Quite a bit of new deleted scenes info. up at avpgalaxy.net and amongst the forum comments there.
Guy Pierce does an awesome job in the full 7 min. 'younger Weyland' speech, and really gives the character some much-needed background gravitas. It's 'subtitled' Long Beach, California. 2023 at the beginning of the footage now, and I definately hope that any future fanedits will include it somewhere after the 'Sacrificial' footage and 'Main Titles'.
Sadly, I think it's unlikely that any of this footage will actually get integrated in any potential official 'Extended Cut' that Ridley may release in the future, as this great 'viral' scene-setter was actually directed by his son I believe. So that might be a problem possibly. If it isn't, it would be a great loss to the movie as far as I'm concerned, as I reckon any future cut would be the poorer for not using (at least some of) this footage eventually.
I'm looking forward to seeing all the others too eventually, but it's a real pity they aren't all being included on the standard DVD release as well.
