Earthlings is a 2005 American documentary film about humanity’s use of other animals as pets, food, clothing, entertainment, and for scientific research. 
The film is narrated by Joaquin Phoenix, features music by Moby, was directed by Shaun Monson, and was co-produced by Maggie Q, all of whom are practicing vegans.
 Covering pet stores, puppy mills, and animal profession, Earthlings includes footage obtained through the use of hidden cameras to chronicle the day-to-day practices of some of the largest industries in the world, all of which rely on animals. It draws parallels between racism, sexism, and speciesism. 

This film is about cruelty to animals. Caution advised! 
Cruelty to animals, also called animal abuse or animal neglect, is the human infliction of suffering or harm upon non-human animals, for purposes other than self-defense or survival. More narrowly, it can be the causing of harm or suffering for specific gain, such as killing animals for food or for their fur; opinions differ about the extent of cruelty associated with a given method of slaughter. Cruelty to animals sometimes encompasses inflicting harm or suffering for personal amusement, as in zoosadism.
