It’s Princess Diana reincarnate (especially the hair) — as Naomi Watts is seen for the first time on the shoot of the film “Caught in Flight.”

The Australian-raised actress has openly admitted she worried about looking “nothing whatsoever like Princess Diana” — but the makeup artists and hairstylists have worked their movie magic.

“Caught in Flight,” set for release next year, will explore Diana’s romance with heart surgeon Hasnat Khan.
