In this thriller from Blake Edwards (Breakfast at Tiffany's), Glenn Ford   plays an F.B.I. agent assigned to protect two sisters (Lee Remick and            Stephanie Powers) menaced by an asthmatic psychopath, creepily played by Ross    Martin. Ford plans an elaborate set-up to capture the heavy-breathing fiend,   but it goes awry, resulting in the film's memorable climax in San Francisco's  crowded Candlestick Park.                                                      Blake Edwards---USA---1962---123 mins.
