Death Star is the story we wanted to tell. Like Titanic, everybody knows how it ends, no tension there. We intended it to be a character piece from the git-go.
The DS was a small planet, and the idea of it being nothing but troops in barracks hanging around and waiting to fight didn't make any sense to us -- people are going to have to live on the thing for years, and there's no place to go for liberty -- nobody is allowed to leave -- so it has to be a city in space, with everything you'd find in any big city. Of course there were women on it, and women like to shop.
Just because they didn't focus on that in the movies doesn't mean it wasn't there. You ever see anybody using a toilet on the DS? Or eating? Taking a shower? Just because those weren't shown doesn't mean they didn't happen ...
It was a construction project. First time they take it off to war, Luke blows it up, so it wasn't ever going to be about fighting. It was going to be about who was on it, which of them survived, and answering a bunch of questions Reaves and I had about it -- who ran it, what people did when they were off-duty, how it got put together. Who fired the big gun ... in the original script, it was Darth Vader who pulled the lever.
Why that exhaust port was there ...
If you stayed up until one a.m. reading it, that works for me ...
