When Disney announced it was doing a Han Solo spin-off movie, many fans wondered what that actually meant. Would it be an origin story? Or maybe just show him on one of his early adventures? According to Lawrence Kasdan, who is writing the film with his son, Jon, the film is going to focus on the moments that made the smuggler who he is today.

Speaking on the Empire Film Podcast, Kasdan explained that the film isn’t going to be a complete examination of his life, and instead see what events formed the person we meet at the Mos Eisley Cantina in A New Hope.

“It is not so much about his specific history,” Kasdan said. “It is about what makes a person like that. He’s not fully formed in the cantina. Kurosawa once said, ‘The heroes are the ones who are still changing and the villains are locked and petrified into what they are.’ Harrison embodies in The Force Awakens someone that’s still not settled on who he is.”

Although the original trilogy gave Solo a believable arc from smuggler to hero, his backstory was never actually revealed or talked about. Whether we actually need that information is another matter entirely, but Disney wants to give it to us whether we like it or not.

In an earlier interview, Lucasfilm president Kathleen Kennedy revealed the movie will identify an event, or events, in Han Solo’s life “that gives you some idea of who he is.”

“We don’t want to spend time going back and answering a lot of questions that, quite frankly, I don’t think people want answered,” Kennedy said.

Last we heard there were over 2,500 potential candidates vying to play Han Solo, giving you an idea how coveted the role is. Maybe even more than how the actual story plays out, getting the casting right will be crucial to the movie’s success. We’ll find out when the film hits theaters in 2018.
