I guess all that fan foot-stomping may finally be paying off. The Hollywood Reporter is saying that Stephen Daldry (Billy Elliot, The Hours) is in “early talks” to direct a standalone starring Obi-wan Kenobi. It’s in “the earliest of stages” and there’s no script yet, so I don’t expect we’ll hear anything official from Lucasfilm anytime soon. (EW’s Anthony Breznican also seems positive on it – though again, “very early.”)
It’s not known if Ewan MacGregor will return, but he’s been open to the idea ever since the standalones actually became a thing.
