Wes Chatham and David Tennant have joined the cast of the upcoming “Ahsoka” series on Disney+.

According to Deadline, Chatham will portray Admiral Thrawn’s right-hand man, but no other details are available. Lars Mikkelsen is reprising his role as Thrawn, which he originated in “Star Wars Rebels.”

Tennant will reprise his role as the droid Huyang. He voiced Huyang in a series of “Clone Wars” episodes, in which he taught Jedi younglings how to construct their lightsabers.

Ahsoka

“Ahsoka” stars Rosario Dawson as Ahsoka Tano. Ashley Eckstein originated the voice role in the animated “Star Wars: The Clone Wars” in 2008. Eckstein also voiced Ahsoka in “Star Wars Rebels” and, most recently, in “Tales of the Jedi.” Dawson took over the live-action version of the character in “The Mandalorian” season 2. She reprised the role in “The Book of Boba Fett.”

“Ahsoka” will act as a spin-off from “The Mandalorian,” but also follow up on the cliffhanger of “Star Wars Rebels.” At the end of “Rebels,” main character Ezra Bridger sacrificed himself to defeat Grand Admiral Thrawn by jumping into hyperspace with the purrgil (space whales). His friends Sabine Wren and Ahsoka Tano then vowed to find him and departed together at the end of the series.

In “The Mandalorian,” Ahsoka was seen searching for Thrawn on her own. “Ahsoka” will pick up on her and Sabine’s search for Ezra, who was originally voiced by Taylor Gray and will be portrayed in live-action by Eman Esfandi.

The first “Ahsoka” trailer was recently released at Star Wars Celebration, giving the first good look at Mary Elizabeth Winstead’s Hera Syndulla and Natasha Liu Bordizzo’s Sabine Wren, both characters who originally appeared in the animated “Star Wars Rebels.”

Sabine was originally voiced by Tiya Sircar in “Star Wars Rebels” and “Forces of Destiny.” Hera was voiced by Vanessa Marshall in “Rebels,” “Forces of Destiny,” an episode of “The Bad Batch,” and the video game Star Wars: Squadrons.

Hera Syndulla was the captain of the “Star Wars Rebels” team. Her droid, Chopper, will also appear in “Ahsoka,” and possibly her young son, Jacen, who only appeared briefly in the final moments of “Star Wars Rebels.”

Hayden Christensen is also set to reprise his role as Darth Vader in “Ahsoka.” When he was part of the Jedi Order and still going by Anakin Skywalker, Vader trained Ahsoka. They last encountered each other in “Star Wars Rebels.”

Another main character from “Star Wars Rebels” recently made his live-actiond ebut in “The Mandalorian.” It hasn’t been confirmed if he will appear in “Ahsoka,” too.

Lucasfilm also announced three new standalone “Star Wars” films and the return of Daisy Ridley as Rey. They released the first teaser trailer for “Ahsoka” starring Rosario Dawson as the titular Ahsoka Tano, who first appeared in “Star Wars: The Clone Wars” and then made her live-action debut in “The Mandalorian.” They also released “The Acolyte” footage exclusively at Star Wars Celebration. “The Acolyte” stars Amandla Stenberg as the titular acolyte and Lee Jung-jae as a Jedi master. Footage from “Rogue One” prequel “Andor” season 2, starring Gabriel Luna, also premiered.
