"The DNS hijacking attack was resolved within an hour, Moore said."
Is that a DNS joke?
Are you... serious?
Nope; the two sets (upper and lower ship) were both contiguous sets since the TV series. I don't think there are shots even close to the movie's opening in the TV show (given the nature of TV and when commercials need come in), but the two ship sets were always contiguous, complete with roofs, practical lighting, etc. It's one of the more impressive sets in TV history.
Joss Whedon's Serenity features a nearly ten-minute long scene with no visible cuts (there is technically a seamless dissolve half-way through for technical reasons -- watch the DVD commentary and you'll see what I mean). Whedon didn't do it to show off or grab attention, but actually to make the audience feel safe and trusting after the rapid cuts and scene/flow changes found at the very beginning of the film.
I find rapid cuts annoying and a way to draw the viewer away from a lack of detail or a scene that can't carry itself on the acting/sets/dialog/action alone. I don't seek out long takes though -- like most things in movies: if they're done really well you shouldn't be thinking about them, but rather about the plot.
