During his acceptance speech for Best Actor at the 2020 Oscars, Joaquin Phoenix used his platform to make a national plea for animal rights. With the documentary “Gunda,” Phoenix puts his money where his mouth is. The documentary is an experimental black and white film about the life of farm animals that blew away audiences at this year’s Berlin Film Festival. “Gunda” challenges its viewers, by having them study animal consciousness and harmful the role that humans play in it.
