One scene that lasts nearly a minute shows an 11-year-old boy masturbating
Judging by the outraged reaction to Cuties, it might be supposed that this movie breaks new ground in the acceptance of child sexuality in the movies. Older heretics will know better. The poster [see article] is for a 1980 Swedish film, Children's Island (Barnens ö). One scene that lasts nearly a minute shows an 11-year-old boy masturbating. This includes several seconds with a full frontal shot of his erect penis. The film won Sweden's top film prize. On a visit to Norway, I saw it in a packed cinema in Oslo, where there were plenty of apparently respectable, parent-age couples in the audience who showed not the slightest sign of shock or disapproval.
