Trailer for the 1967 classic Billion Dollar Brain.
Noted British TV director Ken Russell oversees this third installment of the Harry Palmer series. No longer working for the British Secret Service, Palmer (Michael Caine) has become a private investigator, and has been hired to travel to Latvia to visit an unknown doctor. There, he meets none other than his old friend Leo Newbigen (Karl Malden), who introduces Palmer to his new line of work. Palmer, of course, senses something amiss, and wastes no time tracking it down. He soon finds himself embroiled in the plans of a megalomaniac Texas billionaire, General Midwinter (Ed Begley), to take over the world with a computer the size of a football field--the "brain" of the title.
