Firstly, from one of my best sources, it is true that there is no final script or breakdown yet. There is a breakdown of the Jake / Warrior King story arc however. Further, entire sequences and situations that were developed during the production of AVATAR that were intended for the sequel(s) or simply couldn't make it into original are queued up too.
I have this confirmed from three top sources. Another source said "Yeah no ready script at all. What I've heard it's more of a pitch. But the storyline and where the characters go is already there and quasi discussed. I don't know where he (Cameron) is, but he's not in the states."
Yet another source said: "News will start to gather soon on Jim's next adventure into another world "or two", I do have news for your readers, I have heard Jim wants to push the Alien world further into the abyss. Pandora best prepare for all war, because I promise you it's on it's way."
And don't forget what we already think will take place: AVATAR 2 will continue several years after the events of the original. The oceans play a key role. It will also lay the groundwork for the other moons in the system. Things are going to get quite "weird" to the point of becoming somewhat abstract! Each movie will stand on its own and there will definitely be NO shooting the sequels back to back. Trilogy? Actually no. The sky is no limit for this universe - the plot lines are endless.
And of course don't forget this AVATAR 2 SPOILER ALERT: This is verbatim from my source... "Oh and Pandora has a lot of shit coming its way. Break out the space marines, looks like some bugs need a stomping."
The first two quotes are from this week and those last two quotes were from late April / early May and things can change of course, especially as JC has not finalized a script but it certainly is VERY interesting. More when I get it guys. It is very hard to acquire anything that isn't there yet! But as you know we have the best internal sources for AVATAR right here and when I get - you will get it!! Hang on, it will be a heckuva ride in the coming months.
