After seeing the thread started by unoyt SAI about the crimson room puzzle
and trying to solve that riddle I wonder if that was based upon this movie
" SAW" starring Danny Glover, Cary Elews. Just saw this movie and I highly
recommend watching it, now be warned Horror/gore type movie with blood
but also a real sense of terror as well. It is also very intelligently written and
directed with a real surprise ending.
