Hamill: "I did regret maybe not having the three of us on-screen together one more time."
On December 18, 2017, Rolling Stone published an interview with Mark Hamill regarding The Last Jedi. The interviewer asked him about the rationale behind, and his feelings on, having only a very brief contribution at the very end of The Force Awakens. Here's what he had to say:
First of all, once I came around to what it was going to be, it made complete sense. If I were in the position of a J.J. Abrams or a Rian and thinking, "I've gotta close out the Han Solo story, I've gotta introduce this whole new set of characters, I've gotta set up this whole new conflict," wouldn't it be much easier just to push me to the next chapter? I did regret maybe not having the three of us on-screen together one more time. But again, at times, I'd say to Rian, "We gotta think of what the audience wants." And he'd say, "No, we've gotta think of what we want." Which is a learning process for me.
So like many fans, Hamill laments the lack of an on-screen reunion of the original characters, but he also recognizes that fan service is not necessarily in the best interests of developing a story.
