M (James Bond)

"If you carry a double-O number, it means you're licensed to kill, not get killed." ~ M played by Bernard Lee

"Effective Immediately, your licence to kill is revoked, and I require you to hand over your weapon.  Now.  I need hardly remind you that you're still bound by the Official Secrets Act." ~ M played by Robert Brown

"Well, I think you're a sexist, misogynist dinosaur.  A relic of the Cold War, whose boyish charms, though wasted on me, obviously appealed to that young woman I sent out to evaluate you." ~ M played by Judi Dench

M is the head of MI6 and the boss of James Bond from the James Bond film series.

He gives James Bond an assignment in each film except for "For Your Eyes Only" where he didn't appear in the film but he was mentioned by Bond and "Licence To Kill" where he revokes James Bond's weapon.

He is very strict about James Bond.
