Where to begin (book plot to movie plot): [quote] First off, this trailer gave away many of the interesting plot twists of the book (Ender being the last Cadet, Mazer Rackham was thought to be dead but he is alive because he traveled in a space ship around light speed around Saturn) Secondly, Ender himself did not know he was ever killing any of the buggers, Mazer told him it was "all a simulation". Finally, most of Ender's game takes place in Ender's mind and is his own thoughts and feelings. He did not like killing and regretted killing the buggers home world.[/quote]
