Are you a fan of poor-quality videos with shaky-cam, taken straight from a movie set without any of the sound replaced and tons of green screen? Then do we have something great for you!
In all seriousness though, the two B-reels that Warner Bros. has released from the Harry Potter and the Deathly Hallows: Part 2 set is rather interesting. We get to see our first glimpse of Aberforth Dumbledore and his rockin' beard in action, as well as B-rolls of some scenes which were previously released as finished clips. For instance, did you know the door to the Chamber of Secrets is an actual prop, and not just CG?
I've embedded both videos below.
