Echoing the canine theme of the new Mexican hit Amores Perros, Bong Joon-ho’s Barking Dogs Never Bite is a dark, twisted comedy about a deadbeat college lecturer who becomes obsessed with the relentless yapping of a neighbor’s pooch — and sets out to silence the animal once and for all. Set in a high-rise Seoul apartment building, the film is one of several canicidal tales featured in this year’s festival.
