Mutant/Night Shadows is a film with a small reputation, although it has not been widely seen. Part of the problem was Edward L. Montoro, an exploitation producer who ran Film Ventures International. Montoro had made a number of films including Grizzly (1976), Day of the Animals (1977), Dont Go in the House (1979) and the US versions of several Italian films such as Beyond the Door (1974), Anthropophagus (1980) and Shark (1982). At the time Mutant came out, Montoro was caught up in a host of lawsuits and a divorce settlement, which would have entitled his wife to half the ownership of Film Ventures, whereupon he vanished with several million dollars of profit. Intriguingly, he has never been heard from since, believed to have fled to South America.
Mutant is an interesting and worthwhile genre item, even if it is not fully successful at what it does. John Bud Cardos creates an effective atmosphere of Southern smalltown bigotry bristling at the intrusion of outsiders the film's redneck tensions and prejudice that stand only a few steps up the civilised ladder from Deliverance (1972). Cardos generates some out of the blue scares particularly good is one scene where Lee Montgomery settles into his room at the boarding house for the night, hears scraping noises and looks under the bed to see what is there, only to be grabbed and dragged under by something unseen.
The film works particularly well in its build-up with the mix that Cardos creates of redneck tensions, the mystery about what is happening and constant strangeness of things in the town. In fact, it is not until the 57-minute mark that we actually see any zombies at all. Clearly, the film has been inspired by and intended to play into the 1980s fad for zombie movies that came out after the success of Dawn of the Dead (1979). When it eventually arrives at such, Mutant throws nothing of any particular originality or distinction into the pot. The gore effects expected of the genre have been tamed way down. The zombies are run of the mill - certainly their emergence is nowhere as interesting as the build-up that Cardos generates. (Part of the problem with this is that the film has a script that started out as a plague outbreak drama that was retooled to turn into a toxic waste zombie film). The film arrives at an okay apocalyptic eruption around the town with Wings Hauser locked into a cellar with Mary Nell Santacroces zombie daughter, Jody Medford surrounded in a car, she venturing into the school to rescue Cary Guffey, and her and Wings Hauser running through the streets.
The film is also well served by an interesting cast. Having known Wings Hauser for the numerous bad guy and psycho roles he played throughout the 1980s and 90s, it is unusual seeing him here, much younger and playing the heroic lead. Bo Hopkins does well, giving a wry flinty performance as the sheriff the sort of role that Wings Hauser would specialise in himself a few years later. As the kid brother who disappears early in the show, is Lee [Harcourt] Montgomery who had a minor genre career as a child actor in films like Ben (1972), Burnt Offerings (1976) and Dead of Night (1977), and by this time is all grown up and making for an incredibly handsome lead. Unfortunately for Montgomery, he disappeared from acting not longer after Mutant was released and these days apparently works as a musician. Another child actor of interest is Cary Guffey who played the abducted kid in Steven Spielbergs Close Encounters of the Third Kind (1977), did less than half-a-dozen roles and likewise has never been heard from again.
