A semi-long but interesting documentary about people who play Quidditch in real life. The game actually looks really fun, even if the hipster population seems a bit high.
Dutch documentary The Making of the Empire Strikes Back never saw a commercial release but contains a fascinating and rare glimpse behind the scenes of the beloved film. The language quickly switches to English, which is convenient, but you'll have to bear with the shoddy quality (it's worth it). Part Two is here.
