Comparison between the original Theatrical Version (R-Rated) and the Unrated Director's Cut, both included on the US DVD released by Shout Factory.
Even though the Director's Cut offers almost 5 minutes of additional footage, it doesn't really add any important scenes (regarding plot and violence). The Director's Cut mainly consists of many small additions - here and there, there's an additional sentence or alternative footage. Also, the Director's Cut has an awful image quality, so you should rather watch the Theatrical Version. If you watch the movie in a dark room you will probably not be able to see too much.
In the scene where Jummy disposes of the bloody carcasses from the lab, the Theatrical Version offers some sort of synthesizer music, whereas the Director's Cut at this scene uses "The Blue Danube" by Johann Strauss. You might know this classical song from Stanley Kubrick's 2001: A Space Odyssey. The same thing also occurs in the scene where Barbara cummunicates with the creature via the computer.
In the Director's Cut SAM has a distorted computer-like voice. In the Theatrical Version it seems to be a little more human (and almost a little feminine).
Runtime of the original Theatrical Version (without credits): 1:15:33 (NTSC)
Runtime of the Director's Cut (without credits): 1:20:28 (NTSC)
77 differences = 294 sec. (NTSC)
The black screen at the beginning of the movie is shown minimally longer in the Director's Cut.
When the camera pans to Mike Colby who's asleep, you see a fast cut of several scenes that will later on re-occur in the movie. At some points of this scene, the DC shows different pictures.
