The reason 'Avatar' sequels are taking so long…

Walt Disney World has treated guests to the Tomorrowland, Neverland, and now the famous theme park is inviting fans to visit the land of “Avatar.”

“Pandora – The World of Avatar” opens to the public this weekend at Disney’s Animal Kingdom park in Orlando, Florida. The colorful attraction, replete with towering alien creatures and glowing plants, was inspired by director James Cameron’s 2009 blockbuster “Avatar,” which took place on Pandora, a lush, green moon inhabited by the Na’vi species.

It took roughly six years to build and comes with a price tag that is reportedly in the range of half a billion dollars, making it one of the resort’s most ambitious undertakings.

CNN spoke with Cameron at the land’s dedication on Wednesday about working with Disney, creating Pandora both on and off screen, and why he’s taking his time with those highly-anticipated “Avatar” sequels.

The following conversation has been edited for length and clarity.

So, when did you first know that “Avatar” could actually become a real world?

Well, Disney came to me and said we want to take your movie and turn it into a land. Not a ride. A land. A place to go and be and smell and walk through and experience and have it surround you. And I thought, okay… that’s a bit of a challenge. You guys are biting off a big one this time. And then they took me and showed me the model of what they proposed to build and I was stunned by the scope of their vision and imagination.

Now I’m used to being the one who does that, you know? And getting everybody else afraid that it’s not possible or it’s not gonna work. So the shoe was on the other foot and I thought alright, there’s gonna be budget cuts. Some adult is gonna come in and stop them. And you know what? They played through, and they delivered on every promise and beyond.

What is quintessentially James Cameron about the land? I know you worked with them on it.

I did work with them on it, but I don’t want to take credit because, you know, [Disney Imagineer] Joe Rohde, who was the real guy with the vision for this, he just embraced and carried the torch of the idea, the themes about indigenous culture and ecosystems and conservation work. He took all that and he basically offered this whole narrative around this land where you can come, you can visit, and the war is over, the conflict between the humans and the Na’vi is in the past and you can just soak it in.

Yes, I was involved to make sure that they weren’t sort of drifting away or doing things they shouldn’t do. But this is really Joe’s vision and the Imagineers… It was a great collaboration.

“Avatar” came out roughly a decade ago.

No, no, no. Let’s not exaggerate. Seven-and-a-half years.

Okay, seven-and-a-half years ago.

You’re off by 25%!

Do you feel that that kind of gap in time hurts those who are truly engaged with this land at Disney’s “Pandora?”

Well it didn’t hurt “Avatar,” that there was no “Avatar” before “Avatar.” So I kind of rest my case.

But it was a seven year gap between “The Terminator” and “Terminator 2: Judgment Day,” seven year gap between “Alien” and “Aliens.” It’s gonna be obviously more like a ten year gap between “Avatar” and “Avatar 2.” But “Avatar 2” you are going to with not the promise, but the certainty of three more films beyond that, and that’s a very different concept with the audience. And a lot of the delay has been around creating that overall vision.

And by the way, this land will help bridge that gap in the public conscience. People will come here, and say, man I need some “Avatar.”

Throughout your career your films have had very strong social commentary. From artificial intelligence in “The Terminator” series to the environment in “Avatar.” What do you think is one of the biggest dangers in society right now?

I think our disregard for natural systems and our kind of overshoot as a species consuming everything in sight, you know? I think that the real battle of the future, philosophically, is gonna be between the takers and the caretakers. The takers are ascendant right now because in their mind, if you’re not a taker, you’re a loser.

So not “Skynet” though. The battle won’t be with “Skynet”?

I didn’t say Skynet might not be a part of that. So yeah that’s another danger, but I don’t think it’s our main danger. Because that’s a huge variable… But we know for sure that the big danger is our overshoot as a species, as a civilization.
