With regard to Rogue One; I hope he isn’t in it at all. And yes, I realize that’s very unlikely. If he is, I’ll be glad if it’s just a scene or a name-check. I’ve never found him to be interesting. Not when I was a kid in 77, not in the 80s films, not now. A movie without him would be just fine with me.
Perhaps this will change your mind about him.
