性一直是电影中一个重要的表现主题,然而在不同的时期由于受到政治、宗教、道德宽容度等原因的影响,导演们对这一主题的重视程度以及表现尺度是不同的。统计表明,20世纪70年代,美国电影中表现性这一主题的表品急剧增加,与之前形成了鲜明的对比。“性解放运动”的爆发,文化的后现代转向以及电影体的变都是导致这一现象出现的原因。 Sex has always been an important theme in the movie. However, due to political, religious, moral tolerance and other factors at different periods, directors pay more attention to this topic and have different performance scales. Statistics show that in the 1970s there was a dramatic increase in the number of articles on the subject of expressiveness in American cinema, in stark contrast to the previous one. The outbreak of “sexual liberation movement”, the postmodern turn of culture and the change of the movie body are the causes of this phenomenon.
