Harry Potter documentary gets a teaser trailer

It looks like the Harry Potter franchise is going to get a Making Of for the DVD or Blu-ray that goes beyond the back-slapping efforts of most Hollywood blockbusters.

Documentary maker Morgan Matthews was given access to the set of The Deathly Hallows Parts 1 and 2 and When Harry Left Hogwarts is the result.

The teaser starts with the filmmaker bravely asking cast members what they think the doc should be about.

"It would be nice if it was talented," says Gary Oldman (AKA Sirius Black). "Most of these things are awful."
