Anthony King looks at Macbeth as a PTSD sufferer:
Although the descriptions are graphic, Shakespeare’s play itself includes few on-stage battle scenes. Only at the very end does Macbeth actually fight on stage, a last stand in which he kills the young Siward (his last victim) and is in turn killed by MacDuff. For the rest of the play, all of Macbeth’s violence is set off stage, described but never seen. The audience imagines his violence — they do not witness it.
Justin Kurzel’s striking new adaptation of Macbeth, released on October 2, 2015 to critical acclaim and starring Marion Cotillard and Michael Fassbender, represents a cinematographic inversion of the original. In his film, battle predominates. The film begins with an extended combat sequence. Macbeth and his army are gathered on a bleak moor as they prepare for battle against Macdonaldwald’s army, unseen in the dense fog. The camera pans across the black-striped war-painted faces until, initiated by Macbeth, the host issues a war cry and plunges toward their enemies, who appear spectrally in the distance through the murk. In ultra-slow motion, the two armies clash and brutal fighting follows. Most notably, one of Macbeth’s boy soldiers, on whom the camera dwells tellingly before the battle, has his throat cut during the fighting and bleeds out darkly on screen. Eventually, Macbeth charges Macdonaldwald and slashes him to the ground. The scene is followed by a long sequence in which the dead are gathered and prepared for cremation, including the boy soldier, whose image haunts the rest of the film.
Macbeth’s apparently fearless heroism and remorseless violence is on display throughout these sequences. Yet the sequences highlight an aspect of Macbeth’s character normally absent from adaptations of the play and presumably from the original play, but highly relevant to a 21st-century audience. Macbeth is a combat veteran and, despite his courage, he is plainly severely traumatized by his war experiences. Kurzel and Fassbender construct him as a victim of PTSD, and he displays the classic symptoms of this perturbing condition.
