Star Wars: The Last Jedi director Rian Johnson and franchise veteran Mark Hamill initially weren't on the same page about Luke Skywalker. Hamill revealed to ScreenRant how Johnson surprised him with this new approach to Luke. Asked if his vision for the character and Johnson's vision lined up, Hamill said, "No."

"[T]he most shocking thing I read was it's time for the Jedi to end. Are you... What?" he revealed. "I mean, I understood Luke's regret at being wrong about who the chosen one was and he feels responsible for creating potentially the next Darth Vader and hey, I mean, ruining your nephew's life. Like not perceiving that he was going to the Dark Side until too late, so that weighs heavily on him."

Hamill explained that, like in every three-act story, the characters face their greatest challenges in the second act. "I mean this is where all the darkest things happened," he shared. "I mean, there's triumphs of course, but more than its share of tragedies."

"It's like the movie, it's just mindbogglingly complex. It's challenging. It's hilarious in parts. It's suspenseful. It's dark and somber. I'm holding the fort down on the dark and somber," he said.
