The film was originally entitled "Night of the Lepers" and about zombie-like lepers and a mass plague, riffing off the success of La notte dei morti viventi (1968). Unfortunately, the executive at MGM who first read the script was eating dinner and spilled wine on it, confusing "Leper" for "Lepus". When he joked to his teenage daughter about a film with killer rabbits, she loved the idea. The script writer was then commissioned to heavily edit the plot.
