I knew these weren't 3D, otherwise, the marketing people would've been fired.
ALSO, PJ mentions on the hobbit 1 commentary that the forced perspective thing done on these films, were impossible to do for The Hobbit, since 3D would kill the illusion, as you can't fool it. SO, I don't know if a post convertion is possible to begin with due to that fact, second, with so many effects done with models (which I do prefer to CGI, however), I don't know how a 3D could look like. I mean, like by the end of TTT, the river flooding Isengard really looks a bit WTF, how would that translate to 3D? Or the snow covering the fellowship on FOTR? Shots that really show it was 2000 tech and that they were 95 Million dollar movies each, and not nearly 200 as the hobbit ones. (And that was with MASSIVE tax incentives by NZ government, mind you).
I am getting this babe, since I figure Hobbit 2 and 3 will get the same treatment, so will kick some butt to have all 6 films on matching steelbooks (I mean the size).
