A few weeks ago Star Wars The Last Jedi was unveiled as the longest Star Wars movie ever made.
The sequel to The Force Awakens is 15 minutes longer that its predecessor at two and a half hours.
Now Luke Skywalker star Hamill has spoken out on his initial shock to the news.
Speaking with Vanity Fair, he said: “I was appalled when I heard that.”
He added: “In fact the most important line Luke says is, ‘This is not going to go the way you think.”
Star Wars Episode VIII: The Last Jedi will be released in UK cinemas on December 14, 2017.
