Compared with the traditional German advanced audiovisual class which mainly relies on the textbook, the classroom atmosphere of the movie class is more active, the students' motivation and learning efficiency are higher. Unlike the modified and unnatural language of textbooks, the more realistic language of movies can better train students' listening skills in real contexts. In addition, movies can show the non-verbal communication between speakers, which has stronger cross-cultural communication function. Teachers must choose appropriate films, prepare their lessons well and organize their teaching in a scientific and rational manner in order to teach students general foreign language skills, culturally sensitive knowledge and competence, and film literacy, to enhance students' language skills in the five areas of watching, listening, speaking, reading and writing, and to improve students' cross-cultural communication skills, humanistic literacy, and appreciation of film and television.
