Ken Russell's 1967 movie was the last in the original Harry Palmer trilogy, and it's lunatic great. Retired from MI5 and living on cornflakes as a flea-bitten private eye, Michael Caine's downbeat, kitchen-sink Bond has to deliver some eggs, and deal with a militaristic right-wing Texan oil baron who's planning to destroy Soviet Russia with his computer (the titular brain). Caine is quite brilliantly morose.
