Alfred Hitchock's 1966 geo-political thriller opens with two big box-office stars canoodling in bed. At a physicists' conference, no less! Paul Newman is Professor Armstrong, an American atomic egghead so desirable that he has won the attentions of more than just his brainy assistant and bed-mate Sarah (Julie Andrews); he's defecting to East Berlin to help the Soviet Bloc with their weapons program. Sarah secretly follows Armstrong to East Germany, where everybody's true loyalties will be tested. The film suffers somewhat from a dated Cold War plot, and the two stars seem less than ideally cast, but fans will savor several classic Hitchcock tension-filled escape scenarios.
