Naomi Watts: Backless Dress at 'The Impossible' Premiere!

Naomi Watts looks stunning at the UK charity premiere of her film The Impossible on Monday (November 19) at the BFI IMAX in London, England.

The 44-year-old actress, who wore a Tom Ford cady kaftan dress and python black pumps, was joined by her co-star Ewan McGregor, who suited up in Vivienne Westwood MAN.

The Impossible is an account of a family caught, with tens of thousands of strangers, in the mayhem of one of the worst natural catastrophes of our time.
