The parallels between RT and todays society will likely be used, the energy crisis for one. The LOTR perspective is also one that would work too. as long as they dont rush it , then it should be ok not taking into account CGI and character useage. if they go for only slightly bigger than human aliens then the whole point of the VF1 is lost it was after all built with fighting 50ft alien troops in mind. As far as casting its adead cert that they wont get the people who would fit the roles exactly but the will re hash the story to make them fit. Just as long as they dont put it in the blender to re hash it.
