Shot in two weeks for just $30,000, this paranoid pot romance—which is also an urban-guerrilla comedy—is pleasantly disorienting. First it's about a couple of burned-out radicals. Then it's about a siren with easy access to huge amounts of marijuana. Then it's about a pack of bicycle anarchists and a Molotov cocktail. Monkey Warfare is a Canadian movie, but it looks and feels dirtier and sexier than you thought contemporary Canadian cinema could be. (Harvard Exit, 807 E Roy St, 324-9996. 2 pm, $10.)
