Ewan McGregor has confirmed that his return as Obi-Wan Kenobi wasn't originally going to be a streaming TV show. In an interview with ComingSoon.net, the actor said he prefers the extended serial format as opposed to a single film.
"It wasn’t always going to be a series, not initially," McGregor said. "When we first started talking about, that wasn’t really in the cards but everything’s changed so much, so quickly. It’s really exciting that it is now. I’m really into the idea to be able to tell the story over several hours instead of just one hit. I think it’s going to be quite cool."
In 2017, Lucasfilm was reportedly courting Stephen Daldry to direct a standalone Obi-Wan Kenobi film in the vein of the various A Star Wars Story films.
McGregor said that he had been in talks with Lucasfilm to return as Kenobi since 2015, and that the first season of the show is currently estimated to be six hour-long episodes in length.
