What are the artistic techniques in Hollywood movies?

They take a technical route, mostly commercial films. These movies all have the same pattern. The story structure first constructs contradictions, then develops contradictions, and finally solves contradictions. It's very simple, so these films don't use some unique artistic techniques, but play with technology, high-end audio-visual technology, realistic computer stunts, cool lens expression, bold imaginary scenes, and mostly cheerful rhythms. Generally speaking, these films do not express lofty themes, but only show some entertainment. Mainly entertainment function. Generally, unlike China's films, they are all social and realistic, and they want to express some repressed thoughts. It is just a carrier of entertainment, and its function is different from ours. Therefore, most stories are fictional, and the actors are mostly handsome and beautiful, and they play handsome and cool in them. I prefer to use montage techniques, such as montage of narrative voice, and I like to make a fuss about inciting the audience's emotions, such as lengthening time and space and narrative, stimulating people's appetite, and trying to be sensational in performance. They have technical advantages in photography, mostly because the content inside is super beautiful, super fictional, and the composition is generally rigorous, which makes people look comfortable. Other artists and props lighting have technical advantages, all in order to make the camera have super audition shock. What I said is just a general idea. You should pay attention to it yourself in the future. Of course, this only refers to those commercial films. There is no shortage of art films in Hollywood. Those are another matter.
