Liam Neeson said on Jimmy Kimmel Live! last night that he hasn’t been approached to return as Qui-Gon Jinn in Star Wars: Obi-Wan Kenobi.
Of course, this kind of statement should be taken with a grain of salt. Maybe Lucasfilm asked the cast and crew not to reveal certain things for now.
As a reminder, Qui-Gon managed to return as a spirit after his death, although he can’t appear in a physical form. The Jedi Master gets back in touch with his former Padawan learner Obi-Wan between Episodes III and IV, and teaches him the secrets of immortality. The new series is set precisely in this era.
I hope Neeson is lying. It would be silly to waste this perfect opportunity to bring back the great Qui-Gon Jinn on a big Star Wars project.
