In an interview, Silvana Gallardo (who played the housekeeper) said the rape scene was "grueling" and took about six days to film. To prepare for the role, she talked to an actual rape victim. She also said the actors who played the criminals raping her would immediately cover her up with a robe or blanket when the director yelled "CUT!"
Director Michael Winner once said of this movie: "From caveman days to today, there have always been violent times. You cannot say the Middle Ages weren't violent, before television or films. So where do you put the blame then - oil paintings and books?"
This movie upon theatrical release was marketed with Roman Numerals to signify the number 2 i.e. 'Death Wish II'. In time, its modern DVD releases tend to show the number two of the title as a numerical digit instead. This is then consistent with the titles Death Wish 3 (1985) and Death Wish 4: The Crackdown (1987). According to the book 'Bronson's Loose' by Paul Talbot, the original working title of the next film 'Death Wish III' was changed to 'Death Wish 3' because the Cannon Group conducted a survey and found that nearly half of the U.S. population could not read Roman numerals. Interestingly, the fifth film, Death Wish V: The Face of Death (1994), reverted to the use of Roman Numerals to signify the film number
In West Germany, this movie set a record for the number of video-cassette units sold. There, ten thousand tape sales of the home video were sold in two months thereby producing royalties of over $ 0.5 million in its first year on video-tape.
Film soundtrack was written by Jimmy Page, the former guitarist of Led Zeppelin. Page was the neighbour of director Michael Winner, who asked him to write the soundtrack for the film and Page recorded it only in six weeks.
The main gun Kersey uses (taken from the hidden compartment in his closet) is a Browning BDA .380, a 13 + 1 automatic made for Browning by Beretta from 1977 to 1997 and very similar to a Beretta Model 84 (same frame and magazine, different slide).
This movie was Charles Bronson's second consecutive picture to feature the word 'Death' in the title. Bronson's previous movie was Death Hunt (1981). Bronson made seven movies with this word in the title, five of them being in the 'Death Wish' franchise. Messenger of Death (1988) was another example. The final time would be in Death Wish V: The Face of Death (1994), where the word appeared twice.
