Enjoyable, one-box-of-popcorn thriller
2 August 2002 | by (las vegas, nv) – See all my reviews

Kids left alone in the house inadvertently play a phone prank on psychopath John Ireland, who has just murdered his trampy Mrs. in the shower! Whenever you see a biography of Joan Crawford's career, this title usually gets left out. True, she has a minor role in it (playing Ireland's neighbor, hoping to blackmail him into marriage), however it's one of the better movies she was involved in after "What Ever Happened to Baby Jane?" William Castle did a good job as producer/director of this story, and the two teenage girls are very appealing and natural. The movie builds some credible suspense (underlined with a jokey tone) and has interesting visual tricks and groovy music. Avoid the awful, too-literal 1988 TV-remake. **1/2 from ****
