A new behind-the-scenes feature on how some of the scenes in final three Harry Potter films were brought to life with the assistance of production designer Stuart Craig and special effects head Tim Burke was released as part of the definitive Harry Potter Wizard's Collection, out in early September.

This new clip, which will be seen on the never-before-seen video "Expanding Beyond The Page" from the Harry Potter film collection, can be viewed below. It contains new on-set clips of the cave in Half-Blood Prince and Godric's Hollow in Deathly Hallows: Part 1.
