Tagne of StarWars-Universe.com found that the Star Wars live-action show is listed as being in pre-production by the Screen Australia (Warning: PDF link) website. He contacted Lucasfilm, who said:
The live-action series is still too far off for any immediately impending announcements, but feel free to keep checking in!
Screen Australia is probably jumping the gun – we have nothing solid (only hearsay) about casting yet, and if Wikipedia is to be trusted (I know, I know,) that at least would come before pre-production began officially. But the fact is, Lucasfilm is playing things close to their chest at this point, so we just don’t know.
It’s not much, but hey: Any little bit, right?
