(Personal opinion deleted.)
Close up shots of women breasts (at least a dozen different women) at different times in the movie.
Sex scene where a very young woman is having her breast squeezed by an old man. Nudity shown.
Women getting undressed while facing multiple men while they photograph her- in slow motion. Full frontal extend female nudity with close ups on breast, butts, and vaginas.
The movie contains several minutes of non-erotic nudity, mostly adult men and women in profile, in various activities: walking, running, jumping over a chair, etc. These moments occur when the film shows Muybridge photographing these people multiple times during their movement. His intent was to document factually how the human body moves. Breasts are prominently visible; male genitalia are slightly visible and female genitalia is graphically shown.
