Earthlings (2005)

A documentary by the American environmental organization Nation Earth seeks to show the brutality that humans inflict on animals in order to make viewers rethink their lifestyles. It is divided into several parts: pets (trapping and extermination of feral dogs), food (torture and slaughter of livestock in slaughterhouses), clothing (killing animals for fur), entertainment (cruel living conditions of animals in circuses, death in rodeos and in bullfights). The film is actually a narrated series of individual shots, most of which are allegedly taken by hidden camera in real slaughterhouses and similar places.
