Lost Atlantis (1921)

Two topless women are in a scene briefly. For most of the time only their bare backs are visible, but at a certain point one of the woman's breasts are very briefly visible for a second at most.

Several young boys play in a body of water in the nude. In a very brief close up shot gentiles are noticeable, although it's more like a silhouette in appearance, and of course very brief.

In the second half of the movie, several women wear revealing clothing. Although none appear to expose any overt nudity, several show ample cleavage and exposed sides of breasts.

A major theme of the film is about a woman seducing men, although this is portrayed very mildly.

A man is killed with an ax. This is only shown through a shadow, although the bloody aftermath is shown. In addition, it takes a little while for the man to die.

Occasional smoking. In one case a woman tricks a man into smoking what appears to be some kind of hallucinogenic drug.

A city is raided by several men and burned. The women are forcefully carried away and are forced to walk across the desert.

A man and women struggle to walk through a desert with little, and eventually no water.
