Overview
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.
Plot
Lisa Harris, a popular high school student who is more interested in her boyfriend Louis than getting good grades, is invited to dinner by Kim Fielding, her intelligent classmate who never breaks any rules and has to babysit her sister Julia, since her father is out of town for the night. Feeling she has nothing in common with Kim, Lisa only agrees to come over to meet her boyfriend Louis there. Bored at awaiting his arrival, she joins Kim and Julia in making prank calls. When it's her turn, Lisa calls Adrian Lancer, a man with mental problems who just murdered his girlfriend Robyn Griffin for declining his marriage proposal. Lisa decides to hang up, and later calls people, saying, "I saw what you did, and I know who you are", before hanging up.
Later, Lisa and Kim discuss Kim's love life, deciding she needs an older man who appreciates her. They decide to call Adrian again, but Lisa, afraid to seduce him, repeats the line, "I saw what you did, and I know who you are." Adrian, who was caught in the act when burying Robyn's body, does not realize it's a prank, and is determined to get rid of her. Kim, thinking he was flirting with her, calls him again later, agreeing to meet with him.
