Colonel John Matrix [disambiguated: Matrix ]
Fictional featured character in the 1985 film Commando starring action star and former Mr. Universe Arnold Schwarznegger , directed by Mark L. Lester. Matrix is a former green beret remarkable for his ability to remain unphased in the face of ultra-violence, perhaps due to transcendent awareness of his participation in a celluloid-based narrative, a phenomenon commonly called "the Matrix Effect", with the term matrix here referring not only to the character's nomenclature but the pixel-based fabric of spacetime as described in quantum loop gravity ¹ .

¹ The term "matrix" here also relates here both to William Gibson 's conceptualization of cyberspace and to the development of control parameters (including tone rows, dynamics, etc) in the Second Viennese School .
