Audrey Hepburn's last Oscar nomination was for this adaptation of Frederick Knott's famed stage thriller about a blind woman, a con man (Alan Arkin), and a doll full of heroin. Thanks to Hepburn's husband, a photographer who does a good deal of traveling, she's unknowingly come into possession of said doll, which was given to him on a plane by a comely young drug runner who winds up dead. The murderous Arkin, aided by sympathetic henchman Richard Crenna, will let nothing stand in the way of his obtaining it, even if it comes down to assaying multiple "personalities" in order to visit and terrorize Hepburn; Crenna is unwillingly enlisted to help. However, the "world's champion blind lady" (as Hepburn sardonically states) is more than up to the task of defending herself in her basement Manhattan apartment in a heart-stopping climax that to this day still defines the way horror movies with jack-in-the-box psychos are made. Despite the obvious staginess of it all (the entire action takes place in Hepburn's apartment), it still works magnificently, thanks to Hepburn's steely will and Arkin's deadly, sadistic madman. A helpful hint: turn out all the lights when you watch it; theaters back in 1967 did so, killing the guiding lights during the film's last 15 minutes. We can't tell you why, but trust us, it's worth it. --Mark Englehart
