Naomi Watts will bring Princess Diana back to life on the big screen in Diana, and if you're curious how she does, you can get a sneak peek in this exclusive clip. The film, which premieres stateside on Nov. 1, is based on Kate Snell's 2001 book Diana: Her Last Love. Thanks to the movie, nostalgic royal watchers can get a look at Diana's clandestine relationship with Dr. Hasnat Khan, a Pakistani heart surgeon Diana dated between 1995 and 1997. And as we can see in this clip, Diana reportedly tried her best to keep the affair a secret. Ahead of Diana's American debut, the filmmakers have also created a Diana the Movie Tumblr, which provides some good side-by-side pictures of the people's princess and Naomi. Watch the clip and weigh in: do you think she's captured Diana?
