The Matrix trilogy ("The Matrix", "The Matrix Reloaded", and "The Matrix Revolutions") used early Virtual Cinematography techniques to develop virtual "filming" of realistic computer-generated imagery. The result of John Gaeta and his crew at ESC Entertainment's work was the creation of photo-realistic CGI versions of the performers, sets, and actions. Their work was based on Paul Debevec et al.'s findings on the acquisition and subsequent simulation of the reflectance field over the human face acquired using the simplest of light stages in 2000. Famous scenes that would have been impossible or exceedingly time-consuming to produce within the context of traditional cinematography include the burly brawl in "The Matrix Reloaded" (2003) where Neo fights up-to-100 Agent Smiths and the beginning of the final showdown in "The Matrix Revolutions" (2003), where Agent Smith's cheekbone gets punched in by Neo leaving the digital look-alike unharmed.
