The incredible (and somewhat predictable) success of Avatar at the box office (and the Golden Globes) has everyone talking about a sequel to Avatar.  In fact, this quote from James Cameron suggests a trilogy:

To some it’s a mashup of “Dancing With Wolves” and “Ferngully: The Last Rainforest.” But James Cameron’s “Avatar” has stormed the international box office with a global taking of more than $1.6 billion and may very well be on its way for a sequel … or two.

“I have a trilogy-scaled arc of story right now,” Cameron told MTV. “But I haven’t really put any serious work into writing a script.”

Avatar is highly derivative of other stories and science fiction, and as an avid reader of the genre, I thought I could take a crack at a potential, obvious premise for the backstory of Avatar 2.

Premise: It’s five years after the first movie.  There has been peace on Pandora, as Sully and Neytiri have ushered in a new age of cooperation and understanding between the tribes of the Na’vi.  The humans have been evacuated, with the exception of a small set of scientists who have been given permission to continue their efforts to bridge the learning and knowledge of the two cultures.

However, there have been unusual occurrences on the planet.  The behavior of the flora and fauna on Pandora has been unpredictable, confusing Neytiri who utters more than once that “this has never happened before”.   Modifications of some species begin to appear, as well as completely unknown species are discovered.  The scientists can’t explain it, and Sully tries more than once to communicate with Eywa, with no answers.

Silently, a massive human invasion fleet is on its way to Pandora.  The resources of Pandora are too valuable, and once the Na’vi attacked the corporation, it justified a larger military involvement at 100x the scale of the original movie.

It turns out, however, that the biology of Pandora was too idealistic to have naturally evolved.  After all, every creature sharing a common communication link is incredibly unlikely.  10 foot humanoids with carbon fiber skeletal structures also seems a little far fetched.  It turns out that Pandora is a very special planet, because it’s entire eco-system of creatures was engineered by an advanced race.  That race left Eywa, a massively parallel organic computer, in place, dormant, to monitor the situation and ensure that Pandora progressed as planned.

When Eywa awoke, it began taking emergency measures to modify and enhance existing species against the potential threat.  And it sent an interstellar signal to its creators, to let them know that all was not well with Pandora.  That’s right.  The creators are coming…

… there.  That’s enough for Avatar 2.  Avatar 3 can then focus on what the master plan of the creator race was after all, when the Pandora experiment goes awry.

Given the evolution of the Aliens story (also by James Cameron), I actually think this is a plausible direction.  There is a parallel between the plot surrounding a single ship facing one alien in the first movie, and a massive military engagement with a massive alien force (and new creatures) in the second movie.

Please note: I have absolutely no data whatsoever about the actual direction of Avatar 2.  This is just speculation on my part, as a science fiction lover.  Any reflection of the real plot or premise for Avatar 2 is purely coincidental.
