While the other two avant garde short films in this month's Potluck Film Festival have had an enduring influence on mainstream cinema for several decades, Peter Tscherkassky's Outer Space — the second chapter in his Cinemascope Trilogy — works in the opposite direction, fashioning something new out of an existing commercial feature. In Sidney J. Furie's arguably exploitative 1982 horror movie The Entity, a woman (Barbara Hershey) is repeatedly assaulted by an unseen force. In a fearsome 10-minute burst, Tscherkassky repurposes The Entity with heavy optical processing to produce a startling meta-horror: in his version, it appears as if Hershey is being stalked and attacked by the very act of filmmaking, or even film itself. Whether Tscherkassky intends this as a comment on the misogynistic nature of horror, or movies in general, it's a viscerally bracing experiment that lashes out at the audience, as well, with its potentially seizure-inducing pulses of high contrast frames. It's disturbing and impactful, with compelling visual effects.
