The corpus callosum is a central region of tissue in the human brain which passes "messages" between the two hemispheres. *Corpus Callosum, the film, is constructed of, depicts, creates, examines, presents, consists of, and is, "betweens." Between beginning and ending, between "natural" and "artificial," between fiction and fact, between hearing and seeing...*Corpus Callosum juxtaposes or counterpoints a realism of normal metamorphosis (two extreme examples: pregnancy, explosions) in believable, "real" interior spaces with "impossible" shape changes (some made possible with digital animation). First the camera, then we in the audience, observe the observations of the "real" people depicted in the obviously staged situations....The film is tableaux of transformation, a tragicomedy of the cinematic variables.
