Ken Russell - Billion Dollar Brain (1967)

Harry Palmer no longer spies for the British and is instead a starving private detective. He receives a package of money which is followed by a mechanical voice that gives him his instructions over the phone. He accepts the assignment and finds that he has entered the world of a Texas Billionaire who thinks he can bring about a popular uprising in the Soviet Union with the help of a highly sophisticated computer.

The third in the Harry Palmer trio of spy movies, BDB is a "tour de force" of imagery, sound and acting talent. Directed by Ken Russell, this is one of the few examples of art film combined with commercial film production. The cinematography is superb with atmospheric footage shot in Finland (expensive), stunning studio sets including the computer room belong to megalomaniac General Midwinter and an end sequence which is both very graphic and impressive.
