Slight thread derailment, but we saw him do a joint talk at BlueDot Festival a year or so ago and I've never been more disappointed. He was doing the talk with the guy who crafted Darth Vaders helmet and then there was a Q&A afterwards. The guy couldn't have given less of a damn about Star Wars, frankly. The answers to pretty much all questions were disappointing, he cared little for the film, which if you're doing a talk in front of a thousand people you'd expect he'd show one scintilla of adoration for. Frankly, it came across as just a thing that made him tonnes of money. I suppose you can't blame him for that, it was a job, but if you are going to go on public speaking events then you at least have to act like you wanted to be there! The helmet/model maker was infinitely more interesting and engaging.
Remembered well for the Green Cross Code Man, of which he was very proud of.
You should watch ‘I am your fathers documentary on Amazon prime. Interesting watch, I think that made him very anti Star Wars in his later years.
