"Monday, July 18, marks the 30th anniversary of the debut of Aliens, so EW asked Weaver, director James Cameron, and producer Gale Anne Hurd to reminisce about that final knock-down drag-out. Cameron: I did the initial drawings. I presented them to Stan Winston, and then the next thing was, all right, now how are we going to do this damn thing? Because you got to remember, there was no CGI back then. So, you know, we’re talking about big puppets, miniature puppets, and maybe some guys inside it, and I said, well, I think you can put guys inside this thing. I think you can put two people inside it. He thought I was nuts. So we did a test where we built a frame that could hold two people. Hurd: You’ve got to remember the state of computers back then also, this was not a time of microcircuitry that’s as advanced as it is today. There were robots in manufacturing lines, and we used some robotics in the film, but it was first generation. If it could be choreographed with people, it’s much easier to tell someone what you want to do and how to change something in a nuanced way. And it’s less likely to break!"
