McGregor took over the role of Obi-Wan for the Star Wars prequel trilogy two decades ago from the late Alec Guinness.
Chow, Amini, and McGregor will serve as Executive Producers alongside Kathleen Kennedy, Tracey Seaward (The Queen) and John Swartz (Rogue One: A Star Wars Story).
Unfortunately, the dismal box office performance of Solo: A Star Wars Story put all the spinoff movies on hold.
Obi-Wan also had a memorable rematch with Darth Maul in Star Wars Rebels.
