Mark Hamill is in the unique position of returning to the Star Wars movies or disappearing entirely. Both would make sense — which isn’t really the normal way of doing things when your character has been killed off. Add in the tragic passing of Carrie Fisher, and things get more complicated.
Harrison Ford’s Han Solo certainly isn’t returning — even if the character's role with the franchise is changing. But, because Luke Skywalker is a powerful Jedi Master, he could always return as a Force Ghost — able to talk, move, and manipulate objects from beyond the grave — in J.J. Abrams’ Episode IX.
Yet even with this opportunity, the actor’s incentive to return has been greatly reduced since Carrie Fisher, the third of the original films’ starring gang, whom Hamill called "irreplaceable," tragically passed.
The joy of the new films has been “tarnished,” Hamill told ABC News in an interview also including his wife and daughter. “You asked earlier, ‘Are you going to come back?’ I don’t care anymore,” Hamill explained. Fisher’s death so greatly affected him and his family that it’s hard to get excited about a false spirit of getting the band back together.
That band has been irreparably changed, though when it comes to Fisher, “rather than be sorry that we can’t have more of her,” Hamill is “just grateful that we had the time with her that we did." Luke’s return to the franchise, especially after Yoda had a movie-stealing scene in The Last Jedi, seemed inevitable even if his body had passed off this corporeal plane. Now, with Hamill’s excitement for the series waning, it almost seems cruel to push him back on board.
