What is perhaps original to this film is that it is such a mundane man and such a mundane day. Too much has been made of how this mundanity leads to great spiritual awakening. There is nothing particularly religious or spiritual about what happens to our trapped protagonist. The truths he apprehends tend to be the same philosophic truths that do not require revelation to apprehend; they are part of the common store of humanity. Though at times we forget or ignore them, they are the province of the Gods of the Copybook Headings.
