The character of Barbara is most likely a nod to the original Night of the Living Dead whose main character was named Barbara.
Black Summer was filmed in and around Calgary, Alberta, Canada. Some of the sets include the 1988 Winter Olympic Games facilities, Calgary Tower, and the Queen Elizabeth School. Other Alberta filming locations include the River Avenue Bridge over the Bow River in Cochrane and the rural towns of Irricana and Beiseker. In contrast, the show's sequel, Z Nation, was filmed in Spokane, Washington.
