The Acolyte -- a Star Wars television series described as a "mystery-thriller" -- is currently in development for Disney+ from Leslye Headland, creator of Netflix's Russian Doll.
The Acolyte was announced by Lucasfilm president Kathleen Kennedy as part of Disney Investor Day 2020. An official description on the official Star Wars website explains that the series is "a mystery-thriller that will take the audience into a galaxy of shadowy secrets and emerging dark side powers in the final days of the High Republic era." No further plot details have been revealed at this time, nor is any information available regarding casting or a release window.
In addition to The Acolyte, a number of other Star Wars projects were announced for Disney+ during Disney investor day, including two Mandalorian spinoffs: Ahsoka and Rangers of the New Republic. A special event series titled Lando was also announced, as were two animated shows: A Droid Story and Star Wars: Visions. Updates were also provided on previously-confirmed Disney+ releases such as Andor and Obi-Wan Kenobi. Moreover, it was announced that Wonder Woman director Patty Jenkins would be helming a new Star Wars film titled Rogue Squadron.
