Mark Hamill has been known to speak frankly and off-the-cuff - but he's equally known to obfuscate reality with half-truths and teases that leave multiple interpretations wide-open. During a conversation with Ray Davies of the Kinks, focused mostly on the band's history for The Big Issue, the subject of Star Wars, where the actor has played the hero Luke Skywalker for four decades, did come up eventually. Unlikely, but possible spoilers for Star Wars: Episode VIII and Star Wars: Episode IX follow.
"I finish Episode VIII, and then I'm out of work," Hamill said when asked about his future with the franchise. Of course, the report, from Den of Geek, came with zero context - we don't know how the question that led to that statement was phrased, we don't know how Hamill delivered that particular quote, or what the general conversation even was when it was said.
Most likely, this is not Hamill spoiling anything about the next two episodic films in the Star Wars franchise. More probably, Hamill was speaking of his immediate plans, saying he didn't have anything directly on his schedule after wrapping Episode VIII. With no production schedule yet for Episode IX, let alone a finalized script, it's not something that'd even be on the actor's radar just yet. His regular work in video games, film, and TV, as The Joker and other characters, may also see a lull as well, since his work for season one of Justice League Action, his work for July's Batman: The Killing Joke, and his work for Batman: Arkham VR in October would all be long-since completed at this point.
Hamill loves to tease, but has never let out an outright spoiler, and it's not likely he started now, at a public conversation about a rock group. Still, reports of the final sequence being shot had only Daisy Ridley (Rey), Mark Hamill (Luke Skywalker), and Adam Driver (Kylo Ren) present in Ireland at the real-life location of the fictional First Jedi Temple. That is the kind of showdown that could result in a death.
We won't find out Luke Skywalker's fate for sure until Star Wars: Episode VIII (not final title) hits theaters December 15, 2017. Until then, always in motion is the future.
