English movies leaded by US and UK have cultural advantages, they reflect the powerful individualism and high-efficient perfectionism, that's the significant help for studying English culture, although it's so single-faceted. As an economic position, US movies usually use advanced techniques to make gorgeous and magnificent views, so they definitely have great box office, and that's an important step for going up the economic growth. In the view of students, they can learn many idioms,and as what I said above, movies can reflect the culture, so learners can also learn foreign culture and this is benefit for them to learn English.
