Corpus Callosum is a 2002 experimental Canadian film directed by Michael Snow. The title is a reference to the part of the brain which was once thought to have been home to the human soul, and which scientifically passes messages between the two hemispheres. The Corpus Callosum of the film refers to the mysterious space between illusion and reality. It won the Independent/Experimental Film and Video Award from the Los Angeles Film Critics Association Awards. Corpus Callosum is said to be a "digital self-appraisal of [Snow's] work", showcasing his passion for visual manipulations through editing. Throughout the film, Snow's voice can be heard as he directs the film, adding to the break in the fourth wall which the film attempts to create.

Plot

Office workers go about their day-to-day business, all while their surroundings constantly shift which does not affect them. Workers' clothing changes on their bodies without them noticing, people they are conversing with disappear. At one point, office workers engaging in a meeting suddenly stick together as if drawn to one another by static electricity. Other men in the room begin to contort others' bodies, tying each other into knots with their own limbs. Two men outside shake hands and, when their hands touch, both men melt into one another, emerging after a few seconds having reversed all physical characteristics. People who work in the office also seem to have god-like powers, changing things as simple as the lighting in the room, to as impossible as causing people to walk on the ceiling rather than the floor – all by changing settings on their computers.
