Years ago, I talked with Dark Horse Comics about writing an Aliens mini-series for them. (Do they still use that term?) I ended up doing a couple of treatments. They rejected the first one for being too similar to the 4th movie (even after a rewrite), but they couldn't tell me how because the movie wasn't out yet. At the time, I was actually happier with the second treatment, but Dark Horse brought in a new editor, who introduced a new Aliens "bible," and the storyline didn't fit within the guidelines. I grew frustrated and gave up. I still regret that a little.

The Prometheus trailer "felt" a bit like that second story: polished and lofty with a mythological ambience. The recent Battlestar Galactica series had a bit of that flavor too, but not as bright.

Leif Jones was going to be the artist for the story. He was less excited about the second treatment than the first because one of the things he loved about the original movie was the straightforward sensibility of the technology. The people who built the Nostromo didn't spare much energy on beautification. Almost everything about the ship felt functional. Over time, I have come to see things the way Leif did, which is why I'm not as excited about this new movie (after seeing the trailer) as I'd hoped to be. 

If you wanted, I imagine that you could work out a deal to write a story set in that "universe," particularly with the new movie coming out.
