Harry Potter and the Deathly Hallows?

I am reading the last book and I want to know how far i have to read in order to watch 'harry potter and the deathly hallows part 1.'Harry Potter and the Deathly Hallows?
I would read the entire chapter of The Wandmaker (chapter 24). The movie does not include everything from that chapter, but the movie ends with the event that takes place right at the end of chapter 24, so if you don't want to be spoiled at all, you need to read until (at least) the end of The Wandmaker. I don't think anything beyond that is included in the movie.Harry Potter and the Deathly Hallows?
It's pretty hard to tell, because the movie changed a bit around, but on average the movie ends in the middle of Chapter 24, the wandmaker. Don't read the entire chapter though, the movie ends right after... um.. if you haven't read the book before, i'm not going to tell you what harry does, but it's around this paragraph:



"He looked down at his handiwork for a few more seconds, then walked away, his scar still prickling a little and his mind full of those things that had come to him in the grave, ideas that had taken shape in the darkness, ideas both fanscinating and terrible."

I would say up to Chapter Twenty Four (The Wandmaker).
