Rescued from garbage cans, shoeboxes and garage sales, Cinematheque tonight presents an eclectic assortment of “found” film footage, including obscure narratives, early music “videos,” political  treatises, television com­mercials, sexploitation, educational,  industrial and other filmic oddities. “Slug” is the movie industry’s term for footage considered “throwaway” and unusable due to some error; many of these films were never intended for theatrical viewing, but were specifically created for other contexts — as interruptions to tv programs, backgrounds to burlesque revues, as instruc­tional and propaganda aids in classrooms and on the job. SlugFest will unleash a sumptuous smorgasbord of images and sound that create an inadvertent,  metaphor-laden refabrication of 20th century human culture. Programmed by Scott Stark and Robert Fox.
