What are the responsibilities and division of labor of directors, producers and producers?

First of all, what is the director probably doing? Do you have a basic concept? Everyone knows that he is the main creator, and the division of work such as screenwriter, actor, photography and editing all serves his creation (of course, in an ideal state, all technical departments are also engaged in artistic creation). Let me talk about the specific implementation methods in the studio and production period. Forget casting. ? For the screenwriter, the director should examine the feasibility and coherence of the plot written by the screenwriter and turn it into a narrative composition form with a sense of picture (so it is best to draw a shot in person. Everyone has seen the comparison between Jiang Wen and Tsui Hark. Some directors who lack painting skills and composition ideas will hire someone to paint a scene, and then judge whether the lines written by the screenwriter meet the needs of the role and the plot. Most directors will personally modify the specific lines on the set (some actors who are good at improvisation will also modify them, provided that. ? For photography (photography guidance), the director should provide specific requirements such as lens composition, scene requirements and lens length. Then the photography director and camera photography will take the whole scene (the whole lens) requested by the director. Some directors with photographic background, such as Zhang Yimou, occasionally take the lens in person, while most directors just stay in front of the monitor to see the shooting effect. Like Quentin, the director of Wild Road Fans always makes inferences (I want a shot of a certain scene of a movie), claiming that he can only direct but can't shoot (that is, he won't shoot a bunch of materials in the same scene and then pick them out in the editing room). ? For actors, the director should tell their stories and explain what emotions, eyes, expressions and tone the actors will use to perform (walking, lines and body movements) in a scene or shot to be performed next. Most directors will put forward clear performance requirements or tell the actors the true state of their roles, while some directors from actor backgrounds, such as Jiang Wen, will not give actors too many rules to play freely. A few directors who are particularly good at directing actors' performances, such as Ang Lee, will directly make demonstration suggestions (this is also an important reason why a bad actor Rainbow Leehom can barely pass the test, and an actor like Zhang Ziyi who is not suitable for Yu Jiaolong can also perform brilliantly).
