Luke Skywalker, right now, is the last Jedi. There's always wiggle room in these movies - everything is from a certain point of view - but coming into our story, he is the actual last of the Jedi.
I do think that I'm a big believer in having an idea or having ideas and just tucking them away in the back of your brain. Even if you aren't consciously thinking of them, I think they simmer. You're working on them, even if you don't know you're working on them, and I think having something in your head for a while is a valuable thing.
Showing your movie to an audience... it's like your kid doing a piano recital. 'Just let it not fail. Please.'
Ray Bradbury was the first author that I was really exposed to back in grade school. I'm a big Philip K. Dick fan, but the emotion and humanity that Bradbury brings to his stories and the way he uses sci-fi to get at the human heart is something that's unique and for me incredibly influential.
It was so emotional to step onto the Millennium Falcon set because that was the play set we all had when we were kids. Suddenly, you were standing in the real thing. There's this rush of unreality about it.
As to whether Luke is the 'Last Jedi,' they say in 'The Force Awakens' he's going to find the last Jedi temple and Luke is the last Jedi.
