Ok, I have only read about a million times on the web about J.K. Rowling saying things put in the Potter movies that were unintentional that is in relation to something in the final book. I have watched them all over and over for the past week and can't find anything relating until I was reading in the Deathly Hallows thread and saw where CloudDragon said this:

They went after him because he had a part of Voldy's soul inside him. Also think back to the comment Rowling made about Cuaron unknowingly and unintentionally putting things in the movie that greatly foreshadowed events in the last two books. Could this have related to the dementors?
That to me made me think a little and that is actually a good theory. So, other than that, I still can't think of anything, so is there anything you guys have seen that you may believe will have a part in The Deathly Hallows?
