 Although stereophonic sound existed in 1984,  _Terminator, The (1984)_ (qv) was filmed in monophonic sound. This  was because during the production, the budget for the movie was  pretty low. The cost for everything else in the movie added up to  the crew not having enough money to produce The Terminator in stereo  sound. Although a stereo remix was produced later by the Hemdale VHS  release, it was only until MGM acquired the rights to the film that  they were able to create a fully recognizable 5.1 stereo soundtrack  for the 2001 Special Edition DVD.
