List of James Bond allies in You Only Live Twice

Following is a list of recurring and notable allies of James Bond who appear throughout the film series and novels.

M is a Rear Admiral of Royal Navy and the head of the Secret Intelligence Service. Fleming based the character on a number of people he knew who commanded sections of British intelligence. M has appeared in the novels by Fleming and seven continuation authors, as well as 24 films. M has been portrayed by Bernard Lee, Robert Brown, Judi Dench, Ralph Fiennes, John Huston and Edward Fox.

Miss Moneypenny is the secretary to M. The films depict her as having a reserved romantic interest in Bond, although Fleming's novels do not imply such a relationship while the John Gardner and Raymond Benson novels emphasise it more. In the film series, Moneypenny has been portrayed by Lois Maxwell, Barbara Bouchet, Pamela Salem, Caroline Bliss, Samantha Bond and Naomie Harris.

Q (standing for Quartermaster), like M, is the head of Q Branch (or later Q Division), the fictional research and development division of the British Secret Service. His real name is Major Boothroyd, but Bond and M never use his name. He has appeared in 20 of 23 Eon Bond films; all except Live and Let Die, Casino Royale and Quantum of Solace. The character was also featured in the non-Eon Bond films Casino Royale (1967) and Never Say Never Again. He has been portrayed by Desmond Llewelyn for most of the films, but has also been portrayed by Peter Burton, Geoffrey Bayldon, Alec McCowen, John Cleese (who is credited as R), and Ben Whishaw.
