There was a close relationship between literary classics and film adaptation. Film and television adaptation was usually to adapt the plot, characters, scenes and other elements of a literary work and construct a new story on this basis to meet the audience's entertainment needs. As a literary work, literary classics had a unique literary style, language use, character image and other elements. These were very important for film adaptation. In the process of adaptation, it was necessary to conduct in-depth research and analysis of classic literary works to ensure that the adapted film and television works could be comparable to the original and could better attract the attention of the audience. Film adaptation could also bring new forms of communication to literary works. In the process of film adaptation, the classic elements in literary works could be magnified and interpreted to attract more audiences. In addition, film and television adaptation could also bring a wider audience to the literary works and expand the influence of the works. However, there were also some problems with literary classics and film adaptation. As film and television adaptation required the reconstruction of the storyline, character images, etc., it might weaken or change the classic elements in the original work, thus affecting the reader's understanding and feelings of the work. In addition, due to the need to consider the audience's experience in film adaptation, it might lead to changes in the storyline and the exaggeration of the character's image, affecting the realism of the work. The relationship between literary classics and film adaptation was complementary. Literature classics could provide important inspiration and material for film and television adaptation, and film and television adaptation could also bring new forms of communication and influence to literary classics. Only by combining the two could they create better works to meet the dual needs of the audience for literature and entertainment.
