The director sold his Star Wars franchise to the company back in 2012 for a reported $4 billion, and the first film under the new name has just been released - 'Star Wars: The Force Awakens'.
But speaking about the takeover in a new interview, it seems George isn't entirely happy with his decision and the latest movie.
Speaking to American talk show host Charlie Rose in a lengthy chat, George said: "Disney said we want to make the new trilogy for the fans. So I said all I wanted to do is tell the story of what happened. You know, it started here and it went there. It's all about generations and it's about the issues of fathers and sons and grandfathers -- it's a family soap opera, I mean, ultimately. We call it a space opera, but people don't realise it's actually a soap opera. It's all about family problems. It's not about spaceships.
"So they decided they didn't want to use those stories. They decided they were going to go do their own thing. I decided, Fine, but basically ... they weren't that keen to have me involved, anyway. But at the same time ... if I get in there, I'm just gonna cause trouble, because they're not gonna do what I want them to do. And I don't have the control to do that anymore -- all I would do is muck everything up. So I said, Okay, I will go my way, and I'll let them go their way.
"These are my kids. I loved them, I created them, I'm very intimately involved with him, and I sold them to the white slavers that take these things and ..."
George's comments tailed off at that point, with the film legend laughing somewhat nervously.
