One thing that a live-action Clone Wars story would do, that Ewan McGregor also seems excited about, is that it would bring Hayden Christensen’s Anakin Skywalker and Obi-Wan together again.
Seeing The Clone Wars in live-action certainly has appeal.
Rosario Dawson, of course, has appeared as Ahsoka Tano in live-action, her character was originally introduced in The Clone Wars series as well.
The Obi-Wan Kenobi series on Disney+ was only ever presented as a limited series, indicating that a second season wasn’t specifically planned, but Ewan McGregor is up for returning, and he even has an idea of what he wants to do with it.
