Stewart wearing a Chanel haute couture embroidered dress . . . and bent double, throwing up (though the loo has been excised from the image), has already gone viral.
