The British actress, 78, is not returning as the head of the British intelligence service in the upcoming 007 movies after her character dies in 'Skyfall' and is replaced by Ralph Fiennes.
Dench played the character from 1995 to 2012 but her real name remained a mystery until now when Phil Noble spotted the name Olivia Mansfield on her desk in a freeze-frame from Skyfall, the Daily Star reported.
Phil believes the name is a nod to the first head of MI6, Mansfield Smith-Cumming, who adopted M as the code in 1911.
