There have been plenty of rumors floating around about what Star Wars characters might star in the spinoff films Disney is planning.
Disney previously confirmed the first two stand-alone Star Wars movies would be directed by Chronicle and Fantastic Four director Josh Trank, and Godzilla director Gareth Edwards, but that's literally all we know for sure.
Han Solo and Boba Fett have both been floated as possibilities in the past, but Slashfilm points out that an anonymous source on Making Star Wars says Obi-Wan Kenobi is the likely choice to get a stand-alone film.
The full quote:
Obi-Wan Kenobi – I’ve heard from quite a few people now that an Obi-Wan Kenobi movie is in the works. For the spin-off movies they were initially going to stay away from any Jedi or Sith characters. But I’m hearing now that because of the popularity of Obi-Wan (fans recently voting for him on the official website etc) that an art team is now working with a writer on concepts for an Obi-Wan movie.
This could be good. Of course, we don't know if this would be some kind of origin story of a young Obi-Wan, or perhaps cover some of that time between Episode III and Episode IV, when Kenobi went from this,
For what it's worth, Ewan McGregor has said he's down for this.
