The seventies saw a minor boom in creature feature films after the box office success of Jaws. Hence, we had movies such as Orca (1977), Tentacles (1977), The Pack (1977) and Piranha (1978). If an animal could eat you or potentially pose any threat to people, someone somewhere would make a movie about it. Usually a bad one. A few of these even dared to stray into other hot topics of the time such as pollution and protecting the environment. Some would even invoke mysticism and folk lore to facilitate their protagonists. Nightwing is one such curious genre hybrid which combines vampire bats, shale oil mining and Native American culture in its clumsy and unsubtle plot. It’s a somewhat odd undertaking, directed by Arthur Hiller. His previous work included Love Story (1970) and Silver Streak (1976), so he was not the first person you’d expect to see associated with such material. The film doesn’t work well as either a horror movie or an exploration of social issues, but like so many movies from this era, it is of interest mainly due to its sheer incongruity.
