Two of the "Big Three" actors from the original Star Wars film trilogy have known about plans to produce Episodes VII, VIII, and IX since last summer, according to Mark Hamill. The actor who played Luke Skywalker toldEntertainment Weekly's Josh Rottenberg that George Lucas sprung the news on Carrie Fisher and him during a lunch that Lucas organized in August. Here's more from the article:
I thought he was going to talk about either his retirement or the Star Wars TV series that I’ve heard about — which I don’t think we were going to be involved in anyway, because that takes place between the prequels and the ones we were in and, if Luke were in them, he’d be anywhere from a toddler to a teenager so they’d get an age-appropriate actor — or the 3-D releases. So when he said, “We decided we’re going to do Episodes VII, VIII, and IX,” I was just gobsmacked. “What? Are you nuts?!” [Laughs] I can see both sides of it. Because in a way, there was a beginning, a middle, and an end and we all lived happily ever after and that’s the way it should be — and it’s great that people have fond memories, if they do have fond memories. But on the other hand, there’s this ravenous desire on the part of the true believers to have more and more and more material. It’s one of those things: people either just don’t care for it or are passionate about it. I guess that defines what cult movies are all about. We’ll see.
