We are Wizards

While searching through documentaries on NetFlix, I found a movie that followed Harry Potter zealots entitled "We are Wizards." Halfway through, I realized it was extremely pertinent to our class readings because it started concentrating on the copyright issues that were taking place between fans and Warner Bros. In fact, the author, Henry Jenkins, had a few cameo interviews.



After seeing the movie, I couldn't help but wonder how all this copyright pishposh could possibly seep into the classroom. Say, for example, I start teaching middle school and assign my students a video project after they read a Harry Potter book. Now, what if after the class, they post that video to youtube and somehow get in trouble with the Warner Bros. guys. Could I, as the teacher, possible face any legal charges?

I guess this is a stretch, but I am just curious of how all the copyright laws are stated. Does anyone have knowledge in this area?
