Gold's Macbeth

The movie was very interesting and more entertaining than simply reading the words from a page because the individual actor's interpretation and ability to add their own style. The stubble element of theater performance and experience on the screen allowed all of the actors to do excellent jobs. one seen that I thought was really well done and thought deserved to be analyzed was the infamous banquet scene done in this movie. First off, the scene starts with an incredible heavy tension in the air due to this being recent after the previous king Duncan was murdered. By this point everyone has figured out it was him and are too afraid to do anything about it since he is the king and he is an excellent warrior. The muse-en-scène revolved around the table and the massive self portrait, reinforcing the ideas of dictatorship, isolation due to the lack of common citizens or servants, and celebration due to the props being used to express the idea that this feast is something to celebrate. the fact that the lighting changed dramatically every time the ghost of Banquo appeared created a sense of fear and unholiness. This is also done with the ghost by using the lighting to show off only his outline, leaving the rest of his body in a shadow. This use of backlighting and use a low angle shot to make the entire ghost and his blood covered body appear larger and more formidable that it actually is. Another element in creating this scent hat i noticed was the very obvious but well used diegentic elements like the harsh music that plays along with the sound effects when the ghost appears to create a even more powerful idea of fear. The fact that the ghost itself is a diegentic element that only Macbeth can see also the image of Macbeth losing his mind and that reinforces the ideas of absolute power corrupts absolutely and that guilt and evil deeds such as murder will haunt the murders for the rest of their lives. 

My questions:

What other diegentic elements are played in this scene and how do they effect the interpretation of scene to the view? Do these elects help or hinder the deliverance of the message during the scene? also, do common practical mistakes such as over or underacting or bad lighting throw of the impact of the scene or the dialogue?
