WOW, so many great books becoming movies!! I'm SO excited! I know that Shailene Woodley was casted as Tris but as I don't have so many scenes with her that I can use I just had to use Teresa Palmer (which is an amazing tris too). Hope you like it guys! If you haven't read this series yet, you definitely should read it ! book 1 is called "Divergent" & it's AMAZING !
