Naomi Watts is moving to London's Kensington in order to prepare for her role as Princess Diana in an upcoming movie.
'Caught In Flight' starts shooting next month and she wants to soak up surroundings familiar to the late mother of Prince William and Prince Harry.
Researchers will join her at locations Diana frequented, such as The Harbour Club and Beauchamp Place.
A source told The Sun: "Naomi wants to get into character before shooting starts."
The movie is based on the last two years of Diana's life.
Naomi has said she is "absolutely terrified" about taking on the role.
The actress recently said she would only have another baby if she knew she could have a girl.
The 'Fair Game' star has two sons, Alexander, four and three year old Sammy with her partner Liev Schreiber and although the pair have ruled out having any more kids, the 43-year-old, admits she would love a daughter.
She told Style magazine: "I always knew I'd be the mother of two boys. I'm 43 now and I don't know if having any more would work. There are still fights and struggles all the time but I feel that I am coming in to the light."If I knew that I could get pregnant and I knew that I was going to have a girl, I would definitely go for it."
