Star Wars is just a movie, and the Star Wars movies are just movies, which is probably why I like Mark Hamill's sense of humour regarding his role in the franchise.
Spoiler for some: I learned just a few months ago that Luke Skywalker was killed-off. This vital bit of intelligence came about when a friend asked me: "Do you know....? Do you know about....?" My response was honest: "Go ahead. Tell me. I'll probably never see (the films), anyway."
A Washington Post interview with Mr Hamill:
