On Thursday, the first sign that it may actually be happening arrived: Borys Kit of The Hollywood Reporter published a story saying that filmmaker Stephen Daldry is in talks to direct the project.
If it happens.
That's important: EW's sources say there's still an ”if" involved, but yes — we can confirm this is a movie that's being actively explored as a possible stand-alone beyond 2019's Episode IX.
A source close to the filmmaker suggested it is far from a done deal, calling the news ”premature, at best."
As of now, there is no script and no cast. But any film like this would want to secure a filmmaker before taking those steps, so McGregor's involvement is certainly a possibility.
There's a good reason for Lucasfilm to wait until after Episode IX to explore Obi-Wan's backstory and his time in the Tatooine desert before we meet Alec Guinness' portrayal in the first movie: They're still figuring out how he connects to the new saga, which started with The Force Awakens.
