Star Wars Rebels Actor Open to Reprising His Role in Live-Action If the right project and the right script came along, Star Wars Rebels actor Jason Isaacs says he would be happy to bring his Grand Inquisitor character to life in a Star Wars project. In the years since the character debuted, fans have only grown more interested in the villainous figure, thanks to the role he served in the overall scheme of the franchise. Prior to Season Two of The Mandalorian, many fans thought it was just wishful thinking that Isaacs would play the live-action version of the character, but with that season seeing Bo-Katan Kryze and Boba Fett played by the performers who voiced them in their animated appearances, it seems more likely that such casting could happen.
