personally, I'm expecting a massive disappointment with this one. After Lotrs came out (sorry, lotrfan) I have no confidence in directors and screenplays based off of books. If the casting isn't botched up (which it probably will be if Freddy Highmore or Keira Knightly end up getting signed on), then the plot will be all mashed up and the characters will suffer. Aaarrgh.
Honestly? I cannot think of one movie I have seen that does justice to the book it was based off of. Sorry to sound like the voice of doom here, guys, but this is going to be a flop. f.l.o.p.
