Hot on the heels of Making Star Wars’ Rebels tidbits (some of which they repeat,) TFN says they know what fandom has blown up to be the biggest mystery of Rebels: The voice of the Inquisitor. And he’s not an announced member of the Episode VII cast, though he will be familiar to genre fans of various stripes… Head below the cut for possible spoilers.
Highlight to read the black bars: Jason Isaacs will be voicing the Inquisitor, their source claims. He is, of course, known to genre fans for playing Lucius Malfoy in the Harry Potter films, and voicing General Zhao on the first season of Avatar: The Last Airbender - which Dave Filoni worked on before leaving for The Clone Wars.
I suspect they may be holding back announcing these villain castings (the source also claims that TFN’s earlier guess at Agent Kallus was correct) for extra publicity pop until we get closer to the show’s premiere date… Whenever in the fall that ends up being.
