Two silly teenagers (Andi Garrett, Sara Lane) left to their own devices make random prank calls to anonymous strangers whose names they find in the phone book and tell them, "I saw what you did and I know who you are". But it's more than a prank to one man (John Ireland) who's just murdered his wife (Joyce Meadows). Yes, director William Castle (STRAIT JACKET) is up to his old tricks again. Between the awful acting of the two teen leads and the annoying kid sister (Sharyl Locke) and the Brady Bunch underscore, it's hard to take the movie seriously. Throw in the 60 year old Joan Crawford (who looks a decade older) acting like a kittenish femme fatale, you have an irresistible groaner of a movie. The premise itself is good but it would take a better script and a director who took his work more seriously (thankfully, he was talked out of directing ROSEMARY'S BABY) for it to fall into place. But he was a showman all right! The posters warned "This is a motion picture about UXORICIDE!" which no doubt sent moviegoers to their dictionary. With Leif Erickson, Patricia Breslin and John Archer.
