Mark Hamill has opened up about the original ending for Star Wars: The Force Awakens, and why it had to be changed.

Last year, the actor revealed the ending of The Force Awakens was altered at the last minute, after they spotted something that would have contradicted the events of The Last Jedi.

In a new interview, Hamill said the ending would have seen Luke Skywalker surrounded by ‘floating boulders’ to demonstrate his use of the Force as Rey approached him on Ahch-To.

Of course, The Last Jedi begins with the revelation that Luke is no longer using the Force, which would have made it difficult to explain those floating boulders. (Helium?)

“When we were doing [The Force Awakens], Rian said, ‘We might have boulders floating to show your Force emanating’, so I was led to believe that I still had the Force and it was really strong in me,” Hamill said.

“When I read [The Last Jedi] before [The Force Awakens] came out, I said ‘what?!” and called JJ [Abrams] or Rian [Johnson] to say, ‘Are you guys aware of this? Have you seen a cut? Is there floating boulders?’

“And they said, ‘No, we caught that and we worked it all out’.”

Hamill’s of course had to talk about Star Wars a lot in recent years, and not all of it can be gold – the actor recently admitted he regretted publicly voicing doubts about The Last Jedi.

“I regret voicing my doubts & insecurities in public,” Hamill wrote on Twitter. “Creative differences are a common element of any project but usually remain private.

“All I wanted was to make good movie. I got more than that – @rianjohnson made an all-time GREAT one! #HumbledHamill.”
