the exclamation point in the title be appropriate and albeit an understatement . this movie doesn not just cry it shriek loud enough to shatter glass . filmmaker andrew and virginia stone make shrill and humorless suspense thriller that strive for a semi documentary feel . here and they shoot on actual new york location with tinny real life acoustic to jack up the verisimilitude . but the naturalism of the sound record only serve to amplify the stone maladroit dialog and the mouth froth histrionics of tortured butterfly inger stevens . in a performance completely devoid of modulation and stevens play the wife of electronics whiz james mason ( look haggard and bore ) while both be hold captive by extortionist rod steiger ( look bloat and bore ) and his slimy cohort in a scheme to blackmail an airline with a deadly bomb that mason have unwittingly help construct . here be another credibility strain instance of a criminal mastermind so brilliantly attentive to every detail and yet knuckleheaded enough to hire a drug addict degenerate a an underling . the stones idea of nail biting tension be to trap the hysterical stevens alone with benzedrine pop rapist neville brand and fill the frame with his sweaty and drool kisser . but the camera work be so leaden and brand so ( uncharacteristically ) demure that the effect be hardly lurid and much less suspenseful . the stone and a square pair at heart and do not even have the courage of their own lack of conviction . the film and which end with the portly steiger chase the fleet foot stevens on a subway train track and be as clumsy a it ungainly heavy . with angie dickinson a steiger amoral girlfriend and jack klugman and kenneth tobey and and barney philip .
