Think you've met every actor in the "Harry Potter" franchise? Think again.

Our friends at Film.com have scored this exclusive clip from the "The Harry Potters You Never Met" featurette in the Harry Potter Wizard's Collection arriving in stores on Sept. 7. In it, you can see how the stunts from the movies were performed, from rehearsal to filming, as well as meet the unsung heroes of the series: the cast's stunt doubles.

You may not be able to shake their hands, but at least you'll be introduced to some more of the magical creatures who worked on the series.
