Ever since James Cameron admitted that an "Avatar" sequel was in the works there has been almost never-ending speculation as to when it would shoot and what it could be about. Will the Na'vi travel to other worlds?  Will they go to Earth?  Will stars Sam Worthington or Zoe Saldana even return? With a quick, no-frills release of the movie on DVD and Blu-ray on Earth Day, producer Jon Landeau added fuel to the fire while speaking to the press this week.

According to I09, Landeau said that Cameron's recent trip to South America has been key in determining the direction for the sequel.

"We recently made a trip down to Brazil and learned a lot," Landeau said. "Not just about the world and what's going on the issues there, but how it relates to Avatar and the world of Pandora. Jim meeting indigenous tribes down there, we are a culmination of our past experiences. And these experiences like in Brazil and presenting on the 24th, Avatar to the indigenous tribes United Nation here in New York. All of that is going to inform us about Avatar 2."

He also confirmed that he would "think" the movie would take place on other worlds besides Pandora.  As for all the other rumors, Landeau joked, "[Do] you believe everything you read?"
