The Double Man is a 1967 British spy film directed by Franklin Schaffner. Its plot is very loosely based on the critically acclaimed 1958 novel Legacy of a Spy by Henry S. Maxfield. As in the novel, much of the action takes place in the Austrian Alps. The film stars Yul Brynner as a CIA agent investigating his son's fatal "accident": although he learns a few things from others, he slowly is convinced something else is happening and discovers a fiendish Russian plan.

Plot

During the Cold War a Russian intelligence officer tells an army general he has a plan to infiltrate the upper ranks of the American CIA. He assures the army general it cannot fail. The general approves the plan, but is skeptical and warns the intelligence officer of the fatal consequences should anything go wrong.
