Sir Miles Messervy (or M) is a fictional character in Ian Fleming's James Bond series; the character is the Head of Secret Intelligence Service—also known as MI6. M was played by Bernard Lee from the first Bond film Dr. No, until Moonraker. As in the novels, it is hinted that M's real name is Vice Admiral Sir Miles Messervy. While his name was hinted at throughout the novel series and finally revealed in The Man with the Golden Gun, in the film series only his first name, Miles, was revealed (in The Spy Who Loved Me). Like his novel counterpart, he also has the rank of Vice Admiral and it is generally assumed that the M of the films and of Fleming's books are one and the same person.
