I'm amazed, no shocked! that I have friends and colleagues who have neither read the Harry Potter books nor seen the first seven films about the boy wizard. If you have any of these colleagues or friends, you can send them this link and tell them to catch up on everything in seven minutes, just in time for Friday's U.S. launch of the final film.
The awesome Fine Bros., who also brought us the 47 years of Doctor Who in 6 minutes video, do their very best to update you on the first seven movies. Grab your wand and enjoy!
