Nowadays, no DVD release of a blockbuster [and frequently, lesser] movie is complete without a "making of" documentary. Well, don't expect Harry Potter and the Deathly Hallows; Part 2 to be left out.

I don't know who came up with it, but a Quidditch broom for whomever invented the title: When Harry Left Hogwarts. A trailer for Morgan Matthew's film has just hit the Internet:

The 48-minute documentary [The trailer you just saw contains one-twelfth of the final film] looks at the making of both parts of the Deathly Hallows adaptation, wrapping up a 10-year, 8-movie series, based on the books written by J. K. Rowling.

When Harry Left Hogwarts is included on the Blu-Ray two-disc release of Harry Potter and the Deathly Hallows, Part 2, due out November 11th.
