Harry Potter And The Deathly Hallows

The way I understand it, the first half won't be 3D because they were already too far in production to add it properly, and they didn't want to just tack it on, but the second half will be fully produced for maximum 3D effects.

Part one will be the more boring "plot setup" half anyway, it's the second part that will rock with lots of magical battles and effects.

As for the books...

I read years 1-4 four times.
I read year 5 three times.
I read year 6 twice.
I read year 7 once.

Next time I plan to read the series, I'll read 4-7.
