Just watched the 'Assembly Cut' of Alien 3 for the first time. Have to say, it's a much better film with the extra scenes - much more depth added to more minor characters, and makes the movie much more atmospheric to watch. Those early, establishing shots of the beach, the external shots of the prison etc. I might be wrong but I felt there were quite a few scenes where a few extra lines of dialogue were added (mainly between Ripley and Clemens).
Alien 3 has always been my second favourite Alien movie (I know it is widely hated on here and elsewhere), but this 'Assembly Cut' version takes it to a greater level. Wish Alien 3 had more love!
