If reality has been supplanted by the image, then violent acts can be seen as the retrieval of a lost authenticity. Johan Grimonprez shows us one spasmodic attempt at reality recovery, the airline hijacking, and throws in a mini-history of the revolutionary impulse as well. Assembled from newsreel footage of skyjackings and their gruesome aftermaths, Grimonprez's pseudo-documentary concentrates on the glorious double decade of the sixties and seventies when violent assaults were as predictable as lost luggage. Grimonprez culls the writings of novelist Don DeLillo for the intermittent flight announcements. Shown with Big Day Off (David Janssen, U.S., 1997, 13 mins), about the dubious benefits of vacation time in the technologized future. And Signing Off (Robert Sarkies, New Zealand, 1997, 15 mins), a grimly hilarious tale about a retiring DJ who'll do anything for the record.-Steve Seid
