British Navy Commander James Bond, CMG, RNVR is a fictional character created by novelist Ian Fleming in 1953. He is the protagonist of the James Bond series of novels, films, comics and video games. He is portrayed as an SIS agent residing in London. From 1995 onwards, SIS would be officially acknowledged as MI6. Bond holds the code number 007, except for the novel You Only Live Twice, where he temporarily becomes "7777". The "double-0" prefix indicates his discretionary licence to kill in the performance of his duties. He is famous for introducing himself as "Bond, James Bond" and for ordering his vodka martinis "shaken, not stirred"; his usual and characteristic formal clothing is a dinner jacket. In the films he usually wears a Rolex Submariner watch or, in later films, an Omega Seamaster. He has been portrayed on film by Sean Connery, George Lazenby, Roger Moore, Timothy Dalton, Pierce Brosnan, and Daniel Craig, the last interpretation being the only one with an official fictional biography of the character.
