Here is one, Fritz the Cat, one of the best INDEPENDENT animation movie in history of cinema!
Fritz the Cat is a 1972 American adult animated comedy film written and directed by Ralph Bakshi. It was Bakshi’s feature film debut and is loosely based on the Fritz the Cat comic strips by Robert Crumb. It was the first animated feature film to receive an X rating in the United States.
The film stars Fritz (voiced by Skip Hinnant), an anthropomorphic cat in mid-1960s New York City who explores the ideals of hedonism and sociopolitical consciousness. The film is a satire focusing on American college life of the era, race relations, the free love movement, and left- and right-wing politics.
