美国著名类型电影研究学者汤姆斯.雪兹说,只有极少数的电影故事因其独特的社会和美学特质,才能被改良为“公式”。所以类型不是凭空产生的,它的产生和持久存在有着内在的文化原因。类型通过对成功模式的重复可以降低市场风险、强化所表述的特定文化含义,但类型的形成往往要经历一个漫长的演变过程。 Thomas Snow, the famous American film research scholar, said only a handful of movie stories can be modified into “formulas” because of their unique social and aesthetic qualities. So the type is not created out of thin air, it has inherent cultural reasons for its production and lasting existence. By repeating the pattern of success, the type can reduce the market risk and reinforce the specific cultural meanings expressed. However, the formation of the type tends to go through a long process of evolution.
