Trivia

The movie's production notes, according to a review in The New York Times by Janet Maslin, stated that screenwriter Richard Rothstein went on vacation in Death Valley with friends and family. He saw a mysterious car approach his vehicle on "a lonely road in the middle of nowhere. What, he asked himself, if somebody bad were in that car and wanted to hurt me?". This actual real life scenario provided the inspiration for this picture.

Cybill Shepherd was considered for the role of Sally but the scheduling couldn't be worked out. In the end the part was cast with Catherine Hicks.

Then child actor Peter Billingsley received an 'introducing' credit despite the fact he had appeared in Paternidad (1981), Honky Tonk Freeway (1981), and If Ever I See You Again (1978).
