== Technical credibility ==

The idea of parts of two consciousnesses inhabiting the same brain already has scientific precedence, with the observation of people with multiple personalities, including cases in which the corpus callosum joining the two hemispheres of the brain is severed [http://www.nature.com/news/the-split-brain-a-tale-of-two-halves-1.10213].

What is less credible in this film is the idea that consciousness might be transferred from one brain to another by a machine that is described as "being like a giant magnet". If any such technology does become available in the future, many other aspects of technology and society are likely to be fundamentally altered beforehand. This is in contrast to the plot in this film, in which the "shedding" mechanism is available in a world that has very few other differences from the present day.
