Ever since J. Michael Straczynski started selling his Babylon 5 script book series, I’ve been hoping we’d get a book with the scripts from the spinoff Crusade. Especially the scripts that were finished, but never produced, and would have set up the real story. That whole thing about finding a cure for the Drakh plague before it wiped out Earth? JMS strongly hinted at the time that it wasn’t going to be the main arc, but rather the mission that got the Excalibur out there and exploring, at which point they’d get caught up in the main story.
Two of the scripts were made available briefly on an e-reader site, using a Java applet that was specifically designed to make it as hard as possible to copy and paste anything (and incidentally made it a serious pain to, y’know, read it, which may be why the site is long gone). As I recall, they included a project to reverse-engineer Shadow technology, and the first hints that the Technomages used Shadow tech (before Jeanne Cavelos’ novels fleshed out that connection in detail.)
Anyway, we’re still waiting for the Crusade scripts, but here’s the next best thing: Crusade: Behind the Scenes.
Characters, story, world-building, production issues and design, executive meddling, interviews with the cast and crew, photos, etc.
There’s a note at the end of the write-up:
CRUSADE: Behind the Scenes does NOT contain any of the show’s scripts. It is a compilation of interviews and images. The Crusade scripts, including those that were never filmed, will appear in J. Michael Straczynski’s forthcoming 3-volume series, “CRUSADE: What the Hell Happened”
Sadly, given the title, I suspect the script books are a joke. But who knows? Stranger things have happened with B5.
