The plot and theme of the film are unique, but it is insignificant compared with the film’s attempts in film technology. The film is a bold experiment by Hitchcock. He has made unprecedented attempts at the use and effects of long shots, and the entire film almost does not need to be edited, which also breaks the rules of montage. At the end of the film, Rupert's analysis of the case reflects the exploratory nature of the long shot. It makes the transition of the film from the details to the entire scene have a relatively complete logical relationship between time and space.
"Imperial Soul" is an adventurous work. In the film, Alfred Hitchcock's control capabilities in scene scheduling, actor performance, camera movement, and color lighting are fully demonstrated. Although the film did not get the results of film theory, this brave experiment has left a touch of color in the history of film because of Hitchcock's wisdom and exploration spirit.
"Imperial Soul" is an alternative work in a thriller movie, it relies on the lens and dialogue to create an effect. This work does not use any traditional rendering techniques. There are no jumps and fluctuations in the film from narration to editing. At the beginning of the film, the entire murder process was clearly shown to the audience by the director. This is a frontal lens with no hidden traces at all, but the visual impact is extremely strong. Another weirdness of the film is that it exposes the same psychology between the murderer and the murderer, which is also something that the audience should think about. ()
