Some sex and nudity.
A couple kiss in bed. As they kiss, there is the hint of a thrust and some noises of pleasure from the young man and woman, whilst they are watched by another at the window. The sex scene is briefly repeated in flashback.
A young man is seen in his underwear and nightshirt for an extended period of time. He walks around his house and then outside in the street. His bare legs are seen.
A young man is seen in bed being treated for illness. He is unclothed and his bare chest is partially seen.
Some people embrace and kiss in a loving way. In once scene, a young man and woman kiss on the ground in a field. They start to unbutton their clothes. Later they are seen with their clothes unbuttoned, though nudity is limited to the man's bare chest. It is not clear if sex has taken place.
Some very mild medical nudity during the creation of Frankenstein's monster.
