Star Wars Post found an interesting quote from Donnie Yen, who did a Reddit AMA today:
At Star Wars Celebration, Gareth Edwards (Rouge One: A Star Wars Story‘s director) made it pretty clear there are no Jedi in this film and it is about normal people needing to rise to the challenge and deal with the Death Star problem as soldiers. God is not going to save you, you have to save yourself is the idea. For this reason, I doubt Yen teasing he’s a Jedi in the next Star Wars film.
While there is always the crazy chance he’s an ex-Jedi turned bounty hunter rebel, I’m just going to say “no” to the idea until there’s actual evidence beyond cute slogan use to evade saying anything that violates an NDA. Yeah, the Maz type of character is possible though.
Donnie Yen should be proud to be the first Chinese actor in a starring role in Star Wars. That’s pretty cool.
