Trailer Released For Insightful Documentary When Harry Left Hogwarts

This. Looks. Awesome.
Check out the trailer (above) for the upcoming documentary When Harry Left Hogwarts, which gives what appears to be a VERY in-depth look into the making of Deathly Hallows: Part II!
We’re sure there’ll be seventeen different versions of the final Harry Potter film released on DVD/blu-ray, but we just wanna make sure we grab a copy with that doc on it! Looks seriously interesting!
Will U check out When Harry Left Hogwarts when it gets released next month?
