Cinelinx reports today that Star Wars casting people weren’t just looking for folks for Episode VII, but for unannounced projects including “specials and mini-series.” (via)
Their speculation that includess the Darth Vader special we heard of seems off-base – I’d guess that’s more of a documentary/existing footage thing.
A live-action show is certainly not outside of the realm of possibility, though Disney and Lucasfilm have claimed that they’re focusing on Episode VII (and Rebels) right now. Waiting until the new movie era is firmly established – as Marvel did – would be the smart thing, I think.
