Three Days of the Condor. Always use the back door. You never know, you may slip out for lunch one minute and return the next, pastrami and mustard in hand to find all your office mates spread across their desks, covered with blood. Meek and mild-mannered Robert Redford, who translates Russian novels for U.S. intelligence, came home to just such a spread, and leaving lunch aside, stepped into a phone booth and became "The Condor." The transformation is not complete--Redford is rather mild-mannered as a hero, too. When he calls into Central, he becomes a critical cog in the intelligence machine, but he spins a little out of synch. Trying to be his own man, Redford holes up in the apartment of a woman he kidnapped in a sporting goods store (didn't your always hope the man holding a gun in your back was Robert Redford?). Two world powers battle for the Condor, while he humps with a temperamental photographer. Once they catch up, Three Days of the Condor is a face-paced, carefully calculated thriller. Even Redford is convincing half the time.
