The Quadrilogy DVD was branched (for economy of disc space) so the two versions had to be matched in terms of colour manipulation... this might not necessarily be so with the Blu-ray.

Perhaps Jonno...but I'll be surprised if we see the original ALIEN colour again, now that Ridley has chosen to alter it in the first place. Although some may like it, his new color-timing is too dramatic a change from the movie's original colour-palette for my taste. While the 'Quadrilogy's improved print was great to see, the unnatural-looking colouration throughout ruined it for me. Some aspects were darkened, while others had a 'washed-out' insipid look to them, and just didn't look as good on the eyes overall I thought. Give me the vibrantly red blood and natural colours of the sets etc. from the original DVD, any day.

Just as a reminder of how things look now, here are a few comparison examples. The original DVD's colour is shown at the top, while the 'Quadrilogy's revisionist colour is underneath -

As far as the forthcoming Bluray anthology goes, I just hope they don't DNR the hell out of ALIENS like they've ended up doing to the latest PREDATOR release! But it's good to see that the 'Burke's cocoon' scene is included in the extras, and that they've gone to the effort of fixing the moments of poor audio on the extended ALIEN 3 cut. And interesting to see that Fincher's comments are uncensored this time round too. I'd just like to see ALIEN's original colour back, though.

And even though the mystery of the 'Space Jockey' is going to be diluted in future, at least we've got Ridley back for the Prequel(s). Let's hope he's still got it in him!
