This news is a few days old now, but Lucasfilm has announced that the Obi-Wan Kenobi Disney+ series will be directed by Deborah Chow. Although it isn’t confirmed I figure this announcement means its safe to assume that she will direct all the episodes of the show. No other directors were announced with the release.
Chow has already done some work in the Star Wars galaxy. She was one of the directors for The Mandalorian. So its probably safe to assume that Lucasfilm was happy with her work and brought her in for another show. She’s directed many TV series at this point in her career including Jessica Jones, American Gods and Better Call Saul.
Stephen Daldry, the director of Billy Elliott and The Hours was originally believed to be involved in this project when it was still expected to be made into a film. That was never officially confirmed. So, its possible that he may have abandoned the project somewhere down the line, or he simply never was involved in the project in the first place.
