The impressive two and a half minute crane shot the encircles Tilda's house took three days to be completed. American distributors wanted the shot to be cut from the film for US release, but Argento refused.
The background "muzak" theme playing in the department store at the beginning of the film is taken from the soundtrack of the European version of George Romero's Dawn of the Dead (1978) (which was edited and re-scored under Dario Argento's supervision).

In an interview that appeared in Cinefantastique, Dario Argento noted that the film was intended as near-science fiction, taking place "about five or more years in the future ... Tenebre (1982) occurs in a world inhabited by fewer people with the result that the remainder are wealthier and less crowded. Something has happened to make it that way but no one remembers, or wants to remember ... It isn't exactly my Blade Runner (1982), of course, but nevertheless a step into the world of tomorrow. If you watch the film with this perspective in mind, it will become very apparent." Argento later insisted that the film was set in an imaginary city, fifteen years in the future, and that the disaster the city's inhabitants were striving to forget was an atomic bomb blast.
