When we say expanded cinema we actually mean expanded consciousness. Expanded cinema does not mean computer films, video phosphors, atomic light, or spherical projections. Expanded cinema isn't a movie at all: like life it's a process of becoming, man's ongoing historical drive to manifest his consciousness outside of his mind, in front of his eyes. One no longer can specialize in a single discipline and hope truthfully to express a clear picture of its relationships in the environment. This is especially true in the case of the intermedia network of cinema and television, which now functions as nothing less than the nervous system of mankind.
