Avatar 2, 3 and 4 plot is extremely interesting but details about James Cameron's upcoming sequels are hard to get.

Thankfully, The Hollywood Reporter had a talk with "Guardians of the Galaxy" star Zoe Saldana, who's been really very series with her movies that also include a Star Trek 3 sequel.

When asked about what she can tell about Avatar 2, 3 and 4 plot, she had this to say:

"I wish I knew! I've been told by Jim [Cameron] that it'll be about an overall spiritual journey, but I don't have a script."

The interview continued with Saldana comparing her upcoming films GOTG and Avatar. Both requires for her to extremely change her skin color from blue in Avatar and now green in Guardians of the Galaxy.

"This time it was actual makeup. Avatar was motion-capture, so everything was done in post. But Guardians was the way it's normally done. You get picked up at 3:30 in the morning and spend 4½ hours getting things glued and spray-painted on to your face."

When ask which movie she liked better she simply said:

"Avatar. Working in the volume, doing performance-capture. Because you don't have to worry about what you're going to look like. That gets added later. You just play the character."

Meanwhile, director James Cameron is determined to make Avatar 2 plot more mind-blowing and he has been working faster based on the amount of development and computer graphics to make the second movie of the series exceed the expectations of the audiences.

"The first film... took almost four years to make. We expect to be able to accelerate the process quite a bit, because we've improved a lot of the software and the computer graphics tools, and we've been working very closely with Weta Digital down here in New Zealand developing a whole new suite of tools to speed up the process."

James Cameron also revealed that the team is simultaneously working on the plot of the next three sequels of Avatar.

"The second, third, and fourth films all go into production simultaneously," he wrote on a Reddit Ask Me Anything session last weekend. "They're essentially all in pre-production now because we are designing creatures, settings, and characters that span all three films. And we should be finished with all three scripts within the next, I would say, six weeks."

Cameron provided a sneak peak in Avatar 2 plot in an interview that there would be new worlds and new characters that would be introduced in the second installation of the hit scifi franchise.

"We're still in the early stages. Right now we're developing the software. I'm writing the scripts. We're designing all the creatures and characters and the settings, and so on. So, I'm not actually directing yet, but I'm doing all the other creative processes that lead up to that. It's going very well. I think it's going to be spectacular. You'll see new worlds, new habitats, new cultures. The primary conflict between the human view kind of dominating nature and the Na'vi view of being integrated into nature is the same, but it manifests itself in very different ways," he said in an RTL interview.

Meanwhile, director of Titanic and first two installations of the Terminator series also expressed his enthusiasm with 3D as he wants the Avatar 2 and all its planned sequels to be released in 3D.

"I believe all movies should be made in 3-D, forever, but the projection needs to be better and brighter," he wrote during his AMA. "I want people to see in the movie theaters what I am seeing in my perfectly calibrated screening room and people aren't seeing that. Larger formats. I'd love to see screens get bigger."
