About this Mark Hamill hullabaloo:
I have not visited the thread (as a matter of personal policy I do not willingly jump into volcanos), so I apologize if this has been brought up there. From the comments I've seen, Mark seems somewhat frustrated at being lead to believe that his role would be bigger in the movies. When George first contacted him about the sequel trilogy in the summer of 2012, he told Mark that his idea had Luke playing a prominent role in Episode VII. And judging from Mark's comments, the rough plan at the time was for Luke to continue to have a big role in VII and IX. But when Michael Arndt tried to take the outline he'd worked on with George And turn it into a script, he ran into problems. Luke took the focus away from Rey. And it almost didn't matter how much or how little Luke was in the movie, he still messed up what they wanted for Rey. So eventually, in December 2013, after Arndt had left the project, the story finally got nailed down. Luke would barely feature at all, just popping up in the final scene (and ever so briefly in a flashback). He wouldn't even have a line. But by this point, Mark had spent a year and a half assuming that he had a pivotal role in the film. I can imagine he was frustrated. Especially as the original star of the series. But Mark's a team player, and there were still two more movies where he could be prominently featured. Then Rian talks to him and reveals Luke's death in VIII. Now Mark is frustrated all over again. He's been reduced from a key role in three movies to a key role in one movie, and cameos in the other two. And that one movie where he gets a spotlight, it's in a much different form than what he's done before in the series. He won't be the calm, powerful, heroic teacher. No, he's the scared, weird recluse. And I didn't even mention all the crazy stuff George may have told him while making the original trilogy! Remember, while filming Return of the Jedi Lucas told Hamill about plans for a sequel trilogy that would start filming around 2011. For all we know, George promised him a big role back then. This had to be aggravating. So I get why he'd have complicated feelings about the films.
