Just because the "Harry Potter" franchise is gone doesn't mean it's forgotten. On Sept. 7, Warner Bros. will release a ridiculously comprehensive set containing all eight "Harry Potter" films spread across 31 DVDs and Blu-rays. (Expecto patrohmygod, right, guys?)

To celebrate the release -- which you're obviously going to ask for this holiday season -- HuffPost Entertainment is happy to debut one of the set's special features, a 90-second clip focused on how Rupert Grint cannot keep a straight face.

Watch above as Grint -- who played Harry's faithful sidekick, Ron, in the films -- cracks up during numerous scenes throughout the franchise.

"Harry Potter: Wizard's Collection" arrives in stores next week.
