Although Mark Hamill did warn Star Wars fans to stop asking him about the upcoming Episode IX, that clearly doesn't mean he's against rehashing previous films and confirming what exactly happened to his character.
Hamill confirmed the Force is what killed his character, Luke Skywalker, in The Last Jedi, and he didn't hesitate in pointing out how ironic it was. Earlier this week, the actor tweeted a series of photos recounting Luke's fate:
At the end of The Last Jedi, Luke used the Force to project himself across the galaxy to confront and battle Kylo Ren as a means of stalling the approach of the First Order so that Leia and the rest of the Resistance could escape.
Despite having seen Luke literally vanish into thin air at the end of The Last Jedi, Hamill has confirmed that he will make an appearance in Episode IX, with many fans suspecting he'll appear as a Force ghost.
You can catch what will likely be Hamill's last reprise of Luke Skywalker when Star Wars: Episode IX hits theaters December 20, 2019.
