With Rogue One in the books, we now have a good idea of what a standalone Star Wars movie is going to look like. It also means we can start turning our heads to the Young Han Solo movie now too.
It seems the film is on the verge of getting an important block in place too. Variety are saying that Woody Harrelson is the top pick to play Han's mentor. It's said this is still early stages, but right now, he is who the production wants.
As a wily scoundrel mentor for wily scoundrel young Solo, Harrelson more than has enough experience in that kind of role. Makes sense to me.
