sent it back saying they just base it on what they feel in the room at the time. And we had like eight or ten films in there, like The Omen where the guy gets his head cut off by the sheet of glass, and it didn't matter to them." Craven had a hand in selecting Bruce Joel Rubin to write the screenplay for Deadly Friend. Rubin agreed with Craven that the film should have a gentler tone than his other features. Craven couldn't write the script himself because he was directing episodes of The Twilight Zone at the time. Craven and producer Robert M. Sherman hired Rubin as the screenwriter because they read his script for Jacob's Ladder, which was unproduced at the time. For the scene chronicling the transplant of BB's microchip into Samantha's brain, Craven called on the advice of retired neurosurgeon William H. Faeth, who has a cameo in the film as a coroner in Sam's hospital room. Craven said that he was very helpful on all the anatomical details. The robot, BB, cost over $20,000 to build. Craven used a company called Robotics 21. His eyes were constructed from two 1950's camera lenses, a garage remote control unit, and a radio antenna taken from a Corvette. BB could actually lift 7,500 pounds in weight. The voice of BB was provided by Charles Fleischer, who appeared in Wes Craven's previous film A Nightmare on Elm Street as a doctor.

Also, according to Swanson in a 1987 interview with Fangoria writer Mark Shapiro, "Craven suggested that I take a look at the movie Starman because what he wanted to do with Deadly Friend was similar in tone to that film." John Carpenter directed Starman because he wanted to get away from his reputation as a director of violent films, just like Wes Craven wanted to make Deadly Friend with a PG rating in mind so he could prove that he could make a film that was not simply "blood and guts" horror. Post-production According to the book Wes Craven: The Art of Horror by John Kenneth Muir, Craven's original cut of the film was "a teenage film filled with charm, wit, and solid performances by likeable teens
