This set is a pretty comprehensive collection that includes all 8 HP films (including extended versions of several film that were exclusive to the Ultimate Edition releases, but not including the 3D versions of Deathly Hallows Pt.1 & Pt. 2) and pretty much every bit of previously issued bonus / supplemental content released for each and every film.
