What has been confirmed for production in addition to Ewan McGregor as star and Deborah Chow directing is that Hossein Amini of The Alienist will write the series, with Kathleen Kennedy, Tracey Seaward of The Queen, and John Swartz of Rogue One are on board as executive producers.
So, in addition to the prequel trilogy star and a Mandalorian director, the Obi-Wan series has the Lucasfilm president and a Rogue One alum in the mix.
No wonder the project will fit seamlessly into the saga!
