We're used to stars having dramatic makeovers (or make-unders) for film roles, but we had to do a double take upon seeing these pictures of Nicole Kidman
The natural redhead - and often strawberry blonde - actress is busy filming The Railway Man
in Scotland at the moment, and has swapped her long locks for a fringed brunette bob.
While at first we assumed she could well be wearing a wig, on closer inspection it appears that Nicole really has gone for the chop - it looks real enough to us.
Now that's dedication to your art.
The Aussie actress stars in The Railway Man
alongside Colin Firth
, set for release in 2013.
