We are just a few months away from the highly-anticipated Obi-Wan Kenobi series set for Disney+. While Lucasfilm/Disney+ has kept details guarded, prior reports revealed Obi-Wan will not only have to deal with Darth Vader but inquisitors as well. Thanks to a new report, we know which actor is playing one of these roles.

According to Bespin Bulletin, a Star Wars site with a good track record, Rupert Friend (Hitman: Agent 47) will be playing the Star Wars: Rebels character the Grand Inquisitor. The site also goes on to say that along with Friend, Moses Ingram (The Queen’s Gambit) and Sung Kang (F9) are also playing inquisitors.

For those unfamiliar, Grand Inquisitor, also known as Master of the Inquisitorius, was a title used by the highest-ranking Inquisitor of the Galactic Empire. The Pau’an male and former Jedi Temple Guard known only as the Grand Inquisitor, and sometimes the Inquisitor, held this title, and was ranked above other Inquisitors such as the Fifth Brother, Sixth Brother, Seventh Sister, Eighth Brother, and the Ninth Sister. As Grand Inquisitor, he reported to Darth Vader, a Dark Lord of the Sith, and hunted Jedi who had survived the Great Jedi Purge.

The Inquisitor who held the rank of Grand Inquisitor was a villain created for the animated television series Star Wars Rebels, and he made his on-screen debut in the 2014 television film Star Wars Rebels: Spark of Rebellion. He is voiced by well-known English actor Jason Isaacs (Harry Potter franchise). The Grand Inquisitor appeared in a number of episodes until his death in the season one finale, “Fire Across the Galaxy,” but the rank of Grand Inquisitor was never referenced in the first season. His rank was first revealed by series executive producer Dave Filoni in a preview of the second season on the Star Wars Rebels: Complete Season One home media release.

Set to take place decades between Revenge of the Sith and A New Hope, other plot details on Obi-Wan Kenobi are currently being kept close to the vest. Deborah Chow, who helmed several episodes of the first season of The Mandalorian will both produce and direct the entire series which is reported to consist of 6 hour-long episodes.

Hayden Christensen will return to play Darth Vader, with Joel Edgerton and Bonnie Piesse also returning in their original roles from the franchise. The remaining cast consists of Moses Ingram (The Queen’s Gambit), Kumail Nanjiani (The Big Sick), Indira Varma (Game of Thrones), Rupert Friend (Homeland), O’Shea Jackson Jr. (Straight Outta Compton), Sung Kang (Fast and Furious franchise), Simone Kessell (Terra Nova), Benny Safdie (Pieces of a Woman), and Maya Erskine (Pen15).
