I only hope that Von Sydow doesn't initially appear as a friendly and helpful character. He's always the bad guy in films so you'll inevitably just be waiting for him to show his true colours!
There's no Lando Calrissian? . I thought that was a good character, he's really smart and inspiring, designing stations and cities in weird places and getting thousands people to settle there to work and live with him (I did read the books with Admiral Thrawn, he set up a mining operation or something around a extremely hot star and you had to take special measures to get to the place without getting cooked)
He stays such a nice guy and honest when he betrays you, I would like to be betrayed by him.
