Hypocrites, Lois Weber (1915)

"Hypocrites, also known as The Hypocrites and The Naked Truth, is a 1915 silent drama film written and directed by Lois Weber. The film contains several full nude scenes, and is said to include the first appearance of full frontal nudity in a non-pornographic film by an American actress. The film is regarded as anticlerical, and the nudity was justified by its religious context."
