Sixth Scale Man
Super Freak
A FB group I'm in has a guy who works at Disney/Marvel in it. He claimed HT has worked on ESB Han and from what he says Disney has signed off but Ford hasn't. So that may be the simplest answer instead of HT being dumb about releases, if they need his approval and they haven't gotten it, their hands are tied. He said Fisher's likeness is controlled by her estate and is obviously a lot easier going since they've used the same face 3x now.
That's especially frustrating if he signed off on the goofy trooper (Goof Troop?) Han but is holding up a Bespin one. C'mon Harry!
