I Saw What You Did is a 1988 American made-for-television horror film directed by Fred Walton, with a screenplay by Cynthia Cidre. It is a remake of the 1965 theatrical film of the same name starring Joan Crawford, and the second adaptation of Out of the Dark by Ursula Curtiss. The film stars Shawnee Smith and Tammy Lauren as teenage friends Kim Fielding and Lisa Harris, respectively, and Candace Cameron as Kim's younger sister Julie; opposite them is Robert Carradine as the mentally disturbed Adrian Lancer, and David Carradine as his brother Stephen. While making prank phone calls pretending to know who the other person is, and what they've done, Kim and Lisa call Adrian, who has recently murdered his girlfriend, causing him to set out to find them.

Casting for the film began in May 1987, with most of the principal actors — Smith, Lauren, and the Carradine brothers — being cast in June. Filming began that same month in various locations in Los Angeles. Upon its premiere on CBS on May 20, 1988, the film was the second most-viewed program at the time of its airing. It received mixed reviews from critics. Nevertheless, it won a Primetime Emmy Award for Outstanding Cinematography for a Miniseries or a Special.
