The live action Star Wars show was to be about the underworld in Star Wars. Think the Sopranos in space and you're just about there.

They wrote a bunch of scripts and then realized it was too cost prohibitive to do for television and so they put it on the backburner and were going to wait it out for the costs to go down.

1313 was supposed to be a sort of tie-in to the show and kept going forward into production long after they shelved the show. Then of course that eventually got cancelled.

Rebels is an all new show with no ties to any of the previous efforts.

At least Tim Curry's accent sounds English, the actor who's doing Tarkin's voice sounds a bit Australian

I think Stephen Stanton did an excellent job as Tarkin.
