There have been quite a few theories online on who might take on the iconic role of Admiral Thrawn in live-action. Many hoped that Lars Mikkelsen would once again play him after bringing him to life in the animated Star Wars Rebels series but many thought they might head into a completely new direction as they did with Ahsoka, who is now played by Rosario Dawson.
Theories have ranged quite a bit with even Robert Downey Jr. at one point rumored to potentially take on the role. On the first day of the Star Wars Celebration, we got a tease of Thrawn in the live-action trailer for Ahsoka, but only his back. Instead of letting us wait until these series releases in August, the second day they just flat-out confirmed during the Ahsoka panel that Mikkelsen will indeed reprise the iconic role.
