Macbeth’s head should be very detailed. The head should have sweat still streaming from it and have many scars. Macduff should be gripping it tightly by the hair, as if he hasn’t let go since he killed Macbeth. Macduff should raise it into the air as the Scots hail the new king.
For Macbeth: After he slays Siward the camera should show his face and he should have a ruthless look. His teeth should be barred and he should be squinting. He should look as intimidating as possible. This is one last look at how off-the-rails Macbeth is.
The men are in front of the castle, about 100 feet. The only thing in between them and entrance is a large drawbridge. This is to make Macbeth seem close, but still a challenge. Macbeth murdered Duncan in a small tent, by himself. Malcolm and Macduff have a large army and a huge castle to compare against Macbeth’s deed.
As Macbeth is hearing the news of trees moving the camera will shift. The first position is a place above the castle, with courtyards in view. In this position the audience will see the trees swaying and moving forward. When Macbeth says “‘Fear not, till Birnam Wood…'”, the camera will zoom in and make all of the soldiers visible. This will show how much force is approaching.
Malcolm orders his me to cut branches to camouflage themselves. Most of them will appear to have the branches tied to them and stuck in various kinks of armor. Macduff will have pieces of bark attached to his chest piece and his helmet. He will do this to stand out and grab the audiences attention. He will swing his sword and make sure that the wood does not constrict his movement.
Macbeth’s armor should be black and tightly fitting to his body. The black is to make him look sinister and create more of an impact when he tells Seyton to get his armor. It should fit him tightly because he has been preparing for this fight and he is very well tested in battle.
For the soldiers: I want them to be shouting or singing. In Les Miserables , the French rebels sing as they march down the streets. The soldiers should be excited to rid Scotland of Macbeth and start a new era. They should be a very organized force, to contrast how broken Macbeth is.
(My comparison to Les Miserables may be wrong, I’ve only seen a single scene)
