“It’s one of the saddest stories to exist ever, and I don’t want to just play Diana—I want to know her implicitly,” Stewart said. “I haven’t been this excited about playing a part, by the way, in so long.” Spencer, which starts shooting in January, is being directed by Pablo Larraíne and focuses on Diana (whose maiden name is Spencer) during a 1992 weekend when the princess was deciding what to do about her failing marriage to Prince Charles. “Kristen can be many things, and she can be very mysterious and very fragile and ultimately very strong as well, which is what we need,” Larraíne told Deadline in June. “The combination of those elements made me think of her. The way she responded to the script and how she is approaching the character, it’s very beautiful to see. I think she’s going to do something stunning and intriguing at the same time. She is this force of nature.” As for what Stewart is most concerned about in playing the princess, she told DuVall, “The accent is intimidating … because people know that voice, and it’s so, so distinct and particular. I’m working on it now and already have my dialect coach.” As far as research goes, Stewart said she’s read two and a half Princess Diana biographies thus far. “I’m finishing all the material before I actually go make the movie,” she said confidently.
