Why wasn The Terminator (1984) originally filmed in stereo?
Although stereophonic sound existed in 1984, The Terminator (1984) was filmed in monophonic. This was because during the production, the budget was too low to allow the filmmakers to get all the effects they wanted and still allow for the film to be shot in stereo. Although a stereo remix was produced later for the Hemdale VHS release, it was not until MGM acquired the rights to the film that a fully recognizable 5.1 stereo soundtrack was created, for the 2001 Special Edition DVD.
