Heath Ledger's Death the X-Factor?

I think more people went to see the movie than there would have been just to pay respect to him. But i do think he would/will have won an oscar because he did so well in that movie, but i don't think as many people would have gone to see it if he hadn't have died. but then again they might have because the roll he played in the movie was so different than any he has done before. it doesn't bother me that they are making a big to do over the movie because for one i think the movie deserves it and i think heath does too.
