Note that since it is an early test version, this explains why it has differences in music and dialog editing than other mixes of the film.
The 70mm mix that actually ended up being presented to the public in 1979, then, would have been a 4.1 track with identical content to the 35mm stereo version. Such a track can be found on the official Bluray release, as 640 kbps AC3. The surrounds are mono and the amount of bass is somewhat less than in the test version, but it is more finalized in editing and content than its predecessor.
Taking this into consideration, for the sake of authenticity I would say that any project proclaiming to be Alien in 70mm should include both the laserdisc 5.1 and the Bluray 4.1 versions, and that they should be clearly labelled for what they are.
Editing to add: Furthermore, we can also infer from this that the 4.1 track on the Bluray of Aliens really is that film's 70mm mix, as well.
Thanks hairy_hen. Yeah I've seen Disclord's posting over at the LDDB before (he also put that info in the notes for the LD). The man knows his stuff backwards and forwards. He is the reason why I know Die Hard on LD was 70mm and the original Terminator 2 DVD was the CDS mix.
I suspect the reason Fox made note of it being a 70mm mix on the LD jacket is because it was different to all previous home video versions. Its easier to say hey this is a 70mm mix then explaining sensurround testing, etc. Like I said earlier they had used 70mm mixes on LDs before without note. The only question is why did they use it instead of the "true" 70mm mix. Frankly I don't care, its a pretty cool track. And we have access to both mixes.
There was a lengthy discussion on the the Alien soundtracks here:
http://originaltrilogy.com/forum/topic.cfm/Dolby-Digital-41-Surround-Alien-Anthology/topic/13986/
Where msycamore (is he here anymore?) was nice enough to put together the differences (he is referencing Jonno's 2.0 capture):
Personally I'm very fond of the polished 35mm but absolutely love the dynamic range, bass, clarity and some of the more subtle variations heard in this mix. I can tell you that the discrete version is not that huge of a difference from the 2.0 version, some fx are awesome with more clearly defined surrounds (the sound of the chains before Harry Dean Kitty Crap Stanton gets killed for example) but it's still a quite front heavy mix like many mixes were at the time (just the way I like it, too many films nowadays keep the surrounds too busy)
Some of the more obvious differences in content compared to the 35mm Dolby Stereo mix (will try to make a complete documentation at some point) you'll probably notice right away in this mix if you're familiar with the 35mm:
-Jerry Goldsmith's score on the title sequence and opening is a little bit different, pay attention when we first enter the corridors of the ship, the 35mm is scored right away.
What appears to be a distant horn emanating from Nostromo when we first see the ship is absent.
-Dallas line "Good morning, Mother." is an alternate take.
-Kane's line "Roll 92 degrees port yaw." is absent.
-Lambert has an additional line of dialogue heard when they prepare to land on the planet, "900 meters and dropping." (subtitled on the 20th anniversary DVD)
-From the moment when Nostromo is approaching the planet until they enter the atmosphere, the sound editing is very rough with a few alternate cues heard. (Deep bass from the engines)
-Right before the Space Jockey scene, Kane's lines "Come on down here. Something different down here..." are absent.
-When the crew discusses Brett's death, Ash's response "Kane's son." is absent.
Also, you might have noticed something odd with this track which is noticeable right before they land on the planet, the score in particular sounds like it's played in the wrong pitch/speed for a moment. Perhaps the sound elements used was in bad shape or something? Anyway, not my doing.
I have zero idea how this is going to be released and in what form it will take, either BD or MKV. The form might dictate how many soundtracks I can shove on. The plan, which will change, is:
Pan and Scan LD PCM 2.0 Mix - Hopefully close to the original Dolby Stereo
Widescreen LD 70mm AC-3 5.1 DD Mix - The test 70m track
1999 DVD 5.1 AC-3 DD Mix - This is really a 4.1 mix (mono surrounds) so it was rumored at the time it came out to be the refined 70mm track.
Beyond that I can add if space:
Quad DVD AC-3 5.1 DD Mix - This is the first true 5.1 track on DVD. It has stereo surrounds.
BD 4.1 - I strongly suspect this is the same track as the 1999 DVD but won't know till I pull them both to compare. If it is different I will include it over the 99.
Thanks for the input hairy_hen
PS. All this talk of 70mm tracks, makes me wish I could get a hold of the Alien 3 test 70mm track they talk about on the docs. Apparently they put a ton of infrasonic sound in the mix. They had to tone it down for the finally release.
