There’s only ever been the Dolby 2.0 Surround on home video although the initial release had Dolby Six-Tracks (probably 4.2) on the 70mm roadshow prints. The recently broadcast HDTV version apparently had Dolby Digital 5.1 that was less active than the stereo DVD.

These are the versions as far as I remember:

The only two really important versions are (1) The International Theatrical Cut (2) The 1992 Director’s Cut.

For fans there’s also (3) The incomplete Workprint version (4) The censored US Theatrical release (5) The censored US TV master with additional line of dialogue.
