Just for s's and g's, what if someone did a "depressing 70's edition" and took the bomb explosion from RAMBO (recoloring the foliage to the more bluish tinge) to signify the bomb being dropped (even if the shuttle gets destroyed) on the Tree of Life? I know it would be hard to edit in scenes from other movies, as AVATAR is 100% CGI, but still... I can wonder...

BTW, if the subtitles are removable, would it be possible to rewrite the Na'vi dialogue? Also, would it be possible to edit out the scenes in the briefing room showing the blatant rednecks sitting in the crowd?
