Naomi Watts Pictures as Princess Diana on the Set of Caught in Flight

Naomi Watts stepped onto the London set of her forthcoming feature, Caught in Flight, yesterday. Naomi's playing the role of Princess Diana and when decked out in full hair and makeup bears a striking resemblance to the late royal. The film portrays the last two years of Diana's life prior to her untimely death.

Naomi's been spotted in the UK in recent weeks following her brief stay in Cannes during the French film festival. Her time in Europe hasn't been all business: in fact, she was one of the many famous faces on hand last week at Elton John's White Tie & Tiara Ball. Naomi wore a beautiful white and gold Marchesa gown to the bash and partied late into the night at the Chopard-sponsored soiree.
