A quasi-documentary about religious witchcraft, ranked 39th among the top 50 documentaries in the world. Introduction: Witches, also known as ancient witchcraft, can be regarded as a quasi-documentary about religious witchcraft. Between 19 19 and 192 1, Danish directors created this transcendental masterpiece co-produced by Sweden and Denmark, and played the role of the devil in the film. This film is novel in conception, superb in modeling skills and rigorous in picture structure, and it is very appropriate to use expressive close-ups and montage with strong sense of action. However, due to religious reasons, the film was banned by Sweden and other European countries at that time, and it was not until 1929 that a strictly edited version appeared in the United States. The director also moved to the United States because of Hollywood's slogan of accepting sages at that time, but it didn't succeed and he ended up depressed. The significance of this work lies not only in the sensitivity of the subject matter and the avant-garde technique, but also in the visual achievements. This film is undoubtedly one of the best in film history.
