Abstract: Wild Hunter was released in 2015. The film, directed by Arizona Drew, Sam Zarez and Inarido, was shot in the western United States in the 19th century. It tells the story of Ras, a fur hunter, who was seriously injured by a bear and struggled to survive in a difficult environment. The plot of the film is not complicated, the character setting is simple, and the narrative rhythm is relatively slow, but it can arouse the audience's strong emotional and cognitive experience, which is impressive. The film's lens language is simple and has a strong documentary style. At the same time, through the control of unique scenery, angle and rhythm, the film creator properly sets off the complex inner world of the characters and gives the film a romantic and poetic atmosphere. Based on the background of this research topic, this paper introduces the historical narrative and image expression under the long lens of Wild Hunter, and finally outlines the use of long lens in the film, hoping to have a deeper understanding of the use of long lens in the film.
