Billion Dollar Brain is a 1967 British espionage film directed by Ken Russell and based on the novel
Billion-Dollar Brain by Len Deighton.
The film features Michael Caine as secret agent Harry Palmer, the anti-hero protagonist of the film versions
of The IPCRESS File (1965) and Funeral in Berlin (1966). The “brain” of the title is a sophisticated
computer with which an ultra-right-wing organization controls its worldwide anti-Soviet spy network.
The glittering “Main Title” brilliantly accompanies Maurice Binder’s title sequence inspired by 1960s
supercomputer operations. Like Bernard Herrmann, Bennett achieves remarkably epic and varied sonorities with minimal forces, orchestrating the music himself.
