LONG WEEKEND (1978)
Nature activity: Camping
Natural disaster: Nature's animal army attacks and unnerves an obnoxious Australian couple with a Godzilla-sized carbon footprint for offenses like discarding cigarette butts in dry brush, spraying insecticide on ants, and stealing eagle eggs.
Complex says: If there are no "Give a hoot, don't pollute!" signs, how the hell are we supposed to know we shouldn't start a brushfire?
