With the hills and bridges of San Francisco as a backdrop for a suspenseful kidnap-extortion drama, Experiment in Terror is rivaled only by the 1978 Invasion of the Body Snatchers for its suggestion that behind the graceful facade of this city there lurks something ugly and malevolent. By day, Lee Remick and Glenn Ford are convincing, empathetic normals named Kelly and Rip, a bank teller and FBI agent, respectively. But at night, Remick is the victim, via the miracle of the telephone, of an asthmatic psychopath (Ross Martin) who vows to kidnap her younger sister if she doesn't meet his demand for money from the bank. Sis can't know of the plot, so the masquerade continues. Henry Mancini's score is effectively edited in to manipulate the real victims of this nightmare--the audience--and director Blake Edwards seems to delight in heightening the epic Americanism of his small tale, whose villain, with the doubly evocative name of Red Lynch, meets with sudden death on the pitcher's mound at Candlestick Park.
