Downfall director Oliver Hirschbiegel's Princess Diana biopic is currently filming in Croatia, and today brings us a first look at headliner Naomi Watts in character as the late English rose.

Caught in Flight will follow Princess Di's life during the two years leading up to her tragic death in 1997. Particularly, the film will focus on the royal's relationship with British-Pakistani heart and lung surgeon Dr. Hasnat Kahn, which ended shortly before the fatal accident.

"She is a part of our history, an incredible woman and fascinating but a tragic ending," Watts told the Press Association after landing the lead role back in February. "The filmmakers came to me and it's a good script and it's very scary and I kind of wanted to say 'no' but I couldn't."
